Greenhouse Gas Reporting Program
GHGRP 2012: Reported Data
For reporting year (RY) 2012, over 8,000 facilities and suppliers reported to the greenhouse gas reporting program. Among these reporters, 7,809 facilities in nine industry sectors reported direct emissions to the atmosphere, with emissions totaling 3.13 billion metric tons carbon dioxide equivalent (CO2e), or about half of total U.S. greenhouse gas emissions. The facilities reported direct emissions of carbon dioxide, methane, nitrous oxide, and fluorinated gases. Additional facilities reported GHG quantities associated with products they supplied. Facilities also reported the quantity of carbon dioxide received for injection underground.

2012 Data Highlights Reported to GHGRP
All 2012 data presented here reflects data reported to the GHGRP as of 9/1/2013.
- The GHGRP represents about 85-90 percent of total U.S. emissions.
The GHGRP covers most, but not all U.S. GHG emissions. EPA prepares an annual Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) to track total national emissions of greenhouse gases for 1990 and each subsequent year. Learn more about differences between the Inventory and the GHGRP .
- Trends: Reported emissions decreased by 4.5 percent from 2011 to 2012.
2011 2012 Percent Change from Previous Year Number of facilities 7,607 7,809 +2.7% Emissions (million metric tons CO2e) 3,275 3,129 -4.5%
Total reported emissions decreased by 4.5% from 2011 to 2012. This decline was mostly related to a decrease in total reported emissions from power plants. Emissions from power plants decreased by 6.3% from 2011 to 2012. This is due to a switching from coal to natural gas for electricity generation and a slight decrease in electricity production.
- Power plants accounted for about one-third of total U.S. greenhouse gas emissions in 2012.
Power plants accounted for 2.09 billion metric tons CO2e, which represents 67% of emissions reported to the GHGRP and approximately one-third of total U.S. GHG emissions.
See the U.S. GHG Inventory report for more information about total U.S. emissions.
- 2012 Reporting: Location of direct-emitting facilities
About 10% of the facilities emitted 76% of 2012 reported emissions.
In 2012, the 770 largest-emitting facilities — those emitting more than 780,000 metric tons CO2e — accounted for almost 2.4 billion metric tons CO2e. These emissions represent about 76% of the total 3.13 billion metric tons CO2e reported.
These high-emitting facilities are mainly power plants, petroleum refineries, and facilities in the metals and chemicals industry sectors.
2012 Reported Emissions by State / Sector.
The chart above reflects total emissions from stationary sources reported to the GHGRP by state and sector. About half of total U.S. emissions are reported to the GHGRP by these emitters. The chart does not include emissions from the transportation or agricultural sectors and facilities whose emissions are below the 25,000 metric ton CO2e reporting threshold.
Suppliers: 2012 Reporting
Suppliers are those entities that supply into the economy products that if combusted, released, or oxidized emit GHGs into the atmosphere. Emissions associated with these fuels and industrial gases do not occur at the supplier’s facility but instead throughout the country, wherever the product is used. An example of this is gasoline, which is supplied into the U.S. economy by a relatively small number of entities and consumed by many individual vehicles throughout the country.
The majority of GHG emissions associated with the transportation, residential, and commercial sectors are accounted for by these suppliers.
The GHG quantity reported by suppliers might not always result in GHG emissions, and the emissions might not take place during the reporting year. However, the data from suppliers provide important information on the structure and flow of products through the economy, because these products could ultimately result in greenhouse gas emissions. In addition, reporting by fossil fuel and industrial gas suppliers can account for greenhouse gas emissions by the numerous low-emitting sources that are not required to report emissions under the GHGRP. Data reported by suppliers can be accessed through the suppliers section of FLIGHT.
