The necessary transition to a climate-neutral heat supply requires clear political signals, reliable framework conditions and a socially balanced design. The new German government is facing a wide range of tasks and there are numerous unanswered questions, not only with regard to the announced reform of the Building Energy Act – for example, regarding the ambitions for climate protection, the future role of renewable heating technologies and the requirements for existing buildings.
We discussed these and other topics with our guests at the Forum Wärmewende on July 9, 2025. For the podium we were able to invite Thomas Bareiß (CDU/CSU), Dr. Alaa Alhamwi (Bündnis 90/Die Grünen), Florian Zerzawy (FÖS) and Dr. Cezara Missing (Viessmann Climate Solutions).
Our conclusion: the heating transition is technically feasible and makes economic sense in the long term. But the transformation must be supported politically in order to be successful. The Federal Government must now quickly clarify how to proceed with the GEG.
