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.

Cornerstone is a sustainability data initiative that now maintains the US Environmentally-Extended Input-Output (USEEIO) family of models, originally developed by the US Environmental Protection Agency (EPA). USEEIO provides open emission factors across more than 400 sectors of the US economy and is widely used for Scope 3 corporate accounting, policy analysis, and academic research.

The United Nations Economic Commission for Europe (UNECE) is one of the regional commissions of the United Nations, focused on improving economic relationships between European countries and enhancing cooperation for sustainable development. Among its various publications is the document on Integrated Life-cycle Assessment of Electricity Sources, which provides comprehensive emission factors for different electricity generation methods.
