Both EPA and the Energy Information Administration collect greenhouse gas data.

EPA tracks U.S. greenhouse gas emissions and their sources through two complementary programs: the Inventory of U.S. Greenhouse Gas Emissions and Sinks (the Inventory), and the Greenhouse Gas Reporting Program (GHGRP). They collect data on all greenhouse gases: CO2, Methane, Nitrous Oxide, and Fluorinated GHGs.

The Inventory data are calculated by EPA, include all emissions sources and forestry sinks, which reflect 100% of total U.S. emissions, and are parsed nationally by sector.

GHGRP data are reported by over 8,000 facilities. They include only large emitters (>25,000 MTCO2e/Year), which reflect 85-90% of total U.S. emissions. Data are parsed at the national, state, local, sector, and facility-specific level.

EIA's greenhouse data include ONLY carbon dioxide emissions from energy and industry, by consuming sector (residential, commercial, industrial, transportation, electric power), and other emissions.

About the Data

The Facility Level Information on Greenhouse Gases Tool (FLIGHT) gives you access to greenhouse gas data reported to EPA by large emitters, facilities that inject CO2 underground, and suppliers of products that result in GHG emissions when used in the United States. FLIGHT allows you to view data in several formats including maps, tables, charts and graphs for individual facilities or groups of facilities. You can search the data set for individual facilities by name or location or filter the data set by state or county, fuel type, industry sectors and sub-sectors, annual facility emission thresholds, and greenhouse gas type. You can also compare emission trends over time and download data generated as a product of your analyses.

Greenhouse Gas Reporting Program Data is also available through Envirofacts.

Reports Using GHGRP Data

For reporting year (RY) 2015, over 8,000 facilities and suppliers reported to the greenhouse gas reporting program. Among these reporters,

• 8,003 facilities in nine industry sectors reported direct emissions.
• Reported direct emissions totaled 3.05 billion metric tons carbon dioxide equivalent (CO2e), about half of total U.S. greenhouse gas emissions.
• 961 suppliers reported.
• 101 facilities reported injecting CO2 underground.

The reports below provide summaries of the data as a whole and for particular industrial sectors.

This annual report provides a comprehensive accounting of total greenhouse gas emissions for all man-made sources in the United States. The gases covered by the Inventory include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. The Inventory also calculates carbon dioxide emissions that are removed from the atmosphere by “sinks,” e.g., through the uptake of carbon and storage in forests, vegetation, and soils.
