On June 24, 2025, the Environmental Protection Agency (EPA) announced that it would stop updating the U.S. Environmentally-Extended Input-Output (USEEIO) database. USEEIO combines environmental and economic data to calculate emissions factors for a range of goods and services, and is used by hundreds of companies to calculate the greenhouse gas emissions generated in their supply chains.
Damien Lieber, a senior manager at an environmental consulting firm, called the decision to stop updating USEEIO “a major setback for corporate climate action and reporting” and described the database as “one of the most important data sets available — if not the most important — for estimating value chain emissions.”
The creator of the database, Dr. Wesley Ingwersen, was one of the 144 EPA employees placed on administrative leave after signing onto a letter accusing the Trump administration of undermining federal science. He worked in the agency’s Office of Research and Development, which the administration announced in July would be eliminated.
