Climate & Environment
Climate change is the defining challenge of our time.
UNDP supports over 140 countries in their climate action efforts, helping them develop and implement ambitious Nationally Determined Contributions, transition to clean energy, build climate resilience, and protect biodiversity. We mobilize climate finance, strengthen policy frameworks, and scale up nature-based solutions to address the interlinked crises of climate change and biodiversity loss.
