We are pleased to share the Mitigation Action Facility’s Annual Report 2025 in a new digital format, providing an overview of key developments, achievements, and impact over the past year.
It highlights major portfolio milestones and project stories from around the world, showcasing progress towards sectoral decarbonisation through innovative financing, strong partnerships, and people-centred approaches. The report also covers the Mitigation Action Facility’s ongoing evolution as a credible climate finance platform, as well as its role as a Knowledge and Learning Hub.
“As the urgency of climate action continues to grow, so too does the demand for ambitious, scalable solutions. Throughout the year, we strengthened our portfolio of transformational mitigation projects across the energy, transport, and industry sectors, supporting partner countries in turning climate ambition into tangible action.”
– Philipp Munzinger, Head of the Technical Support Unit (TSU) to the Mitigation Action Facility

Project milestones in 2025
Mitigation Action Facility projects reached major milestones this past year. We highlighted a few of them:
The Knowledge & Learning Hub in 2025
In 2025, the Mitigation Action Facility further strengthened its role as Knowledge and Learning Hub, connecting projects, partners, and the wider climate finance community. It engaged with over 70 institutions across 14 international events and over 10 virtual project exchange formats.
Learning from implementation increasingly informed strategic decisions, improved processes and supported replication and transformational change across the portfolio. With 6 Evaluation & Learning Exercises, 12 mitigation support assignments, 16 financial mechanism services, and 20 GESI support services, continuous learning and adaptive management remained central to portfolio implementation at the Mitigation Action Facility.
In 2025, the Mitigation Action Facility also continued to expand its digital infrastructure and knowledge dissemination efforts to strengthen learning across the portfolio and beyond with 109 knowledge learning products produced and 334 knowledge sharing events organised.
Finally, guidance documents and learning-related policies were developed to guide activities of the Mitigation Action Facility portfolio.
What we learned in 2025
- Early support strengthens implementation readiness
- Climate finance solutions require innovation
