Germany’s greenhouse gas emissions continued their downward trend in the past year, though at a slower pace than previously recorded. While many sectors saw a reduction in CO2 output, emissions rose in both the transportation and building sectors, according to data released by the independent organization Agora Energiewende.
Economic Slowdown Contributes to Lower CO2 Emissions
A significant factor in the overall decrease is the weakened state of the German economy and challenging global market conditions. Factors like US trade policies, global overcapacity in industries like steel and chemicals, and declining domestic demand are impacting energy-intensive industries, leading to reduced production and, consequently, lower CO2 emissions. “This is not good news, however, because it does not represent sustainable, structural emissions reductions,” explained Julia Bläsius, Director of Agora Energiewende.
The expansion of solar energy also contributed to the decline. In 2025, photovoltaic systems generated more electricity than coal and gas-fired power plants for the first time, becoming the second most important source of electricity in Germany after wind power. This shift resulted in a three-million-ton reduction in CO2 emissions from the energy sector.
Germany Remains on Track to Meet Climate Goals Overall
Based on the available data, Germany is currently on track to meet its national climate targets. However, the rate of emissions reduction slowed considerably last year, with only half as much greenhouse gas being saved compared to 2024. The increase in emissions from transportation and buildings – driven by higher fuel consumption and increased heating oil and gas use due to cold weather – is a key factor.
“Too little is being done to switch to climate-friendly technologies such as the electric car and the heat pump in both areas,” Bläsius stated. Failure to accelerate emissions reductions could jeopardize Germany’s ability to meet its 2030 climate goals.
Transition in Transportation and Buildings Progressing Slowly
The transition to sustainable transportation and the replacement of oil and gas heating systems with climate-friendly alternatives are progressing slowly. While around 300,000 heat pumps were sold last year – exceeding the number of gas heaters – high investment costs and uncertainty surrounding the “Heating Law” (officially the Building Energy Act) are hindering faster adoption. Many homeowners are unsure which heating system to choose, according to Bläsius.
The German government is currently working on a revised regulation, with the unions-led Ministry of Economic Affairs and the SPD-led Ministry of Construction playing key roles. The CDU and CSU are pushing to repeal the previous “Heating Law” without a replacement, with the new law to be called the Building Modernization Act. Discussions are ongoing regarding the future state funding for heating system replacements, with some voices within the unions advocating for reduced support for heat pumps.
Experts Call for New Legislation
Julia Bläsius of Agora Energiewende advocates for continued financial support, particularly for low-income homeowners. She emphasizes that the government must provide regulatory certainty in 2026 by addressing key legislation such as the Renewable Energy Act and the Building Energy Act. Furthermore, she stresses the urgent need for investment in modernizing the economy and transitioning to climate-neutral production.
Frequently Asked Questions
What is Agora Energiewende?
Agora Energiewende is an organization that, according to its own statements, is politically independent and provides data-driven analysis on the energy transition in Germany, based on data from various sources including authorities and industry.
What sectors saw an increase in emissions?
Emissions increased in the transportation and building sectors. In transportation, higher fuel consumption was observed, while in buildings, increased oil and gas consumption for heating contributed to the rise.
What is the Building Modernization Act?
The Building Modernization Act is a new law being developed by the German government to replace the previous “Heating Law” (Building Energy Act). It will address how heating system replacements will be financially supported by the state in the future.
As Germany navigates its energy transition, what role will government policy and individual consumer choices play in accelerating emissions reductions and achieving long-term climate goals?
