The Carbon Intensity API is the official carbon intensity forecasting service for Great Britain, developed by the National Energy System Operator (NESO) in partnership with EDF, the University of Oxford, and WWF. It provides real-time, forecast, and historical carbon intensity data alongside generation mix information for GB electricity, with 96+ hour forecasts and 30-minute temporal resolution across 14 regional DNO boundaries. The API is publicly accessible with no authentication required and is licensed under CC BY 4.0.
