• 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 CO₂e.

  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 Exitwebpage 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.

  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 2015 reported data.

• Reported Emissions

  In 2015, 3.05 billion metric tons CO₂e were reported by direct emitters. The largest emitting sector was the Power Plant Sector with 2.0 billion metric tons CO₂e, followed by the Petroleum and Natural Gas Systems Sector with 231 million metric tons (MMT) CO₂e and the Refineries Sector with 176 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: 1990-2014. 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 CO₂ reported for 2015 represent 91.3% of the GHGs reported in 2015^a Methane emissions represent 7.2% of reported 2015 GHG emissions, N₂O represents 0.9%, and fluorinated gases (HFCs, PFCs, SF₆) represent 0.7% (Figure 4).

  ^a The Inventory of U.S. Greenhouse Gas Emissions And Sinks for 2015 is not yet available. In 2014, CO₂ represented 81% of total U.S. GHG emissions.

  Figure 4: Direct Emissions by GHG (2015)

  

  The table below lists the primary sectors emitting each GHG.

  Table 6: Largest Sources of GHG Emissions

  Greenhouse Gas	Source Categories Contributing Most to Emissions1	Sectors Contributing Most to Emissions
  CO2	Electricity Generation (D), Stationary Combustion (C)	Power Plants
  CH4	Municipal Landfills (HH), Petroleum & Natural Gas Systems (W)	Waste, Petroleum & Natural Gas Systems
  N2O	Nitric Acid Production (V), Electricity Generation (D), Adipic Acid Production (E)	Chemicals, Power Plants
  SF6	SF6 from Electrical Equipment (DD), Electronics Manufacturing (I), Magnesium Production (T)	Other, Metals
  NF3	Electronics Manufacturers (I), Fluorinated Gas Production (L)	Other
  HFCs	HCFC–22 Production and HFC–23 Destruction (O), Fluorinated Gas Production (L)	Chemicals
  PFCs	Electronics Manufacturers (I), Aluminum Production (F)	Metals, Other

  ¹ These source categories account for 75% 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 (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 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 (2015)

  

  Eighty percent of reporting facilities had emissions less than 250,000 metric tons CO₂e. In 2015, the 651 largest-emitting facilities—those emitting more than one million metric tons CO₂e—accounted for almost 2.2 billion metric tons CO₂e. These emissions represent 71.7% of the total 3.05 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.

• 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.

• 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.
