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.
