Germany's climate heating plans weakened by political compromise on fossil fuels

Germany’s plans for climate-friendly heating have faced a major setback after political negotiations weakened key rules. The conservative Union bloc pressured the Social Democrats (SPD) into allowing new gas and oil boilers—despite the country’s 2045 climate neutrality target. Landlords now have more freedom to choose cheaper, fossil-fuel systems over greener alternatives like heat pumps. The dispute centred on cost and responsibility. Gas and oil boilers remain far cheaper upfront, even with state subsidies for heat pumps failing to close the price gap. The SPD initially wanted stricter limits but conceded to the Union’s demands, letting landlords keep installing fossil-fuel systems.

Landlords are expected to favour the cheapest option, even if climate-friendly systems save money in the long run. Under the new rules, they can pass future biofuel mandates and rising CO₂ prices onto tenants. The SPD secured a compromise: landlords must now cover half of certain operating expenses if they choose fossil heating. Yet without rent controls or cost-sharing limits, critics argue tenants could still bear the financial burden. The SPD claims the deal balances heating policy rollbacks with tenant protections. But neither party plans to introduce rent caps or other measures to stop landlords from shifting costs. While modernisation expenses can already be passed to renters, the actual cost difference between a heat pump and a gas boiler may not always fall on tenants.

The agreement keeps gas and oil boilers as an option, delaying Germany’s shift to greener heating. Landlords gain flexibility, but tenants risk higher costs from future climate policies. Without stricter safeguards, the financial impact of fossil-fuel systems could still land on renters.
