Mayors Voices: Lord Mayor of Heidelberg Eckart Würzner

Formerly a freight yard, the Bahnstadt area will now house a sustainable city district where all the buildings are being built to meet strict energy efficiency standards. The city of Heidelberg, Germany is building one of the world’s largest developments of passive housing – buildings that are highly energy efficient. The district, known as the Bahnstadt, is being built around three core concepts: reduce energy need, generage energy cleanly and efficiently and use that energy as efficiently as possible.

These development’s ultra-low energy buildings will require little energy for heating or cooling.  All buildings in Bahnstadt will be built according to passive house standards and will use energy from biomass, geothermal and other renewable energy sources.

Heidelberg’s Mayor Würzner is leading the way in climate protection and sustainable city development, and had this to say about the C40 Cities mission and Summit:

"Cities play a central part in the fight against global warming and climate change. Cities cover only two per cent of the earth's land surface whereas their energy consumption makes up 25 per cent of the global energy consumption and 80 per cent of the greenhouse gas emissions. A question of vital importance is how prospering cities can reach their ambitious climate protection goals. The City of Heidelberg is focused on climate protection. It sets an example following the motto of “Think globally – act locally”. One of our major achievements is that we have been able to reduce the energy consumption in real estate owned by the City by approximately 50 per cent. The good results in saving energy in municipal buildings show that the path we have chosen is right and that we are able to reach the goal adopted by the City Council: a 20 per cent reduction in municipal CO2 emissions, compared to 1987, by 2015. The C40 Summit offers cities an excellent platform to jointly develop strategies for climate protection."
