Berlin – A compromise on Germany’s building energy law, known colloquially as the “heating law,” has been reached, potentially reshaping how homeowners heat their homes and impacting the country’s climate goals. The agreement, forged between the governing Social Democrats (SPD) and the opposition Christian Democratic Union (CDU), represents a significant shift from previous iterations of the law and has sparked debate over its effectiveness in reducing carbon emissions. The revised legislation, expected to come into effect on July 1, 2026, aims to regulate the gradual replacement of oil and gas heating systems with climate-friendly alternatives.
The core of the debate centered around a rule proposed by former Economics Minister Robert Habeck of the Green Party, requiring all newly installed heating systems to operate with at least 65% renewable energy. This provision, initially intended for new buildings in designated development areas, faced strong opposition from the CDU, who argued it was overly restrictive and financially burdensome for homeowners. The CDU prevailed in scrapping the 65% rule, with Union faction leader Friedrich Spahn stating, “All heating types are again possible.” The new agreement stipulates that existing, functional heating systems will not be subject to mandatory replacement.
Still, the agreement doesn’t entirely abandon the push for cleaner heating. New gas and oil heating systems will be required to operate with an increasing proportion of climate-friendly fuels, such as biomethane. A “green gas quota” will be introduced, starting at 10% by 2029 and rising in stages to reach a higher percentage by 2040. Crucially, the carbon dioxide (CO2) price will be waived for this climate-friendly fuel component, potentially incentivizing its use. Industry representatives have cautioned that the availability and cost of these alternative fuels remain significant challenges, potentially leading to higher expenses for homeowners.
Financial Support and Tenant Protections
Despite the shift away from mandatory replacement, financial support for climate-friendly heating solutions will continue. The government intends to maintain funding for the purchase of technologies like heat pumps until at least 2029. This support aims to encourage homeowners to voluntarily transition to more sustainable heating options. Protecting tenants from potentially high costs associated with new heating systems is likewise a priority. The agreement includes provisions to shield renters from “excessive additional costs” resulting from the installation of uneconomical heating systems, though specific details remain unclear.
Impact on Climate Goals
The coalition government maintains that Germany’s overall climate protection goals remain unchanged. A formal evaluation is planned for 2030 to assess whether the building sector is on track to meet its climate targets. If the evaluation reveals shortcomings, further adjustments to the law may be considered. However, experts note that both the transportation and building sectors have historically lagged behind in achieving their climate objectives.
Timeline and Next Steps
On Tuesday, representatives from the CDU and SPD presented a five-page outline of the agreement. A draft bill is expected to be presented by the cabinet by Easter, with a parliamentary vote to follow. The new law is slated to take effect on July 1, 2026. The coalition’s agreement marks a significant turning point in Germany’s energy transition, balancing environmental concerns with the practical realities faced by homeowners.
The revised law represents a compromise that attempts to address concerns about affordability and feasibility although still moving towards a more sustainable heating future. The effectiveness of this approach will depend on the availability and cost of alternative fuels, the continued availability of financial support, and the outcome of the 2030 evaluation. Further details on the implementation of tenant protections will also be crucial in ensuring a fair transition for all.
The debate surrounding the “heating law” underscores the complexities of implementing ambitious climate policies in a way that is both effective, and equitable. As Germany moves forward with its energy transition, ongoing dialogue and adaptation will be essential to achieving its climate goals.
