About IEA
The International Energy Agency (IEA) provides comprehensive electricity emission factors, which are essential for understanding the carbon footprint of electricity generation across different regions and energy sources. These factors assist governments, businesses, and researchers in measuring the environmental impact of electricity consumption and in developing strategies for reducing greenhouse gas emissions in the energy sector.

| Quality flag(s) | Partial factor The source reports emission factors for 2024 in CO2 only and does not include the impact of other GHGs. For a few countries, the same applies to other years as well (only a CO2 value is provided). In addition, transmission and distribution losses are also reported in CO2 only. |

EXIOBASE
EXIOBASE is a global, detailed Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and Input-Output Table (MR-IOT). It was developed by harmonising and detailing supply-use tables for a large number of countries, estimating emissions and resource extractions by industry. Subsequently, the country supply-use tables were linked via trade creating an MR-SUT and producing MR-IOTs from this. The MR-IOT can be used for the analysis of the environmental impacts associated with the final consumption of product groups. The EXIOBASE emission factors use basic prices. The basic price represents the initial cost set by a producer for a product or service, without additional fees like taxes or delivery costs (referred to as tax and transport margins). The values in the Climatiq Database might not be exactly the same as the ones you find on the EXIOBASE download page due to the prices used.
