Germany faces challenges in heat transition and CO2 reduction

Germany faces significant challenges in its transition to climate neutrality, particularly within the building and heating sectors. According to the 2024 dena Building Report, fossil fuels still account for nearly 80 percent of heat generation in the country's building stock, contributing to approximately 40 percent of Germany's total CO2 emissions.

In the Hamburg region, the continued operation of the Wedel coal-fired power plant highlights infrastructure delays. Although intended to be decommissioned earlier, the plant is now expected to remain online until July 1, 2027, due to delays in completing replacement facilities and the Dradenau plant. Since 2020, the Wedel plant has emitted approximately 6.8 million tons of CO2, an amount comparable to the total emissions of the city of Hamburg over nearly nine months.

The report suggests that political debates and legislative design flaws regarding the Building Energy Act have slowed the momentum for heat pumps and renewable alternatives, potentially delaying the necessary emissions reduction for several years.
