Emissions Factors 2022
Annual GHG emission factors for World countries from electricity and heat generation
The Emissions Factors database includes the following indicators related to emissions from electricity and heat generation:
- CO2 emission factors from electricity and heat generation for world countries (in CO2 per kWh, 1990 to 2020).
- CO2 emission factors from electricity only generation (CHP electricity included) for world countries (in CO2 per kWh,1990 to 2020).
- Latest year emission factors for OECD countries and selected non-OECD countries based on provisional electricity generation data (in CO2 per kWh, 2021).
- Correction factors for CO2 emissions induced by electricity losses in the grid (in CO2 per kWh,1990 to 2020).
- Correction factors for CO2 emissions induced by electricity trade for OECD countries (in CO2 per kWh,1990 to 2020).
- CH4 and N2O emission factors from electricity generation (in CO2eq per kWh,1990 to 2020).
- Emission factors by fuel from direct combustion in other sectors than electricity and heat production (in CO2 per kg of fuel).
With the objective to increase the geographical coverage of the statistical information provided, the IEA has included in the 2022 edition CO2 emission factors for electricity and heat generation for a complementary set of over forty countries until 2020.
Frequently asked questions (FAQs)
Important licence information
Single user or multi-user?
Single and multi-user licences can be purchased directly online. These licences are exclusively for a single company or group and do not allow you to do work with third parties or put the data in a model for which the derived data would be visible or available to third parties (see below).
A single user licence is appropriate as long as only one person can access or view the data. If other users were able to view even the results of the calculations in a shared internal tool then you would need a licence to reflect all the users – if they are in different locations then a global licence would be needed.
We would therefore expect all multinationals to purchase the global licence (unlimited users, multiple locations).
Furthermore, if you intend to publish the results in your Annual Report then an (unlimited users, multiple locations) licence is required.
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 have questions please contact firstname.lastname@example.org.
The IEA reserves the right to check the customer's compliance with the terms and conditions.

Energy Projections of IEA Countries – with Extended Transitions Indicators
Projections for IEA members, accession countries and European Union collected directly from national administrations. The service is updated every year in November.
Greenhouse Gas Emissions from Energy
Annual time series of GHG emissions from energy, a major source of anthropogenic emissions. This database is updated twice a year. The April update includes all OECD and IEA family countries plus selected additional countries up to year-2. The final edition released in August includes data for all countries and regions up to year-2 and additional provisional data for OECD and selected countries up to year-1.
