The Green Party’s building policy spokesperson, Taher Saleh, has expressed concerns that the government cannot specify the law’s potential effects, which raises questions about its constitutionality under existing climate protection mandates. The law aims to replace the reformed Building Energy Act and would allow the continued installation of certain new oil and gas heating systems. The Bundestag is scheduled to discuss the legislation for the first time next Thursday, amid ongoing uncertainty regarding future pricing of natural gas, biomethane, and green hydrogen.
