The Federal Climate Protection Act (KSG) sets binding greenhouse gas reduction targets. It states that Germany must reduce greenhouse gas emissions by at least 65 % by 2030 and 88 % by 2040 (compared to 1990). Achieve net greenhouse gas neutrality by 2045. After 2050, only negative greenhouse gas emissions are to be emitted.

Cities consume up to 75 percent of the energy generated worldwide. At the same time, they generate around 80 per cent of the global gross domestic product. They are thus responsible for up to 80 percent of mankind's energy-related CO₂ emissions. The future of cities will be crucial for environmentally sound development and combating climate change.

People's mobility and their access to affordable housing are also crucial for quality of life and thus major challenges for urban development policy. However, the inclusive city must also offer people the best access to education and health care.
The 2030 Agenda, which the global community agreed on in New York in 2015, contains important answers to these challenges. With the global sustainability goal 11, the states commit for the first time to sustainable, inclusive urban development worldwide!
