Welcome to the Climate Policy Atlas: a project presenting high-resolution, curated and open data on energy and climate policies and targets. The Climate Policy Atlas is based on the Climate and Energy Policy Ontology, a structured, semantic framework for organising climate and energy policy instrument data in a consistent and comparable way. The project aims to enable empirical policy analysis and make existing policy data more accessible and interoperable. The Climate Policy Atlas is funded by the German Research Foundation DFG project NFDI4Energy.
