To accelerate the expansion of renewable energies on a global scale, KfW specifically finances future technologies. These include, for example, green hydrogen, photovoltaics, solar thermal energy, and onshore and offshore wind projects. In doing so, KfW always keeps in mind the interests of developing and emerging countries and their participation in tapping the potential of renewable energies.

To meet the globally growing energy demand with climate-friendly sources, the possibilities for producing and using renewable energies must be fully exploited. Natural energy sources such as sunlight, wind, water, waves, biomass, and geothermal energy offer enormous potential where available, especially in developing and emerging countries.

In 2025, KfW’s climate and environmental commitments – through its banking subsidiaries KfW IPEX-Bank and DEG and its Development Bank division – amounted to around EUR 14 billion (2024: EUR 12.6 billion). This represents just under 40 per cent of its commitments.

Between 2021 and 2025, total commitments for climate and environmental protection financing amounted to around EUR 56 billion. (As of April 2026)

Energy that is saved — i.e., not consumed in the first place — is the most climate-friendly form of energy. Savings and efficiency therefore reduce costs and greenhouse gas emissions. In mobility, buildings, industry, and public services, the potential for savings is significant in partner countries.

Therefore, alongside investments in more efficient power systems in several partner countries, KfW supports a wide range of efficiency initiatives. KfW provides, for example, funding to enable municipalities, companies, and public utilities to invest in environmental measures. These projects increase energy efficiency, improve living comfort, and substantially extend the life cycle of buildings.

The global investment need for expanding the hydrogen economy is very high and is estimated to exceed EUR 2 trillion by 2050.

KfW offers targeted and interlinked financing products to promote projects along the entire value chain of green hydrogen: from production through transport and storage to utilisation, including the necessary renewable energies.

Germany’s dependency on hydrogen imports (over 70% of total demand) creates an additional mandate to support German investments as well as the establishment of viable hydrogen partnerships.

• in 2025, financed renewable energy projects abroad with a cumulative capacity of 11.5 GW — a capacity that would cover Belgium’s annual electricity consumption;
• specifically finances future technologies such as floating offshore and solar thermal projects. This increases the chances of accelerating the energy transition and advancing the decarbonisation of energy generation more rapidly;
• participates in financing the world’s largest project for producing green ammonia in Saudi Arabia on an industrial scale (annual production of 1.2 million tonnes from the end of 2026), including its own wind and solar parks and electrolyzers from thyssenkrupp nucera;
• finances green electricity for over 37 million people via its banking subsidiary DEG,, saving more than 14 million tonnes of CO₂ annually. Additionally, the companies indirectly financed via funds produce 8.9 terawatt-hours of renewable energy, primarily biomass, reducing emissions by another 6 million tonnes of CO₂ per year;
• supports partner countries through KfW Development Bank in achieving their self-set climate goals. This will provide more than 1.3 million people access to modern energy supply, save over 1 million megawatt-hours of energy annually, and add more than 1,000 MW of renewable energy generation capacity in the coming years.
