About us

Climate Policy Radar is on a mission to organise, analyse, and democratise the world’s climate law and policy data. We build open databases and research tools so people can discover, understand and generate data-driven insights on public laws and policies. Our work helps governments, researchers, international organisations, civil society, and the private sector to understand and advance effective climate policies and deploy climate finance. Nearly 350,000 users from over 100 countries already use Climate Policy Radar’s platform, which enables searching through half a million pages documenting climate action, by government, worldwide.

Harnessing data science and AI, and pioneering the application of natural language processing to this domain, our work unlocks previously inaccessible, unstructured data. This serves to enhance accountability, and promote data democratisation, transforming our search engine into a virtual research assistant for the climate world, powered by a unique open knowledge graph. We are deeply embedded in the global climate and AI communities, and count some of the most important organisations and global climate leaders amongst our users, advocates, friends and advisors.

We’re a Community Interest Company, championing an open science approach that aims to promote collaboration, transparency and justice — including open code and data. We are currently around 20 people, and are embarking on a significant growth phase. Our team is characterised by its high level of expertise, shared mission-driven ethos, and a strong collaborative spirit that welcomes individuals from diverse backgrounds, perspectives, and experiences.

  • Continuing to develop our tools for  supporting data partners in curating large libraries of climate-related documents

  • Building out our “virtual research assistant” roadmap ambition, including leveraging and productionising large language models to help researchers analyse data
