The publication is designed to assist in understanding the contributions of specific fuels and sectors to GHG emissions associated with energy for each country globally. The database has been expanded in October 2021 to include estimates of total GHG emissions from energy and related indicators, including CO2, CH4 and N2O emissions from fuel combustion as well as fugitive emissions.
It is estimated that energy accounts for around three-quarters of total greenhouse gas (GHG) emissions globally. The IEA Greenhouse Gas Emissions from Energy dataset (upgrade of the former CO2 Emissions from Fuel Combustion) provides a full analysis of historical country-level emissions stemming from energy use, and has become an essential tool for analysts and policy makers.
Notes and references
The 2020 global emission figure is taken from the IEA Global Energy Review 2021.
In alignment with the 2006 IPCC Guidelines for greenhouse gas inventories, CO2 emissions from combustion of biofuels and renewable waste are not included in total emission from energy; however, associated non-CO2 (CH4 and N2O) emissions as well as all emissions from combustion of non-renewables waste are taken into account.
This is the decomposition of CO2 emissions from fuel combustion into four driving factors following the Kaya identity. For more information, please refer to the IEA GHG Emissions from Energy documentation.
