3 Figures provided by the Department for Business, Energy and Industrial Strategy (BEIS).
Carbon dioxide emissions (g/kWh): The weighted average of the carbon dioxide emitted in the production of electricity from each fuel source. This is calculated on the basis of figures provided by BEIS (details of these can be found on the Government website).
Radioactive waste (g/kWh): The radioactive waste, being fuel burnt in the reactor to be subsequently discharged as spent fuel. This is calculated on the basis of figures provided by the BEIS (details of these can be found on the Government website).
