The United States Environmentally-Extended Input Output database (USEEIO) is a comprehensive collection of processes that detail the environmental impacts of generic commodities in the United States.

It is based on Input-Output economic tables, which, as the name suggests compiles information about the input and output flows in dollars among industries (or commodities). By knowing the exchanges with nature from each commodity, total environmental impacts can be calculated for each commodity taking into account the interdependencies between commodities.

The original USEEIO models only take into account the production stage of processes. In Earthster we have enhanced USEEIO and therefore each model also contains distribution and use phase data, calculated using USEEIO's margins data and Earthster's Use phase data. We also have extended the number of models to 471 (from the original 422).

USD scale units correspond to January 2024 price levels and are derived from USD2012 using the U.S. BLS CPI Inflation Calculator, comparing the 2012 annual average CPI to the January 2024 CPI value.
