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
  • Emissions totaled 3.13 billion metric tons carbon dioxide equivalent (CO2e), about half of total U.S. greenhouse gas emissions.

Summary GHGRP data has been broken into several sections. Click the links below to expand each section.

All greenhouse gas data presented here reflect the information reported to EPA as of 09/01/2013. The reported emissions exclude biogenic CO2 unless otherwise noted and use the Global Warming Potentials from the IPCC’s Second Assessment Report.
  • Greenhouse Gas Reporting Program Background

    As directed by Congress, EPA’s Greenhouse Gas Reporting Program (GHGRP) collects annual greenhouse gas information from the top emitting sectors of the U.S. economy (Table 1). The GHGRP is the only dataset containing facility-level greenhouse gas (GHG) emissions data from major industrial sources across the United States. With three years of reporting for most sectors, GHGRP data are providing important new information on industrial emissions—showing variation in emissions across facilities within an industry, variation in industrial emissions across geographic areas, and changes in emissions over time at the sector and facility level. EPA is using this facility-level data to improve estimates of national greenhouse gas emissions, including using it to improve the U.S. Greenhouse Gas Inventory. The data are also being used to inform regulatory actions and voluntary emission reduction efforts.

    This document summarizes national industrial sector emissions and trends.

    a The data presented here reflects data reported to the GHGRP as of 9/1/2013.
    b Biogenic emissions are NOT included in the total emissions.
    ** Total reported emissions are less than 0.05 million metric tons CO2e.

    The GHGRP does not represent total U.S. GHG emissions, but provides facility level data for large sources of direct emissions, thus including the majority of U.S. GHG emissions. The GHGRP data collected from direct emitters represent about half of all U.S. emissions. When including greenhouse gas information reported by suppliers to the GHGRP, emissions coverage reaches approximately 85–90% (See Figure 1). The Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2012 contains information on all GHG emissions sources and sinks in the United States.

    Suppliers are those entities that supply products into the economy that, if combusted, released, or oxidized, would emit GHGs into the atmosphere. Emissions associated with these fuels and industrial gases do not occur at the supplier’s facility but instead occur throughout the country, wherever they are 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. This document focuses on data reported by direct emitters. Data reported by suppliers can be viewed through the suppliers section of the Facility Level Information on GreenHouse gases Tool (FLIGHT).

  • Reported Emissions

    All GHG emissions data, displayed in units of carbon dioxide equivalent (CO2e) reflect the global warming potential (GWP) values from the Intergovernmental Panel on Climate Change (IPCC), Climate Change 1995: The Science of Climate Change (Second Assessment Report (SAR), Cambridge, United Kingdom: Cambridge University Press). The SAR values also can be found in the version of Table A-1 to 40 CFR part 98, published in the Federal Register on October 30, 2009 (74 FR 56395).

    In 2012, 3.13 billion metric tons CO2e were reported by direct emitters. The largest emitting sector was the Power Plant Sector with 2.09 billion metric tons CO2e, followed by the Petroleum and Natural Gas Systems Sector with 217 million metric tons (MMT) CO2e and the Petroleum Refinery Sector with 173 MMT CO2e. This information, as well as average emissions per reporter, is shown in the following chart.

  • Emissions Trends

    National level trends in greenhouse gas emissions are available through the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2012. The Greenhouse Gas Reporting Program collects information from the largest stationary sources in the U.S. and provides nearly complete emissions coverage for many of the largest emitting industries. Discussion of the trend in reported emissions from 2010 (or in some cases 2011) to 2012 from individual industries that report to the GHGRP is included in the industry specific reports.

    While total U.S. emissions decreased by 1.8% from 2010 to 2011, emissions reported to the GHGRP increased over this period (Table 5). The increase occurred because 12 source categories were required to begin reporting for the first time in 2011. For these industries, 2011 is the appropriate base year for determining trends in reported emissions. Trends for other sectors can be determined using GHGRP data beginning in 2010 (Figure 3).

    Total U.S. emissions decreased by 3.4% from 2011 to 2012 based on the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2012 (April 2014). For facilities that reported to the GHGRP in 2011 and 2012, emissions declined by 4.5% (Table 5). This decline was driven by a 4.7% decline in emissions from power plants. In the two years since reporting began, emissions from power plants have decreased 10 percent.

  • Emissions by GHG

    Carbon dioxide represented 92.2% of the GHGs reported in 2012. The reported 2.89 billion metric tons represents about 54% of total U.S. CO2 emissions. Reported methane emissions were 192.0 MMT CO2e of methane, representing about 34%1 of total U.S. methane emissions. Facilities reported 29.5 MMT CO2e of N2O, representing about 7%1 of total U.S. N2O emissions. Finally, reported emissions of fluorinated gases (HFCs, PFCs, SF6) represent about 13%1 of U.S. emissions of these compounds.

  • Geographic Distribution of Emissions

    Figure 5: Location and Total Reported Emissions from GHGRP Facilities (2012)

    Map showing location and total reported emissions from GHGRP facilities, 2012.

    This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility. There are also facilities located in Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, and Guam.

    Readers can identify facilities in their state, territory, county, or city by visiting FLIGHT.

    Because it generally applies to facilities that emit greater than 25,000 metric tons CO2e per year, the GHGRP provides total reported emissions from large stationary sources in each state. Figure 6 shows the reported emissions in each state broken out by industrial sector.

  • Emissions Range

    The GHGRP provides a comprehensive dataset that can be used to determine the number of facilities at various emissions levels in many industry sectors. The GHGRP can also be used to determine the total GHG emissions from individual facilities, including emissions from fossil fuel combustion and other processes. This information is valuable for planning future policies. GHGRP data provide policy makers with a better understanding of the number of facilities and total emissions that would be covered by potential GHG reduction policies for various industries.

    Figure 7: Percentage of All Reporting Facilities at Various Emission Ranges (2012)

    Eighty percent of reporting facilities had emissions less than 250,000 metric tons CO2e. In 2012, the 650 largest-emitting facilities—those emitting more than 1,000,000 metric tons CO2e—accounted for almost 2.3 billion metric tons CO2e. These emissions represent 72.9% of the total 3.13 billion metric tons CO2e reported. These high-emitting facilities are mainly Power Plants, but also include Petroleum Refineries, and facilities in the Chemicals and Metals sectors.

    You can use FLIGHT to list and sort facilities based on total reported emissions and find the largest emitting facilities in the country or a specific state or county. This tool also allows you to sort facilities by specific industry types.

    Figure 8: Facility Emission Ranges (2012)

  • GHGRP Calculation Methods Used

    The GHGRP prescribes methodologies that must be used to determine GHG emissions from each source category. Reporters generally have the flexibility to choose among several methods to compute GHG emissions. The decision of which method to use may be influenced by the existing environmental monitoring systems in place and other factors. Reporters can change emission calculation methods from year to year and whin the same year, as long as they meet the requirements for use of the method selected.

  • Report Verification

    All reports submitted to EPA are evaluated by electronic validation and verification checks. If potential errors are identified, EPA will notify the reporter, who can resolve the issue either by providing an acceptable response describing why the flagged issue is not an error or by correcting the flagged issue and resubmitting their annual GHG report.
