Policy reversals and the undermining of trusted data and analysis tested the foundations of climate progress in 2025. But even in turbulent times, our work with decision-makers around the world continued to drive effective and equitable climate action.
Together with our global network of Climate Ambassadors, we informed policies, worked with leaders in middle income countries to rapidly reduce emissions, helped organizations navigate climate risk, accelerated the transition away from fossil fuels, and enhanced our tools that give leaders the clarity to act.
