Carbon intensity is estimated by our laboratory using publicly available area supply-demand data and the carbon intensity factors published by the UK NESO. 

Data sources: Area actual supply data from regional transmission and distribution operators: Hokuriku Electric Power Network, TEPCO Power Grid, Kansai Transmission and Distribution, and Kyushu Electric Power Transmission and Distribution; and the UK NESO report: https://www.neso.energy/document/373936/download

Note: The carbon intensity values shown on this page are our laboratory’s own estimates and are not values calculated or published by the transmission and distribution companies. The denominator is local generation, calculated by subtracting net imports from area demand
