CO2 Emissions from Fuel Combustion online data service 2017 edition - (expires 15 April 2018)

New!! (October 2017): A final version of this online data service has just been released.

World CO2 Emissions from Fuel Combustion database contains annual CO2 emissions from fuel combustion and related indicators for more than 140 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 186 countries/regions, generally from 1960 to 2015 (OECD) and from 1971 to 2015 (Non-OECD), unless specified differently at the country level. 

The CO2 Emissions from Fuel Combustion database is described in the following document: Expanded Product Description (2017 World edition)

The service is updated twice a year - in April with preliminary OECD data and in September with World data.

New! In 2017, a new product including indicators related to emissions from electricity and heat generation has been released: 

- 1990 to 2015 CO2 emission factors for electricity and heat generation for world countries (in CO2 per kWh of electricity and heat generated).
- 1990 to 2015 CO2 emission factors for electricity only generation (CHP electricity included) for world countries (in CO2 per kWh of electricity generated).
- 2016 provisional emission factors for OECD countries based on provisional electricity generation data (in CO2 per kWh of electricity generated).
- 1990 to 2015 correction factors for CO2 emissions induced by electricity losses in the grid (in CO2 per kWh of electricity consumed).
- 1990 to 2015 correction factors for CO2 emissions induced by electricity traded between countries for OECD countries (in CO2 per kWh of inland electricity).
- 1990 to 2015 CH4 and N2O emission factors for electricity generated (in CO2eq per kWh). 
- Emission factors for fuel consumption in other sectors than electricity and heat production (in CO2 per kg of fuel).

The methodology documentation and content description for the new indicators described above is available here

Please note that the CO2 emission factors from electricity generation are in a separate file and will be sent separately by e-mail after purchase. Also note that these emission factors cannot be downloaded using a data card.
