Germany's Building Modernization Act faces climate and legal scrutiny ahead of Bundestag vote

The German government is pushing ahead with the Building Modernization Act, a replacement for the reformed Building Energy Act. However, critics argue that key details about its climate impact and financial consequences remain unclear.

The draft bill is set for its first reading in the Bundestag next week, but questions linger over its effectiveness and legality.

The government has admitted it cannot yet assess how the proposed law will affect climate protection. Officials stated that a full evaluation of its environmental impact will only happen once the legislative process is complete. This delay has raised concerns among opposition lawmakers.

Kassem Taher Saleh, the Green Party’s housing policy spokesperson, criticised the government for lacking essential data. He claimed ministers have no forecasts on future price trends for natural gas, biomethane, or green hydrogen—key factors in the law’s success. Taher Saleh also argued that the government appears unaware of how the legislation will influence CO₂ emissions in the building sector. Beyond practical concerns, legal doubts have surfaced. Taher Saleh pointed out that the Basic Law prohibits any regression in climate protection. He described the current draft as unconstitutional, warning that it fails to meet existing legal standards for environmental safeguards.

The Building Modernization Act will proceed to its first Bundestag reading without clear answers on costs or emissions. The government’s inability to provide forecasts on energy prices and climate effects leaves the law’s future uncertain. Legal challenges may follow if the legislation is deemed inconsistent with constitutional climate protections.
