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

New (April 2017): A preliminary version of this online data service has just been released.

The CO2 Emissions From Fuel Combustion annual data service contains time series of CO2  emissions from fossil fuel combustion, a major source of anthropogenic greenhouse gas emissions. Data are included for 35 OECD countries and for more than 100 non-OECD countries and regions.

Two databases are included:  2017 OECD and 2016 World.

The 2017 OECD edition (preliminary edition) includes OECD data from 1960 to 2015. Emissions were calculated using the IEA energy databases and the default methods and emissions factors from the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. This is in contrast to previous editions of this publication which were based on Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories.  Estimates of total CO2 emissions from fuel combustion may differ from those previously published due to revisions to underlying energy data submitted by countries, and also due to differences between the two sets of methodologies. For further information on the impact of these methodological changes, see the associated online documentation file.

Expanded Product Description for OECD 2017 preliminary edition


The 2016 World edition includes OECD and non-OECD countries and regions, with data from 1971 to 2014. Emissions were calculated using the IEA energy databases and the default methods and emissions factors from the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. Summary data for 1990, 2000, 2005 and 2010 for other greenhouse gases (CH4, N2O, HFCs, PFCs and SF6) as well as for COfrom non-energy related sources and gas flaring (counted as a fugitive emission) are also available.

Expanded Product Description for 2016 World edition (to be updated in September 2017)


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

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.
