About climate change

Climate change threatens people’s lives and livelihoods, the survival of species, and the integrity of ecosystems all over the world. But Nature-based Solutions that protect and restore ecosystems absorb carbon dioxide and help shield communities from the effects of climate change. Investing in the conservation, restoration and sustainable management of nature can provide around a third  of climate mitigation needed by 2030.

Our work

The climate and biodiversity emergencies are not distinct, but two aspects of one crisis. Unsustainable human activity continues to compound the situation, and threatens not only our own survival but the foundation of life on Earth. Our response to these emergencies must be mutually reinforcing.

- Marseille Manifesto

Our ambition is for a world that limits temperature rise to 1.5°C through ambitious measures to mitigate climate change, and enables effective adaptation. We work to achieve this by monitoring the impacts of climate change and responses to it, helping governments implement effective Nature-based Solutions at scale, and ensuring that responses to climate change and its impacts are informed by evidence. We guide climate policy and action that is equitable and inclusive to bring the greatest benefits to societies, nature and economies.
