US Environmentally-Extended Input-Output (USEEIO) Technical Content
Technical Considerations, Current Versions, and Other Resources
US Environmentally-Extended Input-Output (USEEIO) models are combined economic-environmental models. The models use data on inputs to and outputs from industries and their final consumption and value added in the form of input-output tables from the Bureau of Economic Analysis (BEA). These tables are paired with environmental data on resource use and releases of pollutants from various public sources in the form of satellite tables, as well as indicators of potential environmental and economic impact, using standard algorithms from input-output analysis.

^ These models incorporate import emission factors to represent RoW rather than explicitly as a model region
% only 2020 year models are available on API
* These USEEIO models use data from a variety of years that are adjusted in procedures to harmonize them that are described in the documentation and therefore the models do not represent a single year.
