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 five 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.

** Total reported emissions are less than 0.05 million metric tons CO 2 e.
1 The Southern California Gas Company - Aliso Canyon facility’s actual 2015 emissions were higher than those reported to the GHGRP. The GHGRP provides well-vetted average emission factors to calculate emissions. The facility followed these GHGRP calculation methods for 2015 reporting. Actual emissions differ from those reported due to an exceptional leak event. See California Air Resource Board’s Aliso Canyon Natural Gas Leak Exit webpage for more information.
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 representing 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: 1990-2014 contains information on all GHG emissions sources and sinks in the United States.

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 2015 reported data .

For 2015, 8,003 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 8,003 because facilities whose activities fall within more than one sector are counted multiple times.
In 2015, 3.05 billion metric tons CO 2 e were reported by direct emitters. The largest emitting sector was the Power Plant Sector with 2.0 billion metric tons CO 2 e, followed by the Petroleum and Natural Gas Systems Sector with 231 million metric tons (MMT) CO 2 e and the Refineries Sector with 176 MMT CO 2 e. This information, as well as average emissions per reporter, is shown in the following chart.

National level trends in greenhouse gas emissions are available through the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2014 . 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 increased by 1.0% from 2013 to 2014, based on the U.S. GHG Inventory. Between 2013 and 2014, emissions reported to the GHGRP increased by 0.5% (Table 4).
The U.S. GHG Inventory is not yet available for 2015. For sources reporting to the GHGRP, emissions increased by 0.5% from 2013 to 2014. Over the past five reporting years (2011-2015), GHGRP reported emissions have declined by 8.2%. This decline is caused primarily by a 11.3% decline in reported emissions by power plants since 2011.

Emissions by GHG
Carbon dioxide is the GHG emitted in the largest quantities. The 2.8 billion metric tons of CO 2 reported for 2015 represent 91.3% of the GHGs reported in 2015 a Methane emissions represent 7.2% of reported 2015 GHG emissions, N 2 O represents 0.9%, and fluorinated gases (HFCs, PFCs, SF 6 ) represent 0.7% (Figure 4).
a The Inventory of U.S. Greenhouse Gas Emissions And Sinks for 2015 is not yet available. In 2014, CO 2 represented 81% of total U.S. GHG emissions.

Geographic Distribution of Emissions
Figure 5: Location and Total Reported Emissions from GHGRP Facilities (2015)
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 CO 2 e 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 (2015)
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 (2015)
Eighty percent of reporting facilities had emissions less than 250,000 metric tons CO 2 e. In 2015, the 651 largest-emitting facilities—those emitting more than one million metric tons CO 2 e—accounted for almost 2.2 billion metric tons CO 2 e. These emissions represent 71.7% of the total 3.05 billion metric tons CO 2 e 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 (2015)
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.
Additional information on the methodologies that reporters use to determine GHG emissions
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.
