Chevron Corporate Responsibility Report 2009

Climate Change
The first two stages of the Escravos Gas
Project (EGP) in Nigeria — EGP-1 and
EGP-2 — were completed in 1997 and 2000,
respectively. EGP-2 raised the company’s
gas processing inlet capacity from 165
mmcf/d to 285 mmcf/d. EGP-3, a follow-up
to EGP-1 and EGP-2, is expected to begin
operation in 2010. EGP-3 will process up to
an additional 395 mmcf/d, part of which
will be used as feedstock for the Escravos
Gas-to-Liquids Project.
The Escravos Gas-to-Liquids Project will
upgrade approximately 325 mmcf/d of
gas into almost 33,200 barrels per day of
high-quality diesel, naphtha, and liquefied
petroleum gas. Construction began in 2006,
and first production is forecasted for 2012.
The West African Gas Pipeline, a 421-mile
(678-km) high-pressure natural gas
pipeline, constructed and operated by the
West African Gas Pipeline Co., of which
Chevron is the largest shareholder, has an
initial capacity to transport 170 mmcf/d of
natural gas from Nigeria’s Niger Delta to
Ghana, Togo and Benin. The West African
Gas Pipeline transports gas that would
have been flared to now fill energy supply
gaps in western Africa. This will help
us reduce emissions because it allows
access to markets and provides the ability
to deliver gas to end users. The pipeline
began transporting gas in 2008 and will be
complete in 2010.
Manufacturing Our eight Chevronoperated
refineries created a formal
network in 2009 to share best practices in
flare reduction. The refineries are working
to reduce flaring through flare gas
recovery, source control, and maintenance
practices and procedures, and they have
shared their successes for several years.
Chevron’s Pembroke, United Kingdom,
refinery started using a sulfur oxide
reduction catalyst in the cracking process
after U.S.-based refineries found that the
catalyst successfully reduced sulfur oxide.
Other flare reduction techniques were
found to improve energy efficiency and
produce cost savings.
Reducing Emissions —
Carbon Dioxide Injection
Chevron has several major natural gas
investments off the western coast of
Australia, including the Gorgon Project,
which will include the world’s largest
commercial-scale GHG storage site. The
Gorgon Project will position Australia as a
leader in the application of GHG storage,
with up to approximately 3.4 million metric
tons a year of CO 2 being injected and
stored underground. Over the life of the
project, it is anticipated that approximately
120 million metric tons of GHG emissions
will have been avoided because of the
Gorgon CO 2 -injection project.
The proposed injection location will be
on the northeast coast of Barrow Island
near the gas processing plant. This site
was selected to maximize the migration
distance from major geologic faults and to
limit environmental impacts. The injection
wells will be directionally drilled from
discrete surface locations to minimize the
area of land required for the well sites,
surface facilities, pipelines and access
roads. Extensive monitoring, including
well- pressure measurement and seismic
surveys, will provide information required
to update the reservoir models and predict
the behavior of the injected CO 2 . The
Gorgon Project is the first project to be
regulated under legislation dedicated to
GHG storage and is the world’s first largescale
storage project to have been subjected
to an exhaustive, publicly available
environmental impact assessment. Project
construction has begun, and injection
operations are anticipated to begin in 2014.
Chevron and its partners are committed to
sharing data from the project to aid in the
Office Facility Fitness
Six Principles of Sustainability
More than 100 Chevron office facilities are managed by the Chevron Business
and Real Estate Services team, which is guided by its Six Principles of Sustainability.

Our Sustainability
Program
We improve our facilities’
efficiency with the
implementation of
technology and operating
procedures. Using the
ENERGY STAR ® program
of the U.S. Environmental
Protection Agency, our
goal is to achieve topquartile
energy efficiency
within five years.
In addition to tracking
our water use, we install
water-saving fittings
and fixtures. We also
have a project to use
local recycled water
for cooling towers and
for a large landscapeirrigation
system at our
headquarters in San
Ramon, California.
Our projects increasingly
incorporate materials
made from recycled
or renewable content.
We reuse our modular
work spaces and furnishings.
We implemented
recycling programs
at various office sites
worldwide to divert our
landfill-bound waste.
Through guidance provided
by the U.S. Green
Building Council’s LEED
program, we are identifying
ways to improve
our operations. Making
use of natural light is
one practice used at
many of our sites.
We partner with
Chevron employees
to promote conservation.
Ride-sharing and
Lug-a-Mug programs
(to use nondisposable
cups) are examples of
how employees contribute
to our success.
We continue to
identify efficiencies,
learn from best practices
and implement
improvements.
