Nature Conservation Association Criticizes Planned Heating Law Reform - Germany's heating law reform sparks backlash from climate advocates
Germany's plans to reform heating laws have drawn sharp criticism from environmental groups. The Nature and Biodiversity Conservation Union (Nabu) condemned the government's decision to drop a key climate requirement for homeowners. Under the new rules, replacing old heating systems will no longer demand 65% renewable energy use.
The federal government's proposed changes relax obligations for homeowners upgrading their heating. Instead of enforcing a 65% renewable energy share, the reform introduces a 'green gas quota'. This would gradually increase the use of biomethane and synthetic fuels in oil and gas systems.
Nabu argued that scrapping the renewable energy target undermines climate efforts in the building sector. The organisation has long highlighted the sector's failure to meet climate goals. Steffi Ober, a Nabu spokesperson, dismissed the green gas plan as inefficient and unlikely to cut fossil emissions.
Heat pumps remain the most widely adopted alternative, with sales jumping 55% in 2025. They now account for nearly half of all new heating installations. Nabu insists they offer the most cost-effective and climate-friendly option for consumers.
Over 10 million German homes are currently poorly modernised. The reform's long-term impact on these properties remains unclear, as no specific data has been released.
The revised heating law removes a major renewable energy requirement for homeowners. Critics warn this could slow progress in reducing building emissions. With heat pumps already gaining ground, the debate over the best path to decarbonise heating continues.
