Deutsche Umwelthilfe files constitutional complaint against building modernization law.

Berlin – The environmental organization Deutsche Umwelthilfe (DUH), alongside four tenants, has lodged a constitutional complaint against the Building Modernization Act (GModG). DUH contends the law is unconstitutional, arguing it fails to adequately promote climate protection and jeopardizes the living conditions of future generations.

The complaint asserts that the law lacks a clear pathway towards climate neutrality. Instead, it permits the continued use of fossil fuel oil and gas heating systems for decades. DUH states this will lead to significant additional emissions, exceeding Germany's carbon budget before 2033, more than a decade ahead of the 2045 climate neutrality target.

The organization also criticizes the law for shifting the cost risks associated with fossil fuels, particularly onto tenants who have no say in heating system choices. According to DUH, the act fosters dependence on fossil fuels, compromising the freedom and security of future generations.

"The Federal Constitutional Court must set limits for this law," said DUH's Federal Managing Director Barbara Metz. Remo Klinger, providing legal representation, noted that the law creates confusion rather than providing clear direction towards climate neutrality. DUH is calling for legislative changes that ensure a defined phase-out of fossil fuels and mitigate the impacts of climate change.
