Source: EPA Greenhouse Gas Reporting Program, 2023 reporting year, sector-level emissions from data.epa.gov (fetched October 31, 2026). Direct emissions in metric tons CO2e as EPA totals them: emitter sectors only, biogenic CO2 reported separately. Covers facilities that report as direct emitters; most emit 25,000 t CO2e or more a year. Reference only.

Search any facility

emissionhub.cc's live search looks up any EPA-reporting facility by name and state, and the diligence brief turns a facility's reported tonnage into the checks an offset buyer would run. Pro ($4, 30-day pass) shows 15 facilities per search instead of 5.
