Two new assessments from the German Parliament (Bundestag) are fueling criticism of the country’s new heating law, raising questions about its compliance with both the German constitution and European Union law. The assessments provide further support to arguments against the regulations, which aim to transition heating systems away from fossil fuels. Minister Katherina Reiche acknowledges the seriousness of these legal challenges. Critics argue the law may be unconstitutional, potentially hindering its implementation. The expert opinions bolster their position, creating uncertainty around the future of the legislation. The assessments are expected to intensify the debate surrounding the heating law and its potential impact on homeowners and the energy sector.
