Germany loses momentum on climate action – heat pumps and electric cars catching up only slowly

Germany’s greenhouse gas emissions fell only slightly in 2025, declining by 9 million tonnes, or 1.5 percent compared with the previous year – less than half the reduction achieved in 2024. For the first time, the sluggish uptake of climate technologies in the buildings and transport sectors is visibly reflected in the overall emission balance. That said, sales of heat pumps and electric vehicles are increasing.

This new study by our sister organisation, Agora Energiewende, summarises key developments in energy transition and climate protection over the past year, and provides the first qualified estimate of greenhouse gas emissions in 2025. Authors from the Agora Verkehrswende team contributed to the section on the transport sector.
