Decarbonizing the Heating Sector - Challenges and Solutions — •Florian Weiser — MVV Energie AG, Mannheim, Germany

The German climate targets cannot be reached without decarbonizing the heating sector that currently accounts for approximately one third of Germany's yearly CO2 emissions. Green heating technologies are already technically available for decentralized applications as well as for district heating systems, e.g. electrical heat pumps and biomass-fired systems. However, despite technical progress, green heating technologies will continue to be significantly more expensive than fossil-fired heating systems. Closing the CO2 gap between a "businesses as usual" path with current policies and a path consistent with the climate targets in the building heating sector will cost approximately 9 billion euros in the year 2030. The MVV study "Take-Off Wärmewende" proposes a mixture of instruments in order to accelerate the decarbonization of the building heating sector consisting of a CO2 tax on fossil fuels, CO2 limits for the building stock, municipal heat plans as well as funding schemes for green heat and energy efficiency. Furthermore, decarbonization policies for the building heating sector in Switzerland, Denmark, UK and France are analyzed.
