Note

The figures stated are Carbon Dioxide Equivalent Intensity, which means that for every Unit (kWh) of energy produced in a single quarter, an average of the figure shown equals the grams of CO2e emitted.

Emissions are those which are directly attributable to the local generation process and do not include emissions which are classed as indirect (e.g. Importation of fuel etc).

Guernsey Electricity Ltd also includes emissions which are associated with energy imported from EDF, in the figures stated. 

Emissions associated with imported energy, are calculated using figures published by EDF and include both direct and indirect emissions.
