Facing the climate challenge -
Hamburg’s approach to
sustainable development
and smart growth
Peter Lindlahr
The City of Hamburg
Head of the Coordination Center for Climate Issues
2

Who we are,
and where we come from –
a brief introduction…
Germany’s second largest city and one of 16 federal states
with a population of 1.7 M in the city and more than 4 M in the metropolitan area
Second largest port & aviation technology center in Europe
Green city on the waterside (40 % green and water spaces)
Rich variety in the metropolitan region (14 counties)
Annual CO2-emissions will decrease by 2 M tons within 5 years as compared to now
(almost -30% p.c. since 1990) as laid out in the recently launched Climate Action
Plan, which provides an extra funding of 25 M Euro for the year 2008 3

Our criteria of success
for “Good Governance”
Hamburg stands for well-balanced centralized / decentralized decision-making
The Hamburg concept considers ecological efforts as a transversal task, and
turns it into job generation in engineering and manufacturing businesses
Energy savings need feasable incentives (e.g., the 50/50-program: schools
reducing their energy consumption keep 50% of the monetary savings)
The Hamburg approach is a two-folded strategy of subsidies and regulation.
It provides a substantial project funding to stimulate the market, while at the
same time the Hamburg state government establishes specific codes (e.g.,
green building standards) 4

Significant challenges
for a comprehensive
metropolitan strategy
are…
█ clean energy
█ adaptation and mitigation efforts to
combat climate change

Mobility
The major tasks are to …
develop public transport through an integrated concept
for the bus- and metro-system:
common schedule - common tariff- common ticketing
extend the regional approach for the overall traffic management plan
speed up the implementation of advanced engine technologies
establish green ICT in traffic management systems

Best Practice in smart transportation:
Zero Emission Public Transport -
The Hamburg fuel cell concept
Fuel-cell powered hydrogen buses are 100% environmentally compatible
and operate at low noise emission rates
HOCHBAHN operates nine fuel cell powered buses in the regular daily
inner-city traffic thus constituting the largest hydrogen powered bus fleet in
the world
11

Advanced Urban Planning
The major tasks are to …
establish criteria for sustainable planning in development plans and building
permits
create urbanity and urban structure with a inspiring mix of public spaces,
new districts with residential and office usage, places of consumption,
institutions and networks, cultural and entertainment facilities
and a dense grid of walkways and cyclepaths
extend spatial conversion (brown fields – harbour, railway, industrial, etc.)

16

Clean Energy Issues
The major tasks are to …
implement Carbon Capture Storage
increase the percentage of renewables in the regional energy mix
support zero-emission technologies like fuel cell or hybrid
establish mandatory standards on energy efficiency in buildings
start or extend Eco Partnerships (“economy meets ecology”)
17

Adaptation and mitigation efforts Main embankment line !
to combat climate change
The major tasks are to …
launch programs with well defined projects and measures,
such as the Hamburg Climate Action Plan (170 projects within 5 years)
start capacity building in R&D and applied sciences
establish city networks on adaptation issues (e.g., urban flood
management) and focus on climate change on a regional scale
