Germany’s Climate Progress in 2025 Shows Mixed Results Amid Record Emissions Trading Revenues

In 2025, Germany continued its efforts to reduce greenhouse gas emissions, achieving a modest decrease of 1.5% to approximately 640 million tons CO2 equivalent. However, this reduction marks a slowdown compared to 2024, with emissions savings less than half of the previous year's progress, signaling challenges in sustaining climate protection momentum.

The energy sector, relying heavily on wind and solar energy which accounted for 55.3% of electricity consumption, managed to reduce emissions by 1.5% despite encountering a weak wind year. The solar capacity saw significant growth, supported by favourable weather, though the expansion of wind energy, especially offshore, fell short of expectations, prompting calls for policy reforms.

In contrast, emissions in the building sector rose by 3%, attributed to cooler temperatures increasing heating demand, while the transport sector saw a slight rise of 1.4% due to increased fuel sales and slow electrification rates. Heat pumps are increasingly becoming standard in new buildings, reflecting structural changes in heating, yet challenges remain with rising costs and slower adoption of electric vehicles in transport.

Financially, Germany benefited from record revenues in emissions trading schemes, raising more than €21.4 billion in 2025 through European and national systems, up from €18.5 billion in 2024. These funds flow into the Climate and Transformation Fund, bolstering financing for the energy transition and climate protection initiatives. The pricing mechanism on greenhouse gases is designed to incentivize reduced fossil fuel use across the economy and consumers.

Electricity prices experienced a 13% increase due to higher natural gas costs, though household electricity prices saw slight decreases, highlighting complex market dynamics. Investment in climate-neutral technologies has risen nearly 10% in recent years, positioning Germany with a 13% share in global markets for relevant sectors despite geopolitical uncertainties.

Experts emphasise the critical need for all sectors to actively advance toward climate goals by ensuring attractive electricity pricing, stable CO2 pricing pathways, and targeted funding programs. The varied sectoral emissions trends and financial successes underline both challenges and opportunities on Germany’s path to a sustainable energy future.
