For reporting year (RY) 2011, approximately 8,000 facilities in nine industry sectors reported 3.3 billion tons carbon dioxide equivalent (CO2e) of direct emissions. The facilities reported direct emissions of carbon dioxide, methane, nitrous oxide, and fluorinated gases. Additional facilities reported GHG quantities associated with products supplied. Over 6,200 facilities across 29 source categories reported GHG data for RY2010. In 2011, 12 additional source categories began monitoring GHG data and reported GHG data for the first time in 2012. The addition of these 12 new source categories brings the total coverage of the GHGRP to 41 source categories. This table lists the nine industrial sectors and includes which of the 41 source categories are included in each sector.

EPA prepares the annual Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) report to track total national emissions of greenhouse gases. The Inventory presents national estimates of GHG emissions starting in 1990 and for each subsequent year. The GHGRP represents a subset of the national estimates and now includes approximately 85-90 percent of total U.S. GHG emissions with the addition of the 12 new source categories in 2011. More information on the U.S. Greenhouse Gas Inventory. Learn more about differences between the Inventory and the GHGRP.

2011 Data Highlights Reported to GHGRP

All 2011 data presented here reflects data reported to the GHGRP as of 1/16/13.

• 2011 Reporting: Location of direct-emitting facilities

  

  This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.

• About 4% of the facilities emitted 57% of 2011 reported emissions.

  

  In 2011, the 295 largest-emitting facilities — those emitting more than 2.5 million metric tons CO2e — accounted for almost 1.9 billion metric tons CO2e. These emissions represent about 57% of the total 3.3 billion metric tons CO2e reported.

  These high-emitting facilities are mainly power plants, petroleum refineries, and facilities in the metals and chemicals industry sectors.

• Power plants accounted for about 67% of direct emissions reported by stationary sources in 2011.

  

  Power plants accounted for 2.2 billion metric tons CO2e, which represents about 67% of the 3.3 billion metric tons CO2e reported for 2011.

  Emissions reported by power plants represent 33% of total U.S. GHG emissions. See the U.S. GHG Inventoryreport for more information about total U.S. emissions.

* Biogenic emissions are NOT included in the total emissions.
** Total reported emissions are less than 0.05 million metric tons CO2e.

Suppliers: 2011 Reporting

Suppliers are those entities that supply products into the economy which if combusted, released or oxidized emit greenhouse gases into the atmosphere. Emissions associated with these fuels and industrial gases do not occur at the supplier’s facility but instead throughout the country, where 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 may not always result in GHG emissions, and the emissions may 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 may ultimately result in greenhouse gas emissions. In addition, reporting by fossil fuel and industrial gas suppliers can account for greenhouse gas emissions by the many low-emitting sources that are not required to report emissions under the GHGRP. Emissions reported by suppliers can be accessed through the suppliers section of FLIGHT.

All non-CBI GHG data submitted to the GHGRP is now available on Envirofacts in a format that allows users to easily search, sort, and download data. Users have access to all reporting year 2010 data and the majority of reporting year 2011 data. The remaining reporting year 2011 data will be made available shortly.
