CO2 Emissions from Fuel Combustion

New! February 2021: Release of first update of 2021 edition

This data service contains annual time series of CO2 emissions from fossil fuel combustion, a major source of anthropogenic greenhouse gas emissions.

January 2021: subscribers now get a full 12 months access no matter when they subscribe.

New!!  February 2021: Early 2021 release

The CO2 Emissions from Fuel Combustion database contains annual CO2 emissions from fuel combustion and related indicators for 190 countries plus regional aggregates. Emissions were calculated using IEA energy databases and the default methods and emission factors given in the 2006 GLs for National Greenhouse Gas Inventories. This edition includes annual data for 190 countries/regions, generally from 1960 (OECD) and from 1971 (Non-OECD), unless specified differently at the country level.

This service is updated three times a year with a progressively broader geographical coverage – in FebruaryApril and July - the final edition with global data.


In an effort to provide users with more timely information, with the February 2021 edition of the CO2 emissions from fuel combustion database, the IEA is releasing CO2 emissions for those selected economies of the OECD and beyond (including all IEA Association countries), for which data up to 2019 have been already received and validated.

Expanded Product Description - Early release (published February 2021)


The July edition includes complete time series of CO2 emissions from fuel combustion by source and sector for all countries and regions up to the year 2018, based on the 2020 IEA World energy balances.

With the objective to provide users with more timely and more comprehensive high-quality information, with the 2020 release the database was also expanded to include estimates of:

  • Emissions from fuel combustion for the latest year (2019) for all OECD countries and regions, India and China;
  • Emissions from electricity and heat production for the latest year (2019) for over seventy-five countries;
  • Total and sectoral emissions for a complementary set of over sixty countries based on additional sources;
  • Fugitive emissions of carbon dioxide and methane by country based on IEA information;
  • Emissions from fuel combustion starting in 1751 for the world and selected regions.

Expanded Product Description - World (published July 2020)

For carbon emissions by end use please see the Energy Efficiency Indicators database.


Important note: the CO2 emission factors from electricity generation are no longer included in this data service.  They are sold as a separate product entitled Emissions Factors.
