GHGRP Reported Data
All greenhouse gas data presented here reflect the information reported to EPA as of August 19, 2018. The reported emissions exclude biogenic CO2. GHG data displayed are in units of carbon dioxide equivalent (CO2e) and reflect the global warming potential (GWP) values from Table A-1 Exit, which is generally based on the Intergovernmental Panel on Climate Change (IPCC)’s Fourth Assessment Report (AR4) Exit. The GWPs for some fluorinated GHGs that did not have GWPs in the AR4 are from the IPCC’s Fifth Assessment Report.
For reporting year (RY) 2017, over 8,000 facilities and suppliers reported to the greenhouse gas reporting program. Among these reporters,
- 7,544 facilities in nine industry sectors reported direct emissions.
- Reported direct emissions totaled 2.91 billion metric tons carbon dioxide equivalent (CO2e), about half of total U.S. greenhouse gas emissions;
- 967 suppliers of fossil fuels and industrial gases reported; and
- 98 facilities reported injecting CO2 underground.

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 seven consecutive 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 in the U.S. Greenhouse Gas Inventory.
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: 1990-2016 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 2017 reported data.

Emissions Trends
National level trends in greenhouse gas emissions are available through the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2016. 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 1.9 percent from 2015 to 2016, based on the U.S. GHG Inventory. For sources reporting to the GHGRP, excluding emissions from the oil and gas sector (which reported new source in 2016), emissions decreased by 4.0 percent from 2015 to 2016.
The U.S. GHG Inventory is not yet available for 2017. For sources reporting to the GHGRP, emissions decreased by 2.6 percent from 2016 to 2017. Over the past seven reporting years (2011-2017), GHGRP reported direct emissions from sectors other than oil and gas (also excluding suppliers) declined by 15.1 percent. This decline is primarily caused by a 19.3 percent decline in reported power plant emissions since 2011.

Emissions by GHG
Carbon dioxide is the GHG emitted in the largest quantities. The 2.6 billion metric tons of CO2 reported for 2017 represent 90.7 percent of the GHGs reported in 2017a. Methane emissions represent 7.7 percent of reported 2017 GHG emissions, N2O represents 0.9 percent, and fluorinated gases (HFCs, PFCs, SF6) represent 0.6 percent (Figure 4).
aThe Inventory of U.S. Greenhouse Gas Emissions And Sinks for 2017 is not yet available. In 2016, CO2 represented 82 percent of total U.S. GHG emissions.
Figure 4: Direct Emissions by GHG (2017)
The table below lists the primary sectors emitting each GHG.
Greenhouse Gas | Source Categories Contributing Most to Emissions1 | Sectors Contributing Most to Emissions |
---|---|---|
CO2 | Electricity Generation (D), Stationary Combustion (C) | Power Plants, Petroleum and Natural Gas Systems |
CH4 | Petroleum & Natural Gas Systems (W), Municipal Landfills (HH) | Petroleum and Natural Gas Systems, Waste |
N2O | Nitric Acid Production (V), Adipic Acid Production (E), Electricity Generation (D) | Chemicals, Power Plants |
SF6 | SF6 from Electrical Equipment (DD), Electronics Manufacturing (I) | Other, Metals |
NF3 | Electronics Manufacturers (I), Fluorinated Gas Production (L) | Other, Chemicals |
HFCs | HCFC–22 Production and HFC–23 Destruction (O), Fluorinated Gas Production (L) | Chemicals |
PFCs | Electronics Manufacturers (I), Fluorinated Gas Production (L) | Chemicals, Other |
1 These source categories account for 75 percent or more of the reported emissions of the corresponding GHG. The subpart under which the emissions were reported is shown in parentheses.
Geographic Distribution of Emissions
Figure 5: Location and Total Reported Emissions from GHGRP Facilities (2017)
This map shows the locations of direct-emitting facilities. The size of a circle corresponds to the quantity of emissions reported by that facility.
Readers can identify facilities in their state, territory, county, or city by visiting the Facility Level Information on GreenHouse gases Tool (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 (2017)

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.
Figure 7: Percentage of All Reporting Facilities at Various Emission Ranges (2017)
Eighty percent of reporting facilities had emissions less than 250,000 metric tons CO2e. In 2017, the 613 largest-emitting facilities—those emitting more than one million metric tons CO2e—accounted for 2.05 billion metric tons CO2e. These emissions represent 70.4 percent of the total 2.91 billion metric tons CO2e reported. These high-emitting facilities are mainly power plants, but they also include facilities in all other direct emitter sectors.
You can use FLIGHT to list and sort facilities based on total reported emissions. This tool also allows you to sort facilities by specific industry types.
Figure 8: Facility Emission Ranges (2017)
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
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.

The U.S. Greenhouse Gas Inventory contains information on all sources of GHG emissions and sinks in the United States from 1990 to 2016.
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.
