About us

Climate Policy Radar is an independent non-profit building open, credible data infrastructure and AI-powered tools for climate, nature, and development action.

Our data and tools help governments, researchers, international organisations, civil society, and the private sector to understand and advance effective climate policies and deploy climate finance. Harnessing data science and AI – including pioneering applications of natural language processing in this field – we make previously unstructured, siloed data easier to find, understand, and act on.

We are a team of policy experts, engineers, data scientists, product thinkers, communicators, and operators. We care deeply about how we work – our values, culture, and ways of collaborating – as well as what we build. As part of that, we have embraced a flexible, hybrid approach to work, including a four-day workweek.
