SUMMARY<br />
Today, ‘green buildings’ have become one of the most famous and<br />
fastest growing construction and design concepts; in fact, green<br />
buildings are doubling every three years worldwide. Owners, developers,<br />
architects, designers and even consumers are realizing its importance<br />
in sustainability, and expressing deep interest in the cost-efficiency,<br />
energy saving solutions, modern design, and the quality of life that such<br />
buildings are offering to present and future generations.<br />
Due to the built environment<br />
playing such a substantial role in the<br />
sustainable development discourse,<br />
Green Buildings hold particular<br />
importance, especially in cities; this<br />
is largely because buildings are the<br />
largest energy-consuming sector<br />
worldwide – accounting for more<br />
than 40% of global energy-use and<br />
responsible for an estimated 30% of<br />
city-wide emissions.<br />
In addition, buildings hold the most<br />
promise when it comes to “potential for<br />
global energy savings”; the International<br />
Energy Agency posits that the world’s<br />
built stock accounts for up to 41% of<br />
global energy savings potential by 2035.<br />
This is primarily due to green buildings<br />
using ~40% less energy and ~30%<br />
less water than in standard buildings<br />
of the same size. Furthermore, there<br />
are roughly 8-<strong>10</strong> million new buildings<br />
constructed each year, worldwide.<br />
Imagine a world where each of those<br />
new buildings erected each passing<br />
year were resource- and cost-efficient,<br />
consuming less energy and water,<br />
releasing less CO 2<br />
emissions, improving<br />
air quality, and built to be more durable<br />
than our standard building stock; the<br />
world would undoubtedly be making<br />
a gigantic step towards sustainable<br />
development and the greater good.<br />
Although the area of sustainable and<br />
green development has received<br />
a lot of attention from researchers<br />
and practitioners, with many papers<br />
being published on “Green Cities” or<br />
“Sustainable Cities”, very few public<br />
papers have tried to collate and<br />
evaluate data on the progress made in<br />
the development of green buildings in<br />
Global Cities. In particular, few report<br />
on the rate of green building adoption,<br />
or the efficiency and performance of<br />
the built environment within these<br />
cities. This paper seeks to compare<br />
the performance of <strong>10</strong> Global Cities<br />
specifically with regards to Green<br />
Buildings.<br />
In order to rank these cities’ green<br />
building performance, a set of criteria<br />
has been developed. The methodology<br />
developed assesses the Global Cities<br />
for their green building performance<br />
across four categories, out of which<br />
three focused on total number of green<br />
2<br />
<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings
uildings, performance and initiatives,<br />
and one category focused on the city’s<br />
green initiatives, which provides a<br />
supportive infrastructure that fosters a<br />
healthy green building movement.<br />
After assessing the <strong>10</strong> Global Cities<br />
for green building performance, the<br />
leading cities were found to be Paris,<br />
followed by Singapore and London.<br />
Sydney, Tokyo and Hong Kong came<br />
respectively in the fourth, fifth and<br />
sixth positions. While New York, Dubai,<br />
Beijing, and Shanghai were the laggards<br />
on this ranking.<br />
When evaluating the Global Cities<br />
on the number of green buildings<br />
and the certification systems in use<br />
(for green buildings), the research<br />
identified Singapore, London and Paris<br />
as the top scorers. These three top<br />
cities are advanced in the adoption<br />
of new and existing green buildings,<br />
and experience a high level of green<br />
building activity.<br />
It should be noted that though Beijing,<br />
Dubai and Shanghai lagged in many<br />
green building indicators compared to<br />
its other Global City peers, these cities<br />
are among the most recent joiners of<br />
the green building movement; when<br />
considering the limited number of<br />
years that Beijing, Dubai and Shanghai<br />
have been working to green their<br />
built stock, the achievements of these<br />
cities are profound, especially when<br />
considering the large number of highly<br />
internationally-certified buildings<br />
currently standing within these cities.<br />
When the Global Cities were ranked<br />
based on the overall performance<br />
and efficiency of the built stock, the<br />
research concluded that Paris and<br />
Singapore are amongst the best<br />
performers; this confirms that the<br />
green building efforts in Singapore and<br />
Paris are palpable, and that the local<br />
green building standards are stringent<br />
enough to produce tangible results.<br />
Although attempting to compare and<br />
rank the numerous green building<br />
policies and codes would pose a<br />
challenge due to their volume and<br />
diversity, Singapore did indeed stand<br />
out as a pioneer in the industry by<br />
putting a comprehensive and bold set<br />
of policies and targets for greening<br />
the city’s built block. As a city that has<br />
committed to greening 80% of its builtstock<br />
by 2030, Singapore stands out as<br />
one of the most ambitious cities on the<br />
list of cities evaluated.<br />
Finally, the assessment of the citylevel<br />
green initiatives established that<br />
both Sydney and Hong Kong have set<br />
higher than average CO 2<br />
reduction<br />
targets amongst the <strong>10</strong> Global Cities,<br />
and have also proven themselves<br />
as they perform noticeably well with<br />
low CO 2<br />
emissions city-wide and high<br />
percentages of waste recycling. Paris,<br />
Singapore, and New York also seem to<br />
perform extremely well on the green<br />
initiatives by implementing appropriate<br />
green solutions for waste and energy<br />
efficiencies.<br />
Thus, for all the above mentioned<br />
reasons, it is important to benchmark<br />
and publish the green building<br />
performance of the largest, most<br />
attractive Global Cities, in order to<br />
evaluate global progress towards<br />
sustainable development, increase<br />
knowledge-sharing, share bestpractices,<br />
and better understand what<br />
is and is not working.<br />

METHODOLOGY AND<br />
MEASUREMENTS<br />
Selecting the Global<br />
Cities in the Ranking<br />
The Global Cities selected for this<br />
white paper were adopted from The<br />
Globalization and World Cities Research<br />
Network (GaWC) approach, which is<br />
a leading academic think-tank that<br />
classifies and researches Global Cities.<br />

As per GaWC, Global Cities are heavily<br />
ranked based on economic factors,<br />
followed by political and cultural<br />
factors. Cities are sorted into three<br />
major categories: Alpha, Beta, and<br />
Gamma. The top <strong>10</strong> Global Cities are<br />
comprised of the Alpha++ and Alpha+<br />
cities, which are vastly more integrated<br />
with the global economy than others.<br />
Due to the similar levels of integration,<br />
pressures, and dynamics of these top<br />
<strong>10</strong> GaWC Global Cities, these were<br />
the Global Cities (outlined in Table 1)<br />
selected to become the basis of this<br />
white paper.<br />

Ranking Cities by Green Building Performance<br />
This paper seeks to compare the performance of these <strong>10</strong> Global Cities specifically with regards to Green Buildings. Each of<br />
these cities were analyzed to assess each city’s green-building policies and targets, adoption of green building certification and<br />
construction projects, and the efficient performance of the city’s built-environment.<br />
In order to rank these cities’ green building performance, a set of criteria was developed. The methodology developed<br />
assesses the Global Cities for their green building performance across four categories, out of which three focus on the<br />
total number of green buildings, performance and initiatives, and one category focuses on the city’s green initiatives and<br />
performance. The data used across all metrics was collected up to the end of year of 2014.<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings 7
Green Building Metrics<br />
1. City-wide Green Building Landscape<br />
This category assesses the total number of green buildings in each city, and<br />
assesses the <strong>10</strong> Global Cities on the number of green buildings, the certifications<br />
given to those buildings, and the availability of green building credentialed<br />
professionals in the city.<br />
The metrics in this category are as follows:<br />
• The % of green buildings versus total number of buildings<br />
• Number of green buildings<br />
• Number of green building credentialed professionals per building<br />
The abovementioned metrics are assessed and analyzed thoroughly in Chapter 4.<br />
2. Green Building Efficiency and<br />
Performance<br />
This category evaluates the current efficiency and<br />
performance of buildings within each of the <strong>10</strong> Global<br />
Cities by measuring CO 2<br />
emissions and energy use<br />
of each city’s built environment. Water consumption<br />
was also evaluated, but not enough reliable data was<br />
available for inclusion.<br />
The metrics in this category are as follows:<br />
• CO 2<br />
emissions from buildings<br />
• CO 2<br />
emissions from buildings per capita<br />
• CO 2<br />
emissions from buildings per GDP<br />
• Energy consumption from buildings<br />
• Energy consumption from buildings per capita<br />
• Energy consumption from buildings per GDP<br />

The abovementioned metrics are assessed and<br />
analyzed thoroughly in Chapter 5.<br />
3. Green Building Policies and Targets<br />
This category identifies available city green building codes and targets, and compares them amongst the <strong>10</strong> Global Cities.<br />
The metrics in this category are as follows:<br />
• Green building code<br />
• City-wide green building targets<br />
The existence of the abovementioned metrics is assessed and discussed in Chapter 6. It should be noted that only the<br />
development and existence of green building codes and targets were assessed for the purpose of this paper; the effectiveness<br />
or resulting impact of these codes and targets being put in place was not compared, as the analysis required is too subjective.<br />
Thus, this chapter discusses the differences between city-wide codes and green building targets, solely for the purpose of<br />
knowledge-sharing.<br />

Green City Metrics<br />
1. Green City Culture and Environment<br />
This category looks at the city-level green initiatives in<br />
each city and evaluates the effectiveness of the adoption<br />
of those initiatives. Because the green building movement<br />
thrives in sustainability-oriented cities which have policies<br />
and leadership that provides an enabling and fostering<br />
environment, it was important to have one set of metrics that<br />
measured the sustainability culture of a city.<br />
The metrics in this category are as follows:<br />
• Climate action plan<br />
• City-wide CO 2<br />
emissions<br />
• City-wide CO 2<br />
emissions per capita<br />
• City-wide CO 2<br />
emissions per GDP<br />
• % of CO 2<br />
emission reduction targets<br />
• % of renewable energy consumed by the city<br />
• % of waste recycled by the city<br />
The abovementioned metrics are assessed and analyzed<br />
thoroughly in Chapter 7.<br />

CHAPTER 2<br />
INTRODUCTION TO<br />
GREEN BUILDINGS<br />
The Green Building Movement<br />
In 1987, the Brundtland<br />
Commission (formerly known<br />
as the World Commission<br />
on the Environment and<br />
Development (WCED) issued the<br />
Brundtland Report at the United<br />
Nations, which first defined<br />
sustainable development as the<br />
“development which meets the<br />
needs of the present without<br />
compromising the ability of future<br />
generations to meet their own<br />
needs.” Therefore, the pursuit<br />
of sustainability requires holistic<br />
thinking in order to understand<br />
how and to what degree each<br />
developmental element affects its<br />
surroundings. By understanding<br />
and measuring these impacts, we<br />
can seek to minimize each effect.<br />
Today, ‘Green Buildings’ have<br />
increasingly become one of<br />
the most growing construction<br />
and design concepts. Owners,<br />
developers, architects, designers<br />
and even consumers are realizing<br />
its importance in sustainability.<br />
When the resource-efficiency<br />
of these green buildings are<br />
coupled with modern designs<br />
and an enhanced quality of life<br />
– the “Business Case for Green<br />
Buildings” quickly become an<br />
attractive one, to both present<br />
and future generations.<br />
The aim of this white paper is to<br />
evaluate Global Cities particularly<br />
on green building performance.<br />
This is particularly important<br />
because green buildings are<br />
one of the most important<br />
elements to the sustainable<br />
development discourse, and the<br />
built environment plays a very<br />
substantial role in cities. In fact,<br />
buildings are the largest energyconsuming<br />
sector worldwide<br />
– accounting for more than 40%<br />
of energy use and responsible<br />
for an estimated 30% of city-wide<br />
emissions.<br />
The focus of this chapter will be<br />
to introduce the concept of green<br />
buildings, highlight the benefits<br />
of building green, and identify<br />
prevailing trends in the green<br />
building movement.<br />

What are Green Buildings?<br />
Green Buildings present itself as an opportunity to generate<br />
tangible results towards sustainable development. The<br />
practice of green buildings drives environmental, economic<br />
and social benefits; this is done by fostering the efficient<br />
operations of buildings through the responsible use of<br />
resources in construction and operations, enhancing<br />
durability, and therefore lowering both operational and longterm<br />
maintenance costs, and often driving up the quality of<br />
life in these built environments.<br />
Green buildings are known to have less negative impacts<br />
on the environment in comparison to standard buildings<br />
of the same size. They are designed, developed, and run by<br />
taking into consideration key elements such as indoor air<br />
quality, efficient resource use (e.g. use of energy, water, and<br />
materials), outdoor views, and synergy with the surrounding<br />
landscape.<br />
Benefits of Building Green<br />
Green buildings play a major role in…<br />
• Decreasing energy use. With the integration of<br />
renewable and zero carbon technologies, green<br />
buildings are made more comfortable, less costly to<br />
operate, and increasingly energy efficient. In essence,<br />
42% less energy is used in a green building than in a<br />
standard building of the same size.<br />
• Reducing water waste. Innovative ways are adopted<br />
in order to achieve water conservation. In fact, statistics<br />
show that 34% less water is wasted in a green building<br />
than in a standard building of the same size.<br />
• Minimizing waste and encouraging reuse. Waste<br />
generation can be minimized through the use of durable<br />
materials and the design of recycling systems. This will<br />
lower waste costs since recycling generally costs less<br />
than getting rid of landfill.<br />
• Conserving natural resources. By maximizing the<br />
use of re-usable, renewable, sustainably managed<br />
materials, it is ensured that buildings make truly low<br />
impacts.<br />
• Boosting employee productivity. Employee<br />
productivity in a green commercial building can be<br />
boosted by 15%, which can strongly affect the attraction<br />
and retention of human capital.<br />
• Supporting a healthier lifestyle and enhancing<br />
well-being. Commercial and residential green<br />
buildings produce efficient heating, ventilating, and<br />
air-conditioning systems to provide high quality indoor<br />
air, and incorporate natural light and views. This creates<br />
an excellent environment for the people residing in or<br />
occupying those buildings, which in turn enhances their<br />
comfort and satisfaction.<br />
“People spend more than 90 percent of<br />
their time indoors — from homes to offices,<br />
schools, retail stores, fitness centers,<br />
health care facilities, and more — which<br />
means that buildings, and everything<br />
in them, can have a profound effect on<br />
human health and well-being. Our built<br />
environment can shape our habits and<br />
choices, regulate our sleep-wake cycle,<br />
drive us toward healthy and unhealthy<br />
choices, and passively influence our health<br />
through the quality of our surroundings.<br />
The WELL Building Standard (WELL)<br />
is the first building standard to focus on<br />
health, and health provides a framework<br />
to incorporate a variety of strategies to<br />
integrate human health and well-being at<br />
the heart of building design, construction<br />
and operations. The standard also has the<br />
potential to transform the way humans<br />
interact with the buildings and spaces they<br />
live in through innovative design.”<br />
– Paul Sciallia, Founder of WELL Institute, U.S.<br />
Central Park Sydney, Australia<br />
When considering just some of the benefits of ‘building<br />
green’, it is easy to see why this is a strategic initiative worth<br />
pursuing for many cities and countries at a government level.<br />
Green cities are also linked to better well-being and greater<br />
popularity, which can enhance a city’s competitiveness,<br />
leading to enhanced tourism and other economic revenues<br />
for a city. As more and more cities are trying to mitigate<br />
their negative footprint on the environment and reduce the<br />
operational costs of running their own cities, a “green-built<br />
environment” becomes increasingly important.<br />

Prevailing Trends in<br />
Green Buildings<br />
The global supply and demand for<br />
green building is on the rise as owners,<br />
engineers, contractors, and tenants<br />
realize the importance of the long-term<br />
market opportunity.<br />
1. There is a major shift in the<br />
expectations stakeholders have<br />
of their own buildings. The level<br />
of education in relation to green<br />
buildings and green materials<br />
from key stakeholders such<br />
as architects, developers, and<br />
end-users is growing. The global<br />
green building materials market is<br />
anticipated to grow at a Compound<br />
Annual Growth Rate (CAGR) of<br />
around 13% during the 2015-2020<br />
period. As already explained,<br />
green buildings are service<br />
providers of enhanced health and<br />
well-being, better environment,<br />
and minimized operating costs.<br />
Consequently, the green building<br />
material market is also expected to<br />
reach USD 234.77 billion by 2019.<br />
2. An increasingly cost-conscious and<br />
financially conservative world has<br />
emerged in the aftermath of the<br />
global financial crisis, coupled with<br />
the recent volatility in the price of<br />
fossil-fuel based energy. In such a<br />
global context, the long-term costsavings<br />
of a green building that<br />
consumes less energy and utilizes<br />
renewable energy is growing<br />
in demand. Accordingly, the<br />
International Energy Agency (IEA)<br />
posits that renewable energy will<br />
represent the largest single source<br />
of electricity growth over the next<br />
five years, and is expected to top<br />
700 gigawatts by 2020 – which is<br />
more than twice Japan’s currently<br />
installed power capacity.<br />
3. Globalization is boosting<br />
sustainable real estate<br />
development worldwide and<br />
aligning regulations. The flow of<br />
economic and intellectual capital<br />
in international trade is helping<br />
to emphasize the adoption of<br />
energy-efficient building practices<br />
and world-class designs; this<br />
has contributed significantly in<br />
achieving public awareness on<br />
environmental concerns and<br />
the need for adopting greener<br />
solutions.<br />
With the increasing demand for green<br />
buildings, developers and clients are<br />
realizing the business, social and<br />
environmental value that green projects<br />
are providing. Global green building<br />
activity is steadily on the rise. In 2009,<br />
only 13% of developers responding to<br />
a survey stated that over 60% of their<br />
firms’ construction projects were a<br />
‘green building’. In 2015, green activity<br />
was four times higher, where over 50%<br />
of all respondents stated that more<br />
than 60% of their firms’ construction<br />
activities were ‘green’ (Figure 2).<br />

“Singapore can certainly be considered a leader in<br />
the field of green building. The city target for 80<br />
per cent of buildings to achieve BCA Green Mark<br />
standards by 2030 is ambitious but achievable, and<br />
the Singapore Green Building Council (SGBC) will<br />
play a key role in delivering this!”<br />

“Singapore and London are the cities which have the<br />
highest green building activity, and Costa Rica, France,<br />
Singapore, and the United Kingdom are the countries that<br />
witness high demand for green building materials”<br />
– Michael Scarpf, Head of Sustainable Construction at Lafarge Holcim, Switzerland<br />
After assessing the ten Global Cities<br />
for green building performance, the<br />
winning city is Paris, followed closely by<br />
Singapore. London rounds out the <strong>Top</strong><br />
3 performing cities.<br />
Paris and Singapore took the top spot<br />
by excelling in all four assessment<br />
categories: City-wide green building<br />
landscape, green building efficiency and<br />
performance, green building policies<br />
and targets, and green city culture and<br />
environment. They were the only cities<br />
that ranked within the <strong>Top</strong> 5 in every<br />
category.<br />
Both Paris and Singapore have strong<br />
building efficiency and performance,<br />
which shows that both local and international<br />
certification standards are<br />
yielding high-performance on green<br />
buildings. London benefits from high<br />
yield of green buildings in the city,<br />
which can be linked to the fact that the<br />
United Kingdom was the first country<br />
ever to introduce a green building<br />
certification system (e.g. BREEAM). Paris<br />
16<br />
<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings<br />
fell just slightly short of Singapore in<br />
the absolute number of green buildings<br />
in the city, and by not setting out a clear<br />
city-wide green building target.<br />
Sydney, Tokyo, and Hong Kong came<br />
respectively in the fourth, fifth and sixth<br />
positions. Although the three cities<br />
performed extremely well on the green<br />
city culture and environment, Sydney<br />
and Hong Kong’s ranks were negatively<br />
affected with the poor results<br />
they achieved on their green building<br />
landscape and performance. Quite<br />
surprisingly, Sydney had the fewest<br />
absolute number of green buildings in<br />
the city, with only 67 green buildings<br />
to date. New York followed as number<br />
7. It has a relatively healthy number<br />
of green buildings constructed within<br />
the city, with 287 (5th) and 320 (4th)<br />
green buildings respectively, due to<br />
having the largest built-environments<br />
in comparison to the other cities, the<br />
percentage of green buildings as per<br />
the total built landscape ranked these<br />
cities as laggards.<br />
Finally, Dubai, Beijing, and Shanghai<br />
were the last cities on the list; this was<br />
an unsurprising result, as these three<br />
cities are amongst the most recent to<br />
join the green building movement. It is<br />
expected that these rankings should<br />
see changes in the future as these<br />
newer ‘green building cities’ are setting<br />
ambitious targets in order to catch up<br />
to other cities’ levels.<br />
Dubai, for example, launched its local<br />
green building standard last among<br />
these <strong>10</strong> Global Cities, in 20<strong>10</strong>, resulting<br />
in fewer locally certified buildings<br />
(8th), and only launched its green<br />
building regulations and specifications<br />
in 2012. Despite the slow start, Dubai<br />
ranks 5th in internationally certified<br />
green buildings (<strong>10</strong>4), and has a total of<br />
147 internationally and locally certified<br />
green buildings erected on its<br />
cityscape. Dubai already ranks 6th for<br />
‘green buildings as a percentage of<br />
total buildings’ and is certainly a city to<br />
watch, as the city seems to work quickly<br />
to recover lost time.
“The UAE is running<br />
behind, compared to its<br />
European counterparts,<br />
but it won’t be like that for<br />
long. We are learning from<br />
others’ experience,<br />
mistakes and best<br />
practices, and adapting<br />
‘old concepts’ to our own<br />
environment and situation.<br />
This is placing the emirate<br />
at a privileged position<br />
where we can focus on the<br />
right aspects from the very<br />
beginning and become a<br />
playground for innovation<br />
and an example for the<br />
other countries in the<br />
region.”<br />

CHAPTER 4<br />
GREEN BUILDING<br />
LANDSCAPE<br />
How Green is the Built<br />
Stock of Global Cities?<br />
Green Buildings<br />
are doubling every<br />
3 years worldwide.<br />
*The absolute number of green buildings: The total<br />
number of green building projects or certification<br />
applications submitted for each city.<br />
Green Buildings are rapidly increasing<br />
– doubling every three years worldwide<br />
as a response to accelerating demand<br />
for sustainability. Green Buildings have<br />
proven to not only minimize the impact<br />
of humankind on the environment but<br />
also to improve social and economic<br />
conditions.<br />
That being the case, cities worldwide<br />
are taking the action to “green” their<br />
built stock and integrate sustainability<br />
principles into the design and planning<br />
process of construction.<br />
Therefore, Global Cities were assessed<br />
on the basis of their green building<br />
landscape, which is defined as the total<br />
number of green buildings and green<br />
building certification systems in use.<br />
The Green Building landscape is an<br />
important dimension to consider since<br />
it shows the overall current uptake of<br />
Green Buildings across our <strong>10</strong> Global<br />
Cities.<br />
London, Singapore and Paris take the<br />
top 3 spots with regards to Green<br />
Building Landscape. This is primarily<br />
due to these three cities scoring in<br />
the top 3 for both *the absolute<br />
number of green buildings and on<br />
the ‘green buildings as a percentage<br />
of total number of buildings’ metrics.<br />
London and Paris particularly scored<br />
high with 68% and 64% of the built<br />
environment comprising green<br />
buildings, respectively; Singapore<br />
followed with 48% of its built landscape<br />
being “green”. Singapore and London,<br />
in particular, also had a very high rate<br />
of absolute number of green buildings<br />
with 2,339 and 1,729, respectively.<br />
Paris also ranked 3rd in absolute<br />
number of green buildings, but scored<br />
relatively low in comparison to the top<br />
2 cities with just 456 green buildings<br />

This chapter gives a brief overview<br />
of sustainability ratings for building<br />
and construction projects, and the<br />
associated certifications systems; and<br />
evaluates cities based on the total<br />
number of green buildings, comparison<br />
of the number of locally and<br />
internationally certified buildings, and<br />
certified credentialed professionals.<br />
Green Building<br />
Certifications<br />
Green Building Certification is an<br />
integral part of the planning and<br />
construction of sustainable buildings.<br />
From the early 1990s, the number<br />
of sustainability tools along with the<br />
number of buildings certified have<br />
increased dramatically worldwide. In<br />
addition to standards for design and<br />
construction of buildings in line with<br />
sustainability goals set by government<br />
authorities, there now exist more than<br />
600 green building certification systems<br />
globally.<br />
These green building ratings or<br />
certification systems are measuring<br />
tools that provide guidelines for the<br />
planning and construction of buildings<br />
while taking into consideration<br />
environmental, economic and social<br />
factors. Moreover, they allow building<br />
owners and developers to confidently<br />
label their buildings as “green” in<br />
a standardized and recognizable<br />
format. The assessment instruments<br />
measure, rate and certify the level<br />
of compliance and performance of<br />
a building with alignment to specific<br />
environmental goals and requirements<br />
set by the standardization organization,<br />
often in line with city-targets, thereby<br />
contributing to the achievement of<br />
those targets.<br />
The first Green Building rating system<br />
in the world was created in the UK in<br />
1990 and named the Building Research<br />
Establishment’s Environmental<br />
Assessment Method (BREEAM). It is<br />
a multi-attribute rating system that<br />
integrates the assessment of the<br />
following key categories: Water, Energy,<br />
Material, Innovation, Management,<br />
Land Use & Ecology, Health & Well-<br />
Being, Pollution, and Waste. Being<br />
highly recognized globally, it has served<br />
as a basis for numerous countryspecific<br />
schemes for rating systems,<br />
such as Hong Kong’s 4-star Green<br />
Building Certification System.<br />
Despite BREEAM being the first green<br />
building rating system, the most widelyused<br />
Green Building rating system<br />
around the globe is the Leadership<br />
in Energy and Environmental Design<br />
(LEED) system, launched in the United<br />
States. It was established by the U.S.<br />
Green Building Council in 2000 for<br />
the sustainability assessment and<br />
rating of green building projects.<br />
LEED assesses projects on the basis<br />
of credits earned across the following<br />
seven categories: Site Selection, Water<br />
Efficiency, Energy and Atmosphere,<br />
Materials and Resources, Indoor<br />
Environmental Quality, Regional Priority,<br />
and Innovation in Design. Credits are<br />
evaluated and eventually result in a<br />
point score compatible with four levels<br />
of LEED certification: Certified, Silver,<br />
Gold, and Platinum.<br />
In order to stimulate the demand for<br />
sustainable buildings and to suit the<br />
individual climatic, cultural and legal<br />
boundary conditions, many countries<br />
have designed and began adopting<br />
their own Green Building rating<br />
systems (Figure 5). In fact, all <strong>10</strong> cities<br />
in our Global Green Building Cities<br />
Ranking have developed their own local<br />
certification. Although each certification<br />
differs in the ratings awarded and<br />
categories assessed, the Green Building<br />
evaluation principle of “awarding credits<br />
for each pillar” is the same.<br />
Today, there exists<br />
more than 600<br />
green building<br />
certification<br />
systems globally.<br />

“Part of the difficulty with both LEED and<br />
BREEAM systems is the one approach across<br />
multiple geographies, climates and cultures. For<br />
example, transportation needs in Texas are very<br />
different from Singapore; water security in Beijing<br />
is different to Manila which requires different<br />
issues to be ranked differently to match local/<br />
regional environment and regulations.”<br />

“All three cities – London, Paris, Singapore – are clearly<br />
advanced in the field of green buildings in terms of<br />
standards and actual certified buildings and landmarks.<br />
They also have a long history of urban planning, research,<br />
regulations and frameworks, which make them examples<br />

WHO’S PERFORMING BETTER IN <strong>THE</strong> TOTAL NUMBER OF GREEN BUILDINGS?<br />
By ranking the Global Cities by total<br />
number of green buildings, Solidiance<br />
has estimated the number of Green<br />
Buildings as a percentage of total<br />
number of buildings in each city (Figure<br />
6). It should be noted that ‘the total<br />
number of buildings’ was derived<br />
from adding up the total number of<br />
skyscrapers and the total number of<br />
high-rise buildings in a city. Due to the<br />
inconsistency of available data, and<br />
green building certifications generally<br />
targeting high-rise buildings firstand-foremost,<br />
low-rise buildings and<br />
other types of buildings (ie. churches,<br />
etc.) were removed from the total<br />
building count for the purposes of this<br />
paper. The total number of Green<br />
Buildings for each city is a sum of<br />
building projects certified by LEED,<br />
BREEAM and local certification<br />
systems.<br />
With regards to the city leading the<br />
Green Buildings chart, London has the<br />
highest percentage of green building<br />
projects (68%) for its total number of<br />
green buildings among the ten Global<br />
Cities chosen. Abreast of London,<br />
Paris also has more than half of the<br />
built stock (64%) certified as ‘Green’.<br />
Singapore, with the concerted efforts<br />
of its government agencies, round<br />
out the top three Global Cities with<br />
48% percent of total number of green<br />
buildings. It is worth noting here that<br />
the fact that the total number of<br />
buildings was limited to two types<br />
of buildings (High-rise buildings 1<br />
and Skyscrapers 2 ), had an impact on<br />
generating such high percentages.<br />

High-rise buildings are defined as a multi-story structure between 35-<strong>10</strong>0 meters tall, or a building of unknown height from 12-39 floors.<br />

While looking at the number of total<br />
buildings, the inconsistency between<br />
the percentage of Green Buildings and<br />
number of total buildings is noticed.<br />
For instance, although it makes sense<br />
for Singapore and London to achieve<br />
high percentages of green buildings<br />
from the built stock since they both<br />
rank first and second respectively<br />
on total number of green buildings<br />
(Figure 8), Paris’ result (Figure 9) can<br />
be questioned as the city does benefit<br />
from having the lowest number of total<br />
buildings (Figure 7). For those that<br />
may claim that Singapore performs<br />
particularly well because it is a relatively<br />
small city, Figure 8 quickly lays those<br />
arguments to rest; Singapore has the<br />
highest number of absolute green<br />
buildings with 2,339 Green Buildings<br />
built to date, outperforming London by<br />
35%.<br />
The disparity between those top<br />
three cities mentioned above and<br />
cities following them is high. As such,<br />
the percentage of Green Buildings in<br />
Shanghai, which comes fourth after<br />
Singapore, is 15%. The fifth city in the<br />
rank is also Chinese: Beijing with 11%<br />
of the total number of green buildings.<br />
Dubai, Tokyo, Sydney, and New York<br />
City come as the next, whereas Hong<br />
Kong complete the list with the lowest<br />
percentage (4%). Having New York City<br />
and Hong Kong achieve the lowest<br />
ratings might be attributed to the fact<br />
that they both have double or triple the<br />
average total number of buildings in the<br />
other cities (Figure 7), knowing that they<br />
come in fourth and fifth place when<br />
ranked based on total number of green<br />
buildings (Figure 8). Another reason<br />
could be the fact that those cities have<br />
been focusing on constructing new<br />
green buildings, without placing much<br />
effort on retrofitting existing buildings.<br />

“The current green building development has been focused on new buildings<br />
but is shifting towards existing buildings. For significant progress, the focus<br />
of stakeholders in Hong Kong should shift from new to existing buildings<br />
which make up the bulk of the building stock. Potentially, more effort can be<br />
made to incentivize sustainability for existing buildings, promote microgrid<br />
/ renewable systems to reduce dependence on coal-powered electricity, and<br />
divert waste from precious landfill space.”<br />

Cities such as London, New York and Hong Kong, which have<br />
adopted their own rating tools in the 1990s, accordingly<br />
have the largest ‘locally certified’ green buildings (Figure 11).<br />

However, Singapore is an exception to this rule. Despite<br />
having launched Green Mark only recently in 2005 – 15 years<br />
after BREEAM (UK) and <strong>10</strong> years after HKBEAM (Hong Kong)<br />
– Singapore’s green building movement has grown rapidly to<br />
include the largest number of locally certified green buildings<br />
in the world (e.g. using Singapore’s Green Mark certification<br />
system).<br />

The ranking based on the number of capita per green building (Figure <strong>10</strong>) did not show a large difference from the ranking<br />
cities based on the number of green buildings. The top three cities for green buildings – Singapore, London, and Paris –<br />
remained in the same position when compared on the population level, i.e. how many people are allocated to each green<br />
building. The only two cities that jumped in the ranking are Dubai and Sydney. This could be due to the fact that both cities<br />
have smaller populations in comparison to Hong Kong, New York, Shanghai, and Beijing. The number of capita per green<br />
building highlights cities that are making notable effort in building design and construction, as well as to create a healthier<br />
environment for inhabitants and workers. The indicator was not included in the methodology, but simply illustrates the ranking<br />
of the cities based on the number of capita per green building.<br />

The number of buildings certified locally<br />
versus those certified internationally<br />
vary slightly across the cities. The<br />
general pattern and trend is for cities<br />
to have a larger number of buildings<br />
certified locally instead of using<br />
international standards (Figure 12<br />
vs Figure 13). The only cities outside<br />
of the trend line are Paris and Dubai<br />
with the larger stock of buildings<br />
certified internationally than with locally<br />
developed standards (Paris using<br />
BREEAM primarily, and Dubai using<br />
LEED).<br />
This can be partially explained here.<br />
In the case of Paris, the small number<br />
of green buildings certified by HQE<br />
certification is believed to be due<br />
to the greater complexity of local<br />
versus international standards. HQE<br />
brings with it a greater number of<br />
requirements, whereas BREEAM and<br />
LEED certifications have far fewer<br />
requirements. Moreover, the BREEAM<br />
certification is less demanding about<br />
the integration of prerequisites, and<br />
processing times for the certification<br />
is more streamlined. One Paris-based<br />
green building professional reported<br />
that LEED and BREEAM certification<br />
applications can be sent via online<br />
platforms without on-site audits;<br />
On the other hand, HQE (Paris’ local<br />
certification system), requires on-site<br />
visits by HQE certifiers on up to 3<br />
separate occasions to conduct various<br />
audits.<br />
In the case of Dubai, it is largely<br />
explained by two factors. Firstly, the<br />
local Estidama Pearl Rating system is<br />
relatively new, having only launched in<br />
20<strong>10</strong>. Secondly, Estidama is a rating<br />
system developed by the Abu Dhabi<br />
Government, for the Emirate of Abu<br />
Dhabi. Abu Dhabi, being the capital<br />
of the United Arab Emirates, made<br />
Estidama available and recommended<br />
its use to all other emirates, including<br />
Dubai – but government regulations<br />
requiring the use of Estidama was only<br />
passed through Abu Dhabi’s policies.<br />
Having been left with the choice,<br />
Dubai continues to use international<br />
standards rather than subscribing to<br />
their neighbouring state’s certification<br />
process.<br />
“It is important to note<br />
that a building can be<br />
sustainable and incorporate<br />
green best practices without<br />
having a certification<br />
behind it. Certifications,<br />
however, are useful tools<br />
for measurement and can<br />
serve as guidelines for best<br />
practice. Nonetheless,<br />
Dubai does not have a<br />
specific certification or<br />
rating systems such as<br />
Estidama in Abu Dhabi, but<br />
the Leadership in Energy<br />
and Environmental Design<br />
(LEED) rating system<br />
is used and recognised<br />
broadly.”<br />

Overall, there are more LEED accredited professionals than those upholding the BREAAM certification<br />
system, and there is a growing trend where locally credentialed professionals are increasing. Tokyo is the<br />
leader both in the total number of professionals, as well as in the normalized metric, which looks at the<br />
total number of credentialed professionals per building (Figure 15).<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings
Conclusion<br />
This chapter has assessed the green<br />
building landscape of each global city by<br />
measuring the number of green buildings,<br />
breaking down those green buildings by<br />
certification system type and evaluating<br />
the number of credentialed professionals<br />
per building. Overall, the trend is an<br />
increasing number of Green Buildings<br />
certified locally instead of internationally,<br />
and cities such as London, Singapore<br />
and Paris rank highest due to both high<br />
number of total green building projects<br />
in the city, and high percentage of green<br />
buildings as per total number of buildings<br />
in the city.<br />

GREEN BUILDING<br />
EFFICIENCY AND<br />
PERFORMANCE<br />
CHAPTER 5<br />
How efficiently do buildings in Global Cities perform?<br />
Buildings are a substantial element<br />
in every city. They are the largest<br />
energy-consuming sector worldwide<br />
– accounting for more than 40% of<br />
energy use and responsible for an<br />
estimated 30% of city-wide emissions.<br />
As a city commits to building green, it is<br />
important for it to set measurable goals<br />
for emissions and energy efficiencies,<br />
water conservation, and waste<br />
management in order to ensure that<br />
building projects are in fact contributing<br />
into enhancing the environment. The<br />
previous chapter evaluated the number<br />
of ‘certified green buildings’ each city<br />
had, and whether they were to a local<br />
or international standard.<br />
This chapter steps in to evaluate,<br />
regardless of the number of certified<br />
green buildings in the city – the overall<br />
efficiency and performance of the built<br />
stock in each city. The efficiency and<br />
performance of the built environment<br />
in each city involved zooming into<br />
2 major interrelated environmental<br />
impacts, namely, CO 2<br />
emissions and<br />
energy use.<br />
Space heating and cooling together<br />
with water heating are estimated to<br />
account for nearly 60% of global energy<br />
consumption of buildings. CO 2<br />
from<br />
energy use is the dominant factor<br />
leading to greenhouse gases emitted<br />
in the buildings sector. Water use was<br />
also an indicator, which was evaluated,<br />
but the lack of data and inconsistency<br />
of city-wide data led to the removal of<br />
this metric.<br />

“Globally, buildings account for 40% of energy consumption and 30% of carbon emissions.<br />
There is a real need for the building industry to undertake greater environmental<br />
responsibility and mitigate the impact of our activities on the environment. Moreover, we<br />
also witness that there is a strong business case for sustainability. This has been proven<br />
as integrating sustainability into our corporate vision and strategy has not only created<br />
long-term business value for CDL, but also for our investors and customers.”<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings
Paris, Sydney, and Singapore take the highest ranking spots with regards to each city’s green building efficiency. This is<br />
primarily due to the three cities not only being very low CO 2<br />
polluting cities in general, but also because they have a very low<br />
percentage of emissions which can be attributed to the city’s built-environment.<br />
How much CO 2<br />
do Cities’ Buildings Emit?<br />
While green building efforts are already underway for all of these Global Cities studied in this report, a majority of the top<br />
Global Cities emit relatively high levels of CO 2<br />
into the environment, with the exception of Paris and Sydney (Figure 17).<br />
Consequently, both cities also perform well in terms of CO 2<br />
emissions as a result of the built environment.<br />

By analyzing the carbon emissions per capita in the top <strong>10</strong> Global Cities (Figure 17); Paris, Sydney, and Singapore maintained<br />
their position as top performers and while Shanghai and Beijing recorded the highest CO 2<br />
emissions from buildings, they<br />
performed slightly better on this dimension, by ranking seventh and eighth on this metric. However, Dubai has a significantly<br />
higher carbon footprint per capita of (11.4MT) as energy consumption is high and its emissions are being spread among a<br />
small population.<br />
Carbon intensity is usually measured in terms of the CO 2<br />
emissions per dollar GDP. A city with low carbon intensity would<br />
mean that it is able to produce each unit of output with less CO 2<br />
emissions. Paris and Sydney remain undefeated as they also<br />
top the scale for carbon intensity of their building stock. Whereas, Singapore and Hong Kong that were in the top 5 for both<br />
CO 2<br />
emissions from buildings and CO 2<br />
emissions per capita, now find themselves ranked just before Shanghai and Beijing.<br />
Singapore has recently announced its goals to reduce emissions intensity by 36% from 2005 levels by 2030 and generally<br />
performs much better when compared as a country considering that it ranked 113th out of 140 countries, according to IEA<br />
Key World Energy Statistics in 2014.<br />
<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings 31
How much Energy do Cities’ Buildings consume?<br />
Paris and Singapore are amongst the best performers in how much energy is consumed from their buildings (Figure 18) – an<br />
indicator of the cities’ level of eco-consciousness and proof that both the local and international green building certifications<br />
used in both these cities are strong certification guidelines which push for greater greener building performance. This, of<br />
course, is the main goal. There may be cities where green building policies are in place, targets are set, local certification<br />
guidelines are created, but none yield strong green building performance in terms of efficiency of resource use and minimal<br />
negative environmental impact. In this light, the performance of the built-landscape in each city is the ultimate end-goal.<br />
Indeed, it seems as though the green building efforts in Singapore and Paris are working together, marking tangible progress,<br />
and are paying off.<br />
Shanghai accounts for the highest level of building energy consumption. New York follows in second place due to relatively<br />
high CO2 emissions from buildings, second highest size of built stock and second lowest percentage of total green buildings.<br />

When evaluating the per capita energy consumption from buildings, New York still comes as the first with the highest energy<br />
use by buildings, further followed by Dubai and Shanghai. Oppositely, Singapore and Tokyo exhibit the lowest building energy<br />
consumption level per capita, whereby the population sizes of the respective cities rank as the 8th and 3rd highest out of<br />
selected top <strong>10</strong> Global Cities (Figure 18).<br />
In part of energy consumption from buildings per GDP, which implies energy efficiency per unit of production, Shanghai and<br />
New York have the highest level, whereas Paris, Tokyo, and Singapore’s buildings consume the lowest level of energy in this<br />
category (Figure 18).<br />
Noticeably, Shanghai and New York do not fare as well in both normalized metrics in comparison to other cities. Under the<br />
City Building Energy Saving Projects Special Support Measures introduced in 2012, Shanghai’s government committed to<br />
provide energy monitoring and management to building projects, and promoting energy saving and green building features.<br />
New York City’s new plan, “One City, Built to Last: Transforming New York City’s Buildings for a Low-Carbon Future” announced<br />
in September 2014 seeks to reduce the carbon footprint of the city’s top greenhouse gases emitters - buildings, both public<br />
and privately owned. These efforts set out by both cities, if executed well and successful will likely materialize into substantially<br />
better results in coming years.<br />

How much Water do Cities’<br />
Buildings consume?<br />
Water consumption from buildings is an important<br />
metric that governments worldwide should take<br />
into consideration. The benefits of enforcing waterefficiency<br />
measures encompass water savings<br />
and achieving sustainability goals. Moreover, such<br />
measures will reduce buildings’ energy costs since<br />
heating water is associated with significant amount<br />
of energy use. Additionally, implementing waterefficient<br />
practices implies achieving green building<br />
certifications thereby fostering healthy green<br />
building movement. Recognizing the importance<br />
of water consumption from buildings, this metric<br />
was however not used in the ranking due to lack<br />
of available data (as only data for New York - 1235<br />
billion litres, Dubai - 267 billion litres, Sydney - <strong>10</strong>1<br />
billion litres, were found). As such, cities should do<br />
more to focus on the portion of water consumed<br />
from buildings, as it is just as important a resource<br />
as energy, if not growing in importance over time.<br />
Annex II includes a graph showcasing annual water<br />
consumption by city.<br />
Conclusion<br />
There are roughly 8 to <strong>10</strong> million new buildings<br />
constructed per annum worldwide, most of<br />
them in developing countries. According to the<br />
International Energy Agency, buildings account<br />
for up to 41% of global energy savings potential<br />
by 2035, compared with the industrial sector<br />
(24%) and the transport sector (21%). Attempts<br />
to improve energy consumption in buildings will<br />
ultimately lead to better levels of CO 2<br />
emissions.<br />
Thus, it is crucial for cities to intensify action<br />
plans aimed at greening the design of the built<br />
environment, so that buildings not only have less<br />
impact on the environment during construction,<br />
but most importantly, operate in a green and<br />
more efficient manner. Greening new buildings at<br />
the design stage is much easier than retrofitting<br />
existing buildings to operate more efficiently. For<br />
these reasons, green buildings are an important<br />
pillar to build more sustainable cities around the<br />
world.<br />

GREEN<br />
BUILDING<br />
POLICIES AND<br />
CHAPTER 6<br />
TARGETS<br />
As covered in the previous chapter,<br />
buildings have wide-ranging direct and<br />
indirect impacts on the environment.<br />
Given the long lifespan of most buildings,<br />
decisions made on the design and<br />
construction of a building during its project<br />
phase will determine its consumption<br />
and impacts over its lifetime. This has<br />
then prompted the inception of green<br />
building standards, certifications, and<br />
rating systems targeted to alleviate a broad<br />
range of environmental issues through<br />
sustainable and greener designs.<br />
For this reason, green building codes<br />
and targets are imperative in a city’s<br />
journey towards greater adoption of<br />
Green Buildings. They act as a guideline<br />
to demonstrate and inform the respective<br />
stakeholders on essential elements to<br />
building green and the crucial steps to<br />
execute such initiatives within a specific<br />
timeframe.<br />

How supportive is your Government towards<br />
Green Buildings?<br />
Singapore is the standout leader in the Green Building Codes and Targets<br />
assessment. While all the Global Cities have outlined city-level green<br />
building codes, only three cities have achieved their green building targets.<br />
Singapore, Beijing and Shanghai are the only cities with both a green<br />
building code and green building targets set-out by the city.<br />
What Policies and Targets are Global Cities<br />
setting directly related to Green Buildings?<br />
Local and regional governments are uniquely positioned to implement<br />
policies that influence the commitments towards sustainability measures in<br />
the building sector, and to encourage its corporate citizens to build green,<br />
and citizens to live green. As such, city-level green building policies were<br />
researched for each city. Two metrics were considered in ranking the cities<br />
on the Green Building Culture dimension – the existence of green building<br />
codes and the existence of green building targets.<br />
Amongst the Global Cities in this study, Tokyo took the chronological lead<br />
with its Green Building Program having been issued in 2002; Tokyo’s Green<br />
Building Program began to take responsibility for the impacts its buildings<br />
had on the environment by requiring that newly built or extended buildings<br />
submit their building environment plans. In 2006, Singapore then launched<br />
its green building policy to spearhead the delivery of green buildings and<br />
concentrated on new buildings and those undergoing major retrofitting. The<br />
newbies in the green building agenda would be Beijing and Shanghai with<br />
recently issued action plans in 2013 and 2014 respectively.<br />

“Tokyo and Singapore are two progressive Asian<br />
cities in terms of green building development.<br />
Tokyo is pretty unique with its cap-and-trade<br />
program covering even large-scale office buildings.<br />
This controls carbon emissions at the source.<br />
Furthermore, development in green building<br />
technologies are at the forefront. Singapore has<br />
mandated energy efficiency standards and energy<br />
audits for existing buildings and provided financial<br />
incentives for the upgrades. The new smart nation<br />
agenda is also interesting with its well thought out<br />

TOKYO<br />
Green Buildings Policy Overview<br />
The submission system of “Building Environment Plan”,<br />
introduced in 2002, was designed in Tokyo to clarify<br />
environment-friendly approaches to buildings and highly<br />
evaluate excellent approaches. The system was introduced<br />
in June 2002 with the aim of creating a market where<br />
environment-friendly and high-quality buildings are<br />
evaluated. It is required for those newly built buildings<br />
or extended and whose total floor area exceeds 5,000<br />
square meters to submit their building environment plans,<br />
which evaluates four points: “streamlining of energy use,”<br />
“appropriate utilization of resources”, “protection of natural<br />
environment” and “mitigation of heat island phenomenon”.<br />
Energy Efficiency policies<br />
The Tokyo Cap-and-Trade Program, launched in 20<strong>10</strong>, is<br />
one of the worldʼs first programs which covers buildings and<br />
facilities in cities such as offices and commercial buildings<br />
and mandates total reduction of CO 2<br />
emissions from large<br />
facilities (accounting for approximately 40% of emissions<br />
from the city’s industrial and commercial sectors). A target to<br />
be achieved by the relevant sectors has been established as<br />
a cap (emission limit) taking into account the 2020 reduction<br />
target for Tokyo as a whole, and a mandatory reduction rate<br />
has been set for each facility based on the cap. Each facility<br />
is obliged to reduce the aggregate total of emissions for the<br />
five years from 20<strong>10</strong> to 2014 (the first planned reduction<br />
period) by 8% or more (for office buildings, etc.) or 6% or<br />
more (for plants, etc.), compared with the amount obtained<br />
by multiplying the baseline annual emission amount by five.<br />
Owners of facilities will reduce CO 2<br />
emissions by introducing<br />
energy-saving measures and renewable energy in their<br />
own buildings, as well as by applying credits such as excess<br />
reductions and renewable energy credits purchased from<br />
other facility owners to their own reductions.<br />
Energy benchmarking / Disclosure<br />
of information<br />
Under the Evaluation and Publication Programme of<br />
Environmental Performance of new buildings, all large newly<br />
constructed buildings in Tokyo are obliged to conduct an<br />
environmental performance evaluation and publish the<br />
building environmental plan, which indicates the evaluation<br />
results. The system requires building owners to adopt<br />
environmentally conscious designs based on guidelines set<br />
down by the government, with the aim of creating a market<br />
where environmentally friendly buildings are highly valued,<br />
through publication and disclosure of their environmental<br />
performance.<br />
Financial incentives<br />
In Tokyo, tax incentives have been made available through<br />
the Energy Saving Promotion scheme targeting small to<br />
medium enterprises. These incentives exempt individuals and<br />
corporations from the enterprise tax when they introduce<br />
energy efficient equipment and renewable energy projects.<br />

SINGAPORE<br />
Green Building Policy<br />
Overview<br />
In 2005, the Singapore Government’s<br />
Building and Construction Authority<br />
(BCA) launched the Green Mark<br />
scheme, a leading green building rating<br />
system, serving as a benchmark tool for<br />
evaluating environmental sustainability<br />
in buildings. The main purpose was<br />
to encourage stakeholders to start<br />
building and living green. Thereafter,<br />
the city launched its first, second, and<br />
third Green Building Masterplans,<br />
which currently focus on driving the<br />
green building agenda by:<br />
1. adopting green building as the<br />
norm for new projects, and<br />
2. greening existing buildings, and<br />
3. focusing on both the hardware and<br />
software of the built environment<br />
(i.e. energy efficiency of buildings<br />
as well as the occupants’ behavior)<br />
4. setting Singapore as the leader<br />
in green building and sustainable<br />
development<br />
In 20<strong>10</strong>, with the launch of the City’s<br />
Sustainability Blueprint, Singapore<br />
set an ambitious target of greening<br />
80% of its building stock by 2030 in<br />
order to accelerate the green building<br />
agenda. By 2014, more than 25% of<br />
the city’s entire built-stock were already<br />
‘greened’.<br />
The target is set to be achieved by<br />
supporting the advancement of green<br />
building within the region, raising<br />
the community’s engagement and<br />
encouraging all stakeholders to get<br />
involved in greening the city, and<br />
sustaining constant monitoring of<br />
energy consumption, and seeking<br />

of people, and the quality of the built<br />
environment.<br />
Energy Efficiency<br />
policies<br />
Demonstrating building energy<br />
performance has become vital in<br />
Singapore to ensure an improved<br />
quality of the built environment.<br />
Existing buildings must comply with<br />
high energy standards and optimally<br />
operate after undergoing retrofit.<br />
Periodical energy efficiency audits<br />
are required, to ensure existing<br />
buildings comply with the minimum<br />
environmental sustainability standards<br />
under the Green Mark scheme.<br />
Energy Benchmarking<br />
/ Disclosure of<br />
information<br />
Singapore acknowledges the<br />
importance of energy and green<br />
building data sharing within the<br />
industry, and ensures transparency<br />
in the performance results. As of<br />
2012, Singapore set requirements for<br />
existing building owners to submit<br />
annual reports regarding their<br />
building information and its energy<br />
consumption through the Building<br />
Energy Submission System (BESS). This<br />
plan is beneficial to many stakeholders:<br />
• It serves the government as it is<br />
used as a way to monitor energy<br />
consumption and energy efficiency<br />
of buildings, thereby providing<br />
insights to BCA in the formulation<br />
of green building policies and<br />
energy performance monitoring<br />
strategies<br />
• It benefits owners and tenants by<br />
creating awareness on the energy<br />
performance of their buildings<br />
and helps them set measureable<br />
targets to improve energy<br />
efficiency of those buildings<br />
• It allows architects, engineers<br />
and other consultants to rethink<br />
their designs and incorporate<br />
best-in-class practices in design<br />
and retrofit of green buildings.<br />
Research and education<br />
communities can also benefit<br />
through data sharing and applied<br />
research to further advance green<br />
building technologies and solutions<br />
for the future<br />
Financial incentives<br />
There has been several Green Mark<br />
Incentive Schemes (GMIS) rolled out<br />
by the Building and Construction<br />
Authority (BCA) over the years, with the<br />
Green Mark Gross Floor Area Incentive<br />
Scheme being the most impactful for<br />
new developments as it drives new<br />
and existing private developments to<br />
undertake substantial energy efficiency<br />
enhancements in efforts to earn high<br />
Green Mark ratings. Other major<br />
schemes in play include its USD 50<br />
million and USD <strong>10</strong>0 million GMIS to<br />
encourage existing building owners<br />
and tenants to improve the energy<br />
consumption of their buildings and<br />
premises. Moreover, the Building<br />
Retrofit Energy Efficiency Financing<br />
(BREEF) Scheme financing programme<br />
introduced in collaboration with several<br />
Financial Institutions provide support to<br />
its building owners in overcoming the<br />
high upfront cost of carrying out energy<br />
efficiency retrofits.
PARIS<br />
Green Building Policy Overview<br />
Thirty large businesses have signed Paris Climate Action<br />
Charter initiated by the city authorities thereby undertaking<br />
steps to realize aims of Climate-Energy Plan. Under this<br />
charter, the Paris District Heating Company supplying 1/3 of<br />
public heating launched a programme to reduce pollution<br />
and promote renewable energies. By 2020, more than<br />
500,000 tonnes of CO 2<br />
will be reduced in the city every year.<br />
Built on the initiative of the City of Paris to assist in achieving<br />
the goals of the France Climate Action Plan, the Paris Climate<br />
Agency has been providing the support to the stakeholders’<br />
projects on green action. For instance, Lumo, a platform for<br />
responsible investment in renewable energy projects, has<br />
been developed in partnership with local authorities.<br />
Paris has also started the plan of one thousand buildings’<br />
energy renovation set to complete by 2020. This involves<br />
supporting building owners in their efforts to reduce<br />
Greenhouse Gas Emissions (GHG) and energy consumption<br />
through trainings spreading the word about ways to reach<br />
greener buildings while taking into consideration affordability.<br />
Moreover, under the environmental law approved by French<br />
parliament on March 19, 2015, the rooftops on all new<br />
buildings built in commercial zones in Paris must now be<br />
partially covered in plants or solar panels aiming to reduce<br />
heat and cooling energy consumption by buildings.<br />
In 2012, Paris introduced regional energy and air quality<br />
guidelines aligned with three following goals of Energy Action<br />
Plan for 2020:<br />
• Improve buildings’ energy efficiency, with a target<br />
of doubling the pace of non-residential building<br />
refurbishment and tripling it for residential buildings<br />
• Develop district heating powered by renewable and<br />
recovered energies, with a target of increasing the<br />
number of connected equivalent housing units by 40%<br />
• Reduce GHG emissions from road traffic by 20% in<br />
combination with a significant reduction in air pollutants<br />
Energy Benchmarking / Disclosure<br />
of information<br />
Every five years since 2004, the city authorities conduct<br />
GHG inventory and energy consumption assessments<br />
of government and community. In addition, an annual<br />
assessment of the implementation of the climate action<br />
plan is realized. The data on performance and practical<br />
achievement along with budget spent is published in the<br />
“Bleu Climat” report every year.<br />
Financial incentives<br />
Every year the City of Paris invests around USD 44 million<br />
in retrofitting residential buildings. Paris also supports<br />
green initiatives providing loans to green entrepreneurial<br />
companies and low rent fee spaces to install green activities.<br />

NEW YORK<br />
Green Building Policy<br />
Overview<br />
The City of New York was one of the<br />
first jurisdictions to concentrate on<br />
improving energy efficiency in existing<br />
buildings, and it now leads innovation<br />
in Green Building.<br />
With energy efficiency and conservation<br />
driving its main agenda, New York City<br />
(NYC) established an independent,<br />
non-profit financial corporation called<br />
the New York City Energy Conservation<br />
Code (NYCEEC) in 20<strong>10</strong> – to assist<br />
the city in implementing its Greener,<br />
Greater Buildings Plan (GGBP) while<br />
advancing the goals of PlaNYC.<br />
The GGBP, introduced in December<br />
2009, addresses benchmarking, energy<br />
audits and retro-commissioning, as well<br />
as the adoption of a new energy code,<br />
all working towards increased energy<br />
efficiency for the city. Local Law 86<br />
(LL 86), the local Green Building Law,<br />
establishes a set of standards for public<br />
design and construction projects.<br />
Energy Efficiency<br />
policies<br />
With ‘One City: Built to Last’, the city<br />
will target every public and private<br />
building that needs significant energy<br />
upgrades. It is an all-inclusive <strong>10</strong>-year<br />
plan targeted to improve the energy<br />
efficiency of the NYC’s buildings, and<br />
sets an ambitious goal to reduce the<br />
city’s building emissions by 30% by<br />
2025. To achieve this goal, the City<br />
intends to:<br />
1. Complete efficiency improvements<br />
in every City-owned building that<br />
has significant energy use and<br />
install <strong>10</strong>0 MW of onsite renewable<br />
power.<br />
2. Cost-effectively build highly<br />
efficient buildings, looking to<br />
Passive House, carbon neutral, or<br />
“zero net energy” strategies.<br />
3. Develop interim energy<br />
performance targets for existing<br />
buildings to be achieved through<br />
voluntary reductions and new<br />
regulations.<br />
Other measures such as LL86<br />
requires that projects (i.e. new<br />
constructions, additions and substantial<br />
reconstructions) receiving more than<br />
a specified amount of city funding<br />
achieve a LEED rating level of certified<br />
or Silver and/or reductions in energy<br />
cost and potable water use.<br />
Energy Benchmarking<br />
/ Disclosure of<br />
information<br />
The GGBP requires large commercial<br />
and multifamily buildings to benchmark<br />
their energy and water consumption<br />
with Energy Star where the data will<br />
be posted online by the city. Failure to<br />
comply will warrant a fine. Local Law<br />
87, also part of the GGBP, mandates<br />
that buildings over 50,000 gross square<br />
feet undergo periodic energy audit and<br />
retro commissioning measures.<br />
Financial incentives<br />
New York City is one of the national<br />
leaders in terms of providing incentives<br />
for energy efficiency, at approximately<br />
USD 250mil p.a. covering a variety of<br />
programs, including direct incentives<br />
for energy reduction and market<br />
transformation. Local utilities and the<br />
New York State Energy Research and<br />
Development Authority administer such<br />
programs.<br />
In addition, the New York State Green<br />
Building Tax Credit provides USD 25<br />
million in income tax credits over<br />
a nine-year period for owners and<br />
tenants of buildings, which meet<br />
energy, indoor air quality, materials,<br />
commissioning, water conservation,<br />
appliance, and size criteria. Low<br />
interest loans (i.e. 4% below market<br />
rates) are provided for energy efficiency<br />
measures and building materials<br />
that meet New York green building<br />
standards.<br />

Green Building Policy Overview<br />
The Building Design to Foster a Quality and Sustainable Built<br />
Environment (BDF QSBE) was introduced in April 2011 for<br />
all new building plans to promote energy efficiency, urban<br />
livability, building maintenance, environmental conservation<br />
and green features in buildings. BDF QSBE requires that<br />
all new buildings undergo the Hong Kong Green Building<br />
Council BEAM Plus assessment and designed in accordance<br />
with a package of green building measures to receive<br />
concessions for additional gross floor area (GFA).<br />
Launched in March 2013, HK3030 campaign targets a<br />
reduction of 52% in absolute electricity consumption<br />
compared to a BAU scenario, which essentially reduces 30%<br />
of the absolute building electricity consumption by 2030, as<br />
compared to 2005 levels. For government buildings, a 5%<br />
electricity reduction target by 2020 (2014 as base) is set.<br />
Energy Efficiency policies<br />
In October 1998, the Building Energy Codes laid out<br />
compliance standards for which subsequently required<br />
mandatory compliance with the enactment of Buildings<br />
Energy Efficiency Ordinance (BEEO). The BEEO requires that<br />
developers or building owners of newly constructed buildings<br />
ensure that building services installation comply with the<br />
design standards of the BEC.<br />
Energy Benchmarking / Disclosure<br />
of information<br />
The BEEO enforced a statutory requirement to perform<br />
energy audits every <strong>10</strong> years and that the first round of<br />
audits to be completed by September 2016 on owners of<br />
commercial and composite buildings. Further requirements<br />
mandate that the Energy Audit Form, which contains the<br />
annual energy utilization index of the past 12-month period<br />
be exhibited in a conspicuous position at the main entrance<br />
of the building.<br />
Financial incentives<br />
BEEFS, one of the largest government-funded energy saving<br />
schemes in the world provided USD 450mil to stimulate<br />
private sector building owners to invest in improvements.<br />
New matching schemes in operation from 2014 to 2018 by 2<br />
major electric companies will provide an estimated USD <strong>10</strong>0<br />
million to support energy saving projects.<br />
With BDF QSBE, building owners are incentivized to<br />
incorporate specific features such as sustainable building<br />
design guidelines on building separation, building setback,<br />
site coverage of greenery and energy efficiency of buildings in<br />
order to obtain a GFA concession of up to <strong>10</strong>%.<br />

DUBAI<br />
Green Building Policy Overview<br />
In 2012, Dubai Municipality (DM) launched the Green Building<br />
Regulations and Specifications code for public buildings and<br />
later in 2014 for private commercial buildings. The purpose<br />
of the code is to increase resource-efficiency of buildings<br />
and to support Dubai’s Strategic Plan. The green buildings<br />
in Dubai are also assessed in accordance with the Estidama<br />
Pearl Rating System. Although this system is designed by and<br />
tailored to the Emirate of Abu Dhabi (the country’s capital<br />
and home to the federal government), its principles and<br />
indicators are applicable to other Emirates such as Dubai as<br />
well.<br />
As per “greening” the existing old-aged built stock initiative,<br />
the local Green Building Council introduced the Technical<br />
Guidelines for Retrofitting Existing Buildings in 2015, which<br />
implies refurbishment works with the purpose of increasing<br />
energy and water efficiency.<br />
In terms of the city’s Green Building achievements, Dubai has<br />
managed to – in a short period of time - green 8.4% of the<br />
city’s built stock via international rating and certification tools<br />
as well as the local Estidama Pearl Rating system. The city also<br />
has the world’s largest LEED Platinum government building<br />

• Encourages government-invested and public buildings sized >20,000 m 2 to follow the requirement of China Green<br />
Building Standards 2-Star or above.<br />
• Promotes the development of green eco-demonstration areas such as the Future Science and Technology City.<br />
During the period of the 12th Five Year Plan from 2011 to 2015, Beijing plans to construct at least ten ecological<br />
demonstration zones. All buildings within these zones must meet a minimum 1-star certification; with at least 40% of the<br />
buildings achieving a 2-star level or higher.<br />
Financial incentives<br />
The Chaoyang District in Beijing recently included LEED certifications to their existing incentive structure in which LEED Gold<br />
buildings will receive a one-time incentive of USD1.53/square meter of certified space, and LEED Platinum buildings will receive<br />
USD 3.06/square meter of certified space. Subsidies are also offered for 2-star and 3-star certified project amounting to USD<br />
3.44/square meter and USD6.12/square meter respectively. For both 1-star and 2-Star certifications in the aspects of design<br />
and operation, subsidies ranging from USD 1.2 thousand to USD 1.5 thousand are offered per project.<br />

SHANGHAI<br />
Green Building Policy Overview<br />
In 2011, the City of Shanghai was the first city in China<br />
to launch a “green standard” in construction to facilitate<br />
the promotion of energy efficiency and is actively working<br />
towards China’s 2020 aim to green at least 30% of new<br />
buildings constructed from 2012. Introduced in mid 2014,<br />
the Shanghai Municipality 3-Year Green Building Action Plan<br />
(2014-2016), in principal requires:<br />
• New civil buildings be constructed in accordance with<br />
green building standards 1 Star and above, and<br />
• Large public and government office buildings sized<br />
above 20,000 square meters to be constructed in<br />
accordance with green building standards 2-Star and<br />
above.<br />
Enforced on all new and existing buildings, initiatives such<br />
as Special Planning Shanghai’s Green Building and Eco-City<br />
comprises of government policies, plans and regulations, and<br />
professional guidance.<br />
Energy Efficiency policies<br />
The various energy management policies in place include:<br />
• Shanghai City Building Energy Saving Projects Special<br />
Support Measures (2012) – inclusive of ways the<br />
government will provide energy monitoring and<br />
management to building projects, and offered subsidies<br />
in effort to promote energy saving, green building<br />
features.<br />
• Regulation of Shanghai Building Energy Conservation<br />
(2011) encompasses the most comprehensive energy<br />
policies for the building sector in Shanghai.<br />
• Shanghai Energy-Efficient Building Design Standards<br />
guide encourages contractors to use energy-efficient<br />
materials and to adopt energy saving technologies for<br />
heating, cooling, ventilating, and lighting public buildings.<br />
Energy Benchmarking / Disclosure<br />
of information<br />
Systematic monitoring of green building standards is in place<br />
and energy audits are conducted. In addition, public buildings<br />
are required to implement sub-metering, and monitor<br />
and report its energy consumption data to the Municipal<br />
Construction and Transportation Committee.<br />
Financial incentives<br />
The Shanghai government will be investing up to<br />
approximately USD 1.29 million in subsidies which will be<br />
awarded to buildings with green features including China<br />
Green Building Label certified projects, prefabricated<br />
projects, new and existing buildings with high energy<br />
efficiency, on site renewable energy, amongst many.<br />

Conclusion<br />
This chapter has laid out the major, notable policies/codes, targets, and incentives<br />
developed by the <strong>10</strong> cities in our study. Each city has established its own targets<br />
and an accompanying policy or action plan to serve as guiding principles to<br />
support and grow its number of green buildings and reduce its environmental<br />
footprints.<br />
Tokyo began its green building journey in 2002 (the earliest of all <strong>10</strong> cities) and<br />
introduced a ‘Cap-and-Trade Program’, the world’s first carbon trading scheme, in<br />
20<strong>10</strong>. Today, the program is being replicated in neighbouring Asian governments<br />
and continues to spark interest in surrounding Metropolitan areas. Despite its<br />
early start, Tokyo’s green building landscape and performance rank below cities<br />
such as London, Singapore and Paris. Findings from ‘An Analysis of Comprehensive<br />
Effectiveness of Tokyo’s Climate Policies’ (Kamei, 2013) put forward certain reasons<br />
- generally, little information have been provided to building owners to employ<br />
energy-efficiency equipment and latest green technologies for their buildings,<br />
there has been a lack in subsidies for building owners to upgrade the facilities and<br />
while CO 2<br />
emissions from a building heavily relies on the energy use of tenants,<br />
this policy centers around building owners.<br />
New York has numerous initiatives enabling its green building movement but<br />
its GGBP has become one of the most comprehensive sets of energy efficiency<br />
policies in the United States, and targets the City’s largest existing buildings.<br />
However, the City is also trailing behind on its green building landscape and<br />
<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings 49
Singapore’s success in its green<br />
building agenda can be attributed<br />
to being a pioneer in the industry<br />
coupled with having put in place a set<br />
of comprehensive and bold policies<br />
for the construction of its buildings.<br />
By 2008, the City amended its<br />
Building Control Act, requiring all new<br />
construction and retrofits of existing<br />
buildings to achieve, at minimum, a<br />
Certified rating under the Green Mark<br />
Scheme. It’s Green Building Masterplan<br />
is comprised of policy instruments<br />
designed to enforce minimum<br />
environmental standards for building<br />
codes, stimulate the private sectors,<br />
promote research and development<br />
in environmental sustainability and<br />
grow Singapore’s appetite for green<br />
buildings.<br />
performance possibly because, like<br />
Tokyo, it is one of the largest and oldest<br />
mega-cities in our list of Global Cities;<br />
in addition, most of NYC’s initiatives<br />
have only targeted large buildings,<br />
casting aside ~50% of the city’s floor<br />
space – mainly residences and small<br />
business, where opportunities for<br />
energy reduction are also plentiful.<br />
Also, beyond meeting the NYC Energy<br />
Conservation Code requirements in<br />
force at the time of renovations by<br />
2025, there is no obligation to make<br />
any capital improvements based on<br />
the energy information generated.<br />
With that said, ‘One City: Built to Last’,<br />
a comprehensive <strong>10</strong>-year roadmap<br />
spanning 2015 to 2025 aims to target<br />
every public and private building<br />
requiring energy upgrades and<br />
might be just what the City needs to<br />
instigate a significant change in its<br />
environmental impacts.<br />
While Beijing and Shanghai newly<br />
joined the green building movement<br />
in 2013 and 2014, their results are<br />
already apparent in their total green<br />
building area. In Q1 2015, both cities<br />
were the top 2 out of <strong>10</strong> cities in<br />
terms of green building area (nearly<br />
20 million sq. m.), surpassing major US<br />
cities such as Chicago, New York and<br />
Washington D.C. They also managed to<br />
achieve a higher-rating (LEED and local<br />
certifications) green building area of 14<br />
million sq. m. taking up approximately<br />
75% of total green building area.<br />
Attempting to compare and rank the<br />
numerous codes, incentives and targets<br />
across cities would pose a challenge<br />
due to the volume and diversity of such<br />
initiatives. However, the effectiveness<br />
of policies and targets can be linked to<br />
and determined by the performance of<br />
the city in terms of the rate of adoption<br />
of green buildings (i.e. Green Building<br />
landscape), and the performance of<br />
green buildings in the city (i.e. Green<br />
Building performance and efficiency),<br />
and the performance of the city on the<br />
overall green level (i.e. Green Culture<br />
and Environment) as respectively<br />
described in previous chapters, and the<br />
following one.<br />

CHAPTER 7<br />
GREEN CITY<br />
CULTURE &<br />
ENVIRONMENT<br />
Do Global Cities enable a<br />
Green Building Agenda by<br />
Fostering a “Green City”<br />
Environment?<br />
Sustainability is at the core of economic,<br />
social and environmental initiatives<br />
worldwide. Green buildings result in<br />
energy and water efficiency and saving,<br />
while further decreasing the impact on<br />
the environment. This, in turn, fosters the<br />
productivity, creativity and innovation in the<br />
cities’ community. As such, the community<br />
with developed green city culture and<br />
environment will further streamline the<br />
sustainability efforts to increase the total<br />
number of green buildings. As a result, it is<br />
a circle where the sustainable environment<br />
and communities’ commitment to it are<br />
intertwined, the latter serving as the driving<br />
force.<br />
Thus, this chapter looks at whether cities<br />
adopt a climate action plan, have set targets<br />
to reduce their CO 2<br />
emissions, and evaluates<br />
whether they are actively addressing waste<br />
and energy by implementing green solutions<br />
such as waste recycling and renewable<br />
energy technologies.<br />

In ranking of this category, the ‘usual<br />
suspects’ in global green city rankings come<br />
to the forefront. Sydney, Paris and New York<br />
take the top 3 spots, and Singapore is just<br />
shy in 4th place.<br />
Once metrics are looked at individually, the<br />
top performers are somewhat scattered.<br />
Sydney and Paris, in particular perform<br />
well in terms of having single digit citywide<br />
CO 2<br />
emissions, with 6 and 7 million<br />
metric tonnes, respectively. New York is<br />
the standout renewable energy performer<br />
with the 17% of the city’s energy coming<br />
from renewable sources. Sydney is the<br />
clear winner when it comes to recycling;<br />
Sydney recycles nearly 70% of the city’s<br />
waste. Finally, surprisingly, the 3 Chinese<br />
cities ranked in the top 3 when it came to<br />
CO 2<br />
reduction targets, aiming to reduce CO 2<br />
emissions by over 3% per annum.<br />

Climate Action Plan<br />
A Climate Action Plan is a set of strategies<br />
aiming to embark upon sustainability and<br />
climate change action. Its primary goal is to<br />
guide the efforts and keep the city on the<br />
path of carbon emissions reduction. Since<br />
such goal means shifting from a fundamental<br />
patterns of urban development, buildings<br />
and consumption, the Climate Action Plan<br />
goes far beyond CO 2<br />
reduction.<br />
Actions to improve a city’s building energy<br />
and water use efficiency ultimately leads<br />
to a city’s greater resilience to the impacts<br />
of climate change. The top <strong>10</strong> Global Cities<br />
listed have each outlined the steps of the<br />
plan such as renewable energy use in<br />
power plants, transportation, and buildings,<br />
reduction of energy waste and greenhouse<br />
gases.<br />
Mode Gakuen Cocoon Tower, Tokyo, Japan<br />
Chinese cities Beijing and Shanghai, despite<br />
the absence of Climate Action Plans set,<br />
have adopted policies in line with the goals<br />
of Climate Action Plan. For instance, Beijing<br />
has set Clean Air Action plan, which tackles<br />
transportations’ carbon emissions. The city<br />
will also shut down 2,500 polluting firms in<br />
2016 aiming to shift from coal consumption<br />
to clean energy.<br />

CO 2<br />
emissions<br />
Global CO 2<br />
emissions mainly reflect the world’s fossil energy consumption and make up a substantial<br />
65% of total greenhouse gas emissions. Plotting out the emissions of the <strong>10</strong> Global Cities in Figure 23,<br />
Beijing and Shanghai rank the lowest due to the cities’ significant contribution of CO 2<br />
emissions, while<br />
Sydney and Paris take the lead with much lower quantity of emissions – approximately 6 and 7 million MT<br />
in 2014/15.<br />

By normalizing the CO 2<br />
emissions per capita and per GDP (Figure 23), Sydney, and Paris remain as top<br />
performers. However, while New York and Tokyo show more positive performance after normalization,<br />
Hong Kong, Singapore, and Dubai exhibit poor per capita performance in comparison with the other<br />
cities.<br />
According to IPCC, to limit global warming to 2°C as agreed on by the world’s governments at a 2009<br />
meeting in Copenhagen, global GHG will need to be reduced by 40% to 70% by 2050. In response, the<br />
top <strong>10</strong> Global Cities have pledged to reduce, or limit the growth of emissions by setting respective CO 2<br />
reduction targets to be achieved within the coming years (Figure 24).<br />

To address the high levels of city-wide emissions in Beijing and Shanghai, the cities established relatively high targets to be<br />
achieved within a 5- to <strong>10</strong>-year period amounting to more than 3.5% per annum. At the other end of the scale are Singapore,<br />
New York and London with reduction targets of 1% p.a. and lower.<br />
Waste recycling<br />
Waste recycling is becoming crucial for sustaining the environment and avoiding extra pollution of the city. It helps in saving<br />
resources and energy, generating revenues and minimizing landfill costs. Governmental institutions, private businesses, and<br />
residents are all responsible of keeping their surrounding clean with minimal effect on the environment. This is why many<br />
cities are proposing new initiatives concerning waste recycling and management.<br />
For the purpose of our study, current performance of the <strong>10</strong> Global Cities on waste recycling was assessed to identify which<br />
cities are taking action on this matter.<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings
Sydney and Singapore topped the list by achieving respectively high percentages of recycled waste (68%<br />
& 60%). In fact, Sydney set an interim waste strategy which purpose is to provide sustainable waste and<br />
recycling services through 2030. It includes six key focus areas: (1) producing less waste, (2) maximizing<br />
resource recovery, (3) having green infrastructure integration, (4) reducing greenhouse emissions, (5)<br />
introducing solutions for waste problems, and (6) cleaning the streets.<br />
As for Singapore, the city is following an integrated solid waste management system that concentrates<br />
on waste reduction, reuse and recycling. Waste-to-energy incineration plants are also adopted to reduce<br />
waste volume in the most efficient way.<br />
In comparison, the cities of Shanghai and Beijing scored the least among the <strong>10</strong> cities as they don’t show<br />
a clear plan for addressing waste recycling and reduction, and do not adopt a city-specific climate action<br />
plan.<br />
Consumption of Renewable Energy<br />
Renewable energy technologies are clean sources of energy which have a minimized impact on the<br />
environment than any traditional energy source. They are most of the times part of any city’s climate<br />
action plan, and considered as a good practice to reduce CO 2<br />
emissions. The <strong>10</strong> Global Cities were<br />
evaluated based on their consumption of renewable energy and results are shown in Figure 26.<br />

With constant and close coordination between the public and the private sectors, New York City<br />
managed to achieve the highest score for renewable energy consumption. Solar, wind, biomass and<br />
hydro are the renewable sources with the greatest short-term potential to provide significant amounts of<br />
energy for New York.<br />
Sydney is also putting lots of effort into adopting renewable energy technologies through its city master<br />
plan. In Beijing and Shanghai, efforts in renewable energy also involve heavy investments in wind farms.<br />
On the opposite side, Hong Kong and Dubai still have a long way to go, where the two cities’ use of<br />
renewable energy is very low. Recently, Dubai have committed to provide 5 percent of its energy demand<br />
from solar power by 2030.<br />
Waste Water Recycling<br />
Wastewater recycling is also worthwhile to look at when evaluating the city’s green culture. Wastewater<br />
can be an important and valuable source of alternative water. However, it demands appropriate<br />
management and processing before it can be reused due to contaminants. The given metric was not<br />
included in the ranking because the publicly available data is only at country level.<br />

Conclusion<br />
City-level green initiatives are essential<br />
for measuring the sustainability culture<br />
of the city, and how it fosters a green<br />
environment – which directly and<br />
indirectly enables the green building<br />
agenda. The top <strong>10</strong> Global Cities have<br />
adopted various policies and regulations<br />
in line with the goals of their individual<br />
Climate Action Plans. To reduce CO 2<br />
emissions, all <strong>10</strong> Global Cities have set<br />
targets to achieve within a period of time.<br />
London and New York started their CO 2<br />
reduction plans in the 1990s, which also<br />
explains how both do well on green city<br />
initiatives.<br />
New York performs particularly well in<br />
renewable energy consumption (#1) and<br />
London performs above average when<br />
ranked in their efforts for waste recycling<br />
and renewable energy consumption.<br />
Both Sydney and Hong Kong have set<br />
higher than average CO 2<br />
reduction<br />
targets amongst the <strong>10</strong> cities, and have<br />
also proven themselves as they perform<br />
noticeably well with low levels of city-wide<br />
CO 2<br />
emissions and high percentages<br />
of waste recycling. Cities like Beijing,<br />
Dubai, and Shanghai have newly joined<br />
the movement (in 20<strong>10</strong>), which explains<br />
why the three lag behind on the waste<br />
recycling metric, and for Dubai on the<br />
renewable energy consumption.<br />
“In SE Asia we see several ASEAN initiatives that will help<br />
in harmonizing policies which ideally approach similar<br />
corporate levels as the European Union. Renewable energy is<br />
becoming a larger part of the energy profile for cities. In the<br />
United States the U.S. Department of Energy’s (DOE) has<br />
implemented a Cities Leading through Energy Analysis and<br />
Planning (Cities-LEAP) program which is led by the National<br />
Renewable Energy Laboratory (NREL). This program looks at<br />
the Energy Profiles of 23,400+ U.S. cities and is focused on<br />
promoting more efficiency of the use of energy in cities.”<br />

Conclusion<br />
Green buildings presents itself globally<br />
as an opportunity for generating<br />
sustainable growth.<br />
When considering just some of the<br />
benefits of building green, it is easy<br />
to see why this is a strategic initiative<br />
worth pursuing for many cities and<br />
countries, which are trying to mitigate<br />
their negative footprint on the<br />
environment, reduce the operational<br />
costs of these cities, and sometimes<br />
add additional sources of revenue (e.g.<br />
eco-tourism, competitiveness, green<br />
job creation, etc.).<br />
This white paper compared the<br />
performance of ten Global Cities –<br />
Beijing, Dubai, Hong Kong, London,<br />
New York, Paris, Shanghai, Singapore,<br />
Sydney, and Tokyo – with regards to<br />
Green Buildings. Each of the cities<br />
were analyzed to assess each city’s<br />
green building policies and targets,<br />
adoption of green building certification<br />
and construction projects, and the<br />
efficient performance of the city’s built<br />
environment.<br />
The purpose of the paper was to<br />
benchmark and publish the green<br />
building performance of these<br />
Global Cities, in order to contribute<br />
to knowledge-sharing, reveal bestpractices,<br />
and better understand what<br />
is best working for cities on the global<br />
green building stage.<br />
This white paper has found Paris to<br />
be top ranking (1st) in its pursuit of<br />
developing a leading Green Building<br />
city. Paris is indeed excelling on Green<br />
Building efficiency and performance;<br />
this can be clearly observed from<br />
having the lowest CO 2<br />
emissions and<br />
energy consumption from buildings.<br />
Despite having normalized most of<br />
the metrics in this report by GDP and<br />
population, the fact that the city’s<br />
land area and population being the<br />
smallest and the GDP being the 4th<br />
largest among the <strong>10</strong> cities gives Paris<br />
an advantage. Small cities emit less<br />
CO 2<br />
and consume relatively less energy<br />
than other big cities, and tend to be<br />
more efficient.<br />
Paris also was the second city to<br />
perform well on the Green Culture<br />
and Environment dimension<br />
following Sydney. The city showed<br />
positive performance on city-wide<br />
CO 2<br />
emissions (2nd), city-wide CO 2<br />
emissions per capita (2nd), and<br />
city-wide CO 2<br />
emissions per GDP<br />
(1st). In fact, Paris clearly puts (1)<br />
GHG emissions reduction, (2) Energy<br />
consumption reduction, and (3)<br />
Renewable energy consumption at the<br />
center of its climate action plan.<br />
Unlike many cities in our ranking, Paris<br />
seems to focus all of its efforts on<br />
achieving the set goals by encouraging<br />
green urban planning, implementing<br />
strict regulations on buildings,<br />
and providing safe energy supply.<br />
Interestingly, Parisian developers seem<br />
to have a strong preference for the<br />
international BREEAM certification<br />
over the city’s local HQE green building<br />
standard for this very reason: HQE<br />
seemed to be more stringent, and<br />
more challenging to achieve.<br />
Instead of setting a target of greening<br />
a percent of its built stock in the future<br />
(i.e. focusing on the numbers), Paris<br />
has focused its effort on the endresult<br />
– setting quantifiable targets<br />
for energy efficiency and building<br />
performance. Many cities in our ranking<br />
still focus on activity-based goals (ie.<br />
number of green building certifications<br />
issued), rather than setting city-wide<br />
performance-based goals (% reduction<br />
of energy consumption by buildings).<br />
Singapore followed Paris, and ranked<br />
second overall. The city excels in its<br />
green building landscape, and green<br />
building policies and targets. In fact,<br />
both local and international certification<br />
standards in Singapore are yielding<br />
high-performance in green building,<br />
and proving to be efficient. Singapore<br />
has rapidly joined the green building<br />
movement to reach the largest number<br />
of certified green buildings – using both<br />
global (LEED and BREEAM) and local<br />
(Green Mark) certification systems,<br />
with over 2300 green buildings on its<br />
cityscape to date.<br />
Beyond the outstanding number of<br />
certified green buildings on Singapore’s<br />
skyline, the overall efficiency and<br />
performance of the built stock in<br />
Singapore is also performing strongly,<br />
indicating the city’s commitment to<br />
sustainable performance. Singapore,<br />
as a government, is clearly ecoconscious<br />
and committed to pushing<br />
and monitoring the green building<br />
agenda; this is illustrated by the strict<br />
72<br />
<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings
action plan being implemented which<br />
aims to green 80% of Singapore’s total<br />
built stock by 2030. The city is already<br />
encouraging all stakeholders to get<br />
involved in greening the city, monitoring<br />
energy consumption, and seeking<br />
solutions for enhancing the well-being<br />
of people, and the quality of the built<br />
stock.<br />
It is initially surprising that New York<br />
does not fare as well as expected on<br />
the Green Building metrics. Although<br />
the city possesses the 2nd highest<br />
GDP, it is far more densely populated<br />
in comparison to the other cities<br />
with similar land area. Firstly, when<br />
evaluated for its built stock, NYC<br />
showed that it still has a long way to<br />
go for greening its buildings (only 5%<br />
of the city built stock is green). NYC’s<br />
buildings also consume very large<br />
amounts of energy (80%) as well as<br />
emit a large volume of CO 2<br />
(74%),<br />
which explain the poor performance<br />
on the Green Building Efficiency and<br />
Performance dimension.<br />
However, NYC does manage to be in<br />
top 3 on Green City metrics. This is<br />
because the city performs exceptionally<br />
well on the renewable energy<br />
metric, and invests a lot of efforts on<br />
encouraging energy re-use. Moreover,<br />
although the city has one of the highest<br />
city-wide CO 2<br />
emissions figure (which<br />
can be attributed in part to its large<br />
population), this figure shows better<br />
results when normalized per capita and<br />
per GDP pushing NYC to top 5 on these<br />
metrics. It seems that NYC is indeed<br />
investing a lot of effort on greening<br />
the entire environment, but the city<br />
may require more focused attention to<br />
green buildings, as they still contribute<br />
the most to CO 2<br />
emissions and energy<br />
consumption. NYC has announced<br />
many sustainable city initiatives in<br />
recent years, which will take time to be<br />
implemented and to show performance<br />
gains in a report such as this; that said,<br />
it will be very interesting to see how<br />
NYC fairs in future rankings.<br />
In contrast to NYC, Sydney would have<br />
topped the list of Global Cities for<br />
green buildings if only it performed<br />
better on its built landscape. Sydney<br />
ranked first on green building culture<br />
and environment and managed to rank<br />
second on green building efficiency<br />
and performance, but does not have a<br />
strong number of green buildings on its<br />
skyline. Despite this, Sydney emits the<br />
least CO 2<br />
, recycles the most waste (as<br />
a percentage of total waste-to-landfill),<br />
and consumes more renewable energy<br />
than the vast majority of the other<br />
cities (with the exception of New York).<br />
Thus, Sydney was close to being in<br />
the top 3 if it did better on its green<br />
building landscape, but having only 6%<br />
of its total built stock “certified green”,<br />
totaling only 67 green buildings, Sydney<br />
slid in the rankings.<br />
Cities are making a lot of efforts in<br />
order to turn their built stock green,<br />
and many best practices are being put<br />
in place for other cities to learn from.<br />
For instance, Abu Dhabi has built the<br />
world’s most sustainable low-carbon<br />
city – Masdar City – which currently<br />
has one of the world’s largest efficient<br />
built-stocks, and is comprised of only<br />
certified buildings; Masdar is still in its<br />
infancy, but provides a glimpse into<br />
how future cities could be designed.<br />
Beijing has set interesting plans to<br />
construct ecological demonstration<br />
zones, within which all buildings must<br />
meet a specific certification standard.<br />
Dubai has launched the “Technical<br />
Guidelines for Retrofitting Existing<br />
Buildings” handbook in both English<br />
and Arabic, to educate owners,<br />
operators, and end-users on ways to<br />
reduce energy and water use, enhance<br />
the longevity of the building stock, and<br />
improve habitant’s well-being.<br />
Though energy efficiency and CO 2<br />
emissions are being measured by<br />
most Global Cities today, it was<br />
disparaging to find that water<br />
consumption figures were difficult to<br />
gather. Water is arguably the most<br />
precious resource on earth, and to not<br />
have city-wide consumption figures<br />
in 2014 is unacceptable. We look<br />
forward to future Green Building City<br />
Rankings which include water efficiency<br />
performance measures.<br />
Overall, the green building movement<br />
in the past <strong>10</strong> years has witnessed<br />
exceptional growth, and we have seen<br />
“new cities” such as Dubai, Singapore<br />
and Shanghai make significant gains.<br />
We have also seen older cities like NYC<br />
struggle with its old infrastructure and<br />
growing population. But Paris proves<br />
to us that old cities do not have to<br />
be trapped and weighed down by<br />
aging infrastructure; a strategic and<br />
methodical approach to retrofitting can<br />
dramatically improve efficiency.<br />
All in all, the intensifying efforts and<br />
action plans aimed at greening the<br />
built stock in a city is important, not<br />
only to reduce the impact on the<br />
environment during construction, but<br />
also for the buildings to operate in a<br />
green and more efficient matter. Green<br />
buildings are the pillars to building<br />
more sustainable cities around the<br />
world; and building more sustainable<br />
cities around the world is integral to<br />
achieving sustainable development<br />
and preserving our world’s resourcing<br />
for present and future generations.<br />
The Global Cities in our ranking shows<br />
us that the green building movement<br />
is alive and well, and that there are a<br />
myriad of approaches to building and<br />
greening a city’s built environment.<br />
There is no “right approach” and every<br />
city must adjust its strategy based on<br />
where in its sustainability journey each<br />
city finds itself. The key is to focus on<br />
driving gains in performance metrics,<br />
versus focusing and measuring green<br />
building activity alone. In the green<br />
building race, the end-result and bigpicture<br />
of living in sustainable, efficient<br />
and low-consumption cities is more<br />
important than how many buildings can<br />
be labeled as “green”.<br />
