CEDA (Comprehensive Environmental Data Archive) is a spend-based emission factor database with 60,000 factors across 400 industries and 148 countries, used for Scope 3 reporting, LCA analyses, and sustainable procurement, and is maintained by Watershed and available for free as “Open CEDA.”

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).

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.
