The city of Ostfildern
takes a long-term approach
to climate protection
“For the first time we, as a local
government, can evaluate our
previous climate protection efforts
on a large scale and coordinate
our future actions. As author of
the overall assessment and the
main initiator of the upcoming
measures Drees & Sommer has
dramatically advanced our local
climate protection.”
Frank Hettler,
Department of Energy Management Ostfildern
Integrated climate protection concepts are an effective means
for cities and districts that want to systematically reduce greenhouse
gas emissions. Drees & Sommer has supported the city of Ostfildern
in establishing such a concept, identifying the most effective local
measures. The experts are also helping with implementation.

Kick-off
Stakeholder workshop
Collection and validation of basic data
The European Union’s climate protection
goal is to reduce greenhouse gas
emissions to below 20 percent of 1990
levels by 2020. Local government
authorities can now take measures to
meet such regulatory requirements. One
thing is certain: This ambitious target
does not seem achievable without the
cities and their citizens.
The district of Esslingen is playing an
exemplary role in this respect. The
municipality with a total of six districts
and some 40,000 inhabitants has
been focused on the subject of energy
efficiency for years. In 2012, the city
decided to strategically pool its efforts
and to continuously reduce climatedamaging
carbon dioxide (CO2) emissions
over the next few years.
The target is a reduction of 16 percent
An integrated climate protection concept
forms the basis for further action. It
covers nearly every aspect of daily life,
from housing to mobility. A team of
engineering and infrastructure experts
from Drees & Sommer was charged with
its preparation and the necessary preliminary
investigations. The specialists
had already undertaken a related pilot
project for the borough of Nellingen the
previous year.
The main objectives of the Ostfildern
climate protection concept are the
reduction of carbon emissions by
16 percent or 32,000 tonnes and a
significant increase in the share of
renewable energy in households and
industry. Drees & Sommer was able to
underpin these objectives with concrete
figures: It was established, for example,
that Ostfildern’s households are
responsible for roughly 42 percent of
the carbon emissions and therefore
have a correspondingly very high savings
potential.
