- 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 large industrial sources across the United States. With four 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.

The GHGRP does not represent total U.S. GHG emissions, but provides facility level data for large sources of direct emissions, thus representing 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 to the GHGRP by suppliers, 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.
Learn more about the differences between the Inventory and the GHGRP.
Figure 1: U.S. Greenhouse Gas Inventory and the Greenhouse Gas Reporting Program
Suppliers report the quantity of GHGs that would be emitted if the fuels and industrial GHGs that they place into the economy each year are used/released. Reporting by suppliers helps account for the greenhouse gas emissions by the numerous low-emitting sources that are not required to report emissions under the GHGRP (e.g., mobile sources, residential sources). Learn more about suppliers and their 2013 reported data.

- Who reports?
For 2013, 7,865 direct emitters submitted a GHG report. The Petroleum and Natural Gas Systems sector had the largest number of reporting facilities, followed by the Waste Sector and the Power Plants Sector. Among suppliers, Suppliers of Natural Gas and Natural Gas Liquids had the largest number of reporting facilities.

1 Totals sum to more than 7,879 because facilities whose activities fall within more than one sector are counted multiple times.
- Reported Emissions
In 2013, 3.18 billion metric tons CO2e were reported by direct emitters. The largest emitting sector was the Power Plant Sector with 2.1 billion metric tons CO2e, followed by the Petroleum and Natural Gas Systems Sector with 224 million metric tons (MMT) CO2e and the Petroleum Refinery Sector with 177 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 is different from the U.S. GHG Inventory in that it collects information from the largest stationary sources in the U.S. and provides nearly complete emissions coverage for many of the largest emitting industries. Trends in emissions reported for individual industries are discussed in the industry-specific reports.
Total U.S. emissions decreased by 3.4% from 2011 to 2012, based on the U.S. GHG Inventory. Between 2011 and 2012, emissions reported to the GHGRP declined by 4.5% (Table 4). This decline was driven by a 4.7% decline in emissions from power plants.
The U.S. GHG Inventory is not yet available for 2013. For sources reporting to the GHGRP, emissions increased by 0.62% from 2012 to 2013; this increase was driven by a similar increase in power plant emissions. Over the past three reporting years (2011-2013), GHGRP reported emissions have declined by 3.9%. This decline is caused primarily by a 5.4% decline in reported emissions by power plants. Since 2010, emissions from power plants have decreased by 9.8%.

- Emissions by GHG
Carbon dioxide is the GHG emitted in the largest quantities. The 2.9 billion metric tons of CO2 reported for 2013 represent 91.4% of the GHGs reported in 2013.a Methane emissions represent about 7% of reported 2013 GHG emissions, N2O represents about 0.8%, and fluorinated gases (HFCs, PFCs, SF6) represent about 0.7% (Figure 4).
aThe Inventory of U.S. Greenhouse Gas Emissions And Sinks for 2013 is not yet available. In 2012, CO2 represented 54% of total U.S. GHG emissions.

- Geographic Distribution of Emissions
Figure 5: Location and Total Reported Emissions from GHGRP Facilities (2013)
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.
Figure 6: Direct GHG Emissions by State and Sector (2013)
- 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 (2013)
Eighty percent of reporting facilities had emissions less than 250,000 metric tons CO2e. In 2013, the 629 largest-emitting facilities—those emitting more than one million metric tons CO2e—accounted for almost 2.3 billion metric tons CO2e. These emissions represent 84.8% of the total 3.18 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 within the same year, as long as they meet the requirements for use of the method selected.
For additional information on the methodologies that reporters use to determine GHG emissions, please read the GHGRP Methodology Factsheet.
- 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.
For additional information describing EPA’s verification process in more details, please read the GHGRP Verification Factsheet.

The U.S. Greenhouse Gas Inventory contains information on all sources of GHG emissions and sinks in the United States from 1990 to 2012.
All GHG emissions data reflect the global warming potential (GWP) values from the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (Climate Change 2007: The Physical Science Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change [Core Writing Team, Pachauri, R.K. and Reisinger, A. (eds)]. IPCC, Geneva, Switzerland, 2007). The AR4 values also can be found in the current version of Table A-1 in subpart A of 40 CFR part 98.
