The IEA is disseminating this database including life cycle emission factors corresponding to national electricity grids. The database aims to assess and compile reliable data to provide a global harmonized database on an annual basis.
This database complements the IEA Emissions Factors 2026 database which includes emission factors corresponding to direct combustion at the point of electricity generation.
Data is published in an excel format and includes three main sheets with a set of life cycle emission factors corresponding to electricity generation. The factors are described below:
Total upstream emission factors [in CO2eq per kWh, 2015 to 2024; and 2025 (provisional data for selected countries)](Sheet Total upstream factors)
Correspond to the total upstream emissions intensity associated with the national electricity generation. The factors are computed using the overall life cycle footprint of the electricity generation technologies/fuels excluding direct emissions from combustion of the fuels at the generation point weighted by their respective shares in the generation mix.
Fuel-cycle emission factors [in CO2eq per kWh, 2015 to 2024; and 2025 (provisional data for selected countries)] (Sheet Fuel-cycle factors)
Correspond to the fuel-cycle emissions intensity associated with the national electricity generation. The factors are computed using the life cycle emissions intensity corresponding to fossil fuels, uranium and biofuels fuel-cycles weighted by the respective shares of all fuels/technologies in the generation mix. The non-fuel cycle life cycle emissions and the direct emissions from combustion of the fuels at the generation point are excluded.
Life cycle adjustment factors for transmission and distribution losses (in CO2eq per kWh, 2015 to 2024) (Sheet Life cycle T&D factors)
Include the emission intensities associated with the transmission and distribution losses of electricity in the grid developed from a life cycle perspective.
The IEA welcomes feedback on content, format and methodologies corresponding to this database.
