United States Environmentally-Extended Input-Output Model (USEEIO)

The United States Environmentally-Extended Input-Output Model (USEEIO) is a model developed by the U.S. EPA that links economic activity with environmental data to assess the life-cycle impacts of U.S. goods and services. It covers hundreds of product and industry categories, tracking resources, emissions, and waste to calculate environmental and economic indicators like carbon footprints. USEEIO supports decision-making for sustainability, life cycle assessments, and footprinting.
