Emissions Factors Package - SUBSCRIPTION

The IEA Emission Factors Package integrates the yearly IEA Emission Factors and the yearly IEA Life Cycle Upstream Emissions Factors databases. The data package is also updated on a quarterly basis by adding monthly and quarterly emission factors.

The excel file of this “Package”, integrating information from three different databases, includes a set of emission factors for electricity and electricity/heat generation, as described below:

From the IEA Emission Factors database:

• CO2 emission factors from electricity and heat generation for world countries (in CO2 per kWh, 1990 to 2023).

• CO2 emission factors from electricity only generation (CHP electricity included) for world countries (in CO2 per kWh, 1990 to 2023).

• Latest year (year 2024) emission factors for OECD countries and selected non-OECD countries based on provisional electricity generation data (in CO2 per kWh).

• Correction factors for CO2 emissions induced by electricity losses in the grid (in CO2 per kWh, 1990 to 2023).

• Correction factors for CO2 emissions induced by electricity trade for OECD countries (in CO2 per kWh, 1990 to 2023).

• CH4 and N2O emission factors from electricity generation (in CO2eq per kWh, 1990 to 2023). 

• Emission factors by fuel from direct combustion in other sectors than electricity and heat production (in CO2 per kg of fuel).

From the IEA Life Cycle Upstream Emission Factors database:

• Total upstream emission factors (in CO2eq per kWh, 2015 to 2023; and 2024 (provisional data for selected countries))

• Fuel-cycle emission factors (in CO2eq per kWh, 2015 to 2023; and 2024 (provisional data for selected countries))

• Life cycle adjustment factors for transmission and distribution losses (in CO2eq per kWh, 2015 to 2023)

Monthly and Quarterly Emission Factors are only available in this database:

• Monthly CO2 emission factors for electricity only generation for 52 countries (CHP electricity included) (in CO2 per kWh, January 2015 to December 2025).

• Quarterly CO2 emission factors for electricity only generation for 52 countries (CHP electricity included) (in CO2 per kWh, 1st quarter of 2015 to 4th quarter of 2025). 

A total greenhouse emissions per kwh of activity or electricity generated is also only available in this database. This factor is a proxy of a global emission factor related to electricity-only generation from national grids, including life cycle factors and transmission and distribution adjustments.

Important licence information

For clients who have already purchased the global (unlimited users, multiple locations) licence for either the IEA Emission Factors 2025 or the IEA Life Cycle Upstream Emission Factors databases, this package can be purchased at a discount. For more information please contact datasales@iea.org.

Do I need a contract or permission?

If you are doing work for clients, i.e. third parties, e.g. calculating or verifying their carbon footprint you need to enter into a separate Agreement and pay a fee as this usage is not permitted under our standard terms and conditions. 

If you intend to use the data in any type of modelling for the purpose of creating derived data or derived products, and any services to distribute or display such derived products you need to sign an Agreement and pay a fee.

If you intend to have such usage or any usage falling outside of our Terms and Conditions, please fill in this questionnaire and return it to datasales@iea.org.

The IEA reserves the right to check the customer's compliance with the terms and conditions.
