Greenhouse Gas Emissions

Understanding Global Warming Potentials

Greenhouse gases (GHGs) warm the Earth by absorbing energy and slowing the rate at which the energy escapes to space; they act like a blanket insulating the Earth. Different GHGs can have different effects on the Earth's warming. Two key ways in which these gases differ from each other are their ability to absorb energy (their "radiative efficiency"), and how long they stay in the atmosphere (also known as their "lifetime").

The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2). The larger the GWP, the more that a given gas warms the Earth compared to CO2 over that time period. The time period usually used for GWPs is 100 years. GWPs provide a common unit of measure, which allows analysts to add up emissions estimates of different gases (e.g., to compile a national GHG inventory), and allows policymakers to compare emissions reduction opportunities across sectors and gases.

CO2, by definition, has a GWP of 1 regardless of the time period used, because it is the gas being used as the reference. CO2 remains in the climate system for a very long time: CO2 emissions cause increases in atmospheric concentrations of CO2 that will last thousands of years.

Methane (CH4) is estimated to have a GWP of 28–36 over 100 years (Learn why EPA's U.S. Inventory of Greenhouse Gas Emissions and Sinks uses a different value.). CH4 emitted today lasts about a decade on average, which is much less time than CO2. But CH4 also absorbs much more energy than CO2. The net effect of the shorter lifetime and higher energy absorption is reflected in the GWP. The CH4 GWP also accounts for some indirect effects, such as the fact that CH4 is a precursor to ozone, and ozone is itself a GHG.

Nitrous Oxide (N2O) has a GWP 265–298 times that of CO2 for a 100-year timescale. N2O emitted today remains in the atmosphere for more than 100 years, on average.

Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are sometimes called high-GWP gases because, for a given amount of mass, they trap substantially more heat than CO2. (The GWPs for these gases can be in the thousands or tens of thousands.)

Frequently Asked Questions

Why do GWPs change over time?

EPA and other organizations will update the GWP values they use occasionally. This change can be due to updated scientific estimates of the energy absorption or lifetime of the gases or to changing atmospheric concentrations of GHGs that result in a change in the energy absorption of 1 additional ton of a gas relative to another.

Why are GWPs presented as ranges?

In the most recent report by the Intergovernmental Panel on Climate Change (IPCC), multiple methods of calculating GWPs were presented based on how to account for the influence of future warming on the carbon cycle. For this Web page, we are presenting the range of the lowest to the highest values listed by the IPCC.

What GWP estimates does EPA use for GHG emissions accounting, such as the Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) and the Greenhouse Gas Reporting Program?

The EPA considers the GWP estimates presented in the most recent IPCC scientific assessment to reflect the state of the science. In science communications, the EPA will refer to the most recent GWPs. The GWPs listed above are from the IPCC's Fifth Assessment Report, published in 2014.

The EPA's Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) complies with international GHG reporting standards under the United Nations Framework Convention on Climate Change (UNFCCC). UNFCCC guidelines now require the use of the GWP values for the IPCC's Fourth Assessment Report (AR4), published in 2007. The Inventory also presents emissions by mass, so that CO2 equivalents can be calculated using any GWPs, and emission totals using more recent IPCC values are presented in the annexes of the Inventory report for informational purposes.

Data collected by EPA's Greenhouse Gas Reporting Program is used in the Inventory, so the Reporting Program generally uses GWP values from the AR4. The Reporting Program collects data about some industrial gases that do not have GWPs listed in the AR4; for these gases, the Reporting Program uses GWP values from other sources, such as the Fifth Assessment Report.

EPA's CH4 reduction voluntary programs also use CH4 GWPs from the AR4 report for calculating CH4 emissions reductions through energy recovery projects, for consistency with the national emissions presented in the Inventory.

Are there alternatives to the 100-year GWP for comparing GHGs?

The United States primarily uses the 100-year GWP as a measure of the relative impact of different GHGs. However, the scientific community has developed a number of other metrics that could be used for comparing one GHG to another. These metrics may differ based on timeframe, the climate endpoint measured, or the method of calculation.

For example, the 20-year GWP is sometimes used as an alternative to the 100-year GWP. Just like the 100-year GWP is based on the energy absorbed by a gas over 100 years, the 20-year GWP is based on the energy absorbed over 20 years. This 20-year GWP prioritizes gases with shorter lifetimes, because it does not consider impacts that happen more than 20 years after the emissions occur. Because all GWPs are calculated relative to CO2, GWPs based on a shorter timeframe will be larger for gases with lifetimes shorter than that of CO2, and smaller for gases with lifetimes longer than CO2. For example, for CH4, which has a short lifetime, the 100-year GWP of 28–36 is much less than the 20-year GWP of 84–87. For CF4, with a lifetime of 50,000 years, the 100-year GWP of 6630–7350 is larger than the 20-year GWP of 4880–4950.

Another alternate metric is the Global Temperature Potential (GTP). While the GWP is a measure of the heat absorbed over a given time period due to emissions of a gas, the GTP is a measure of the temperature change at the end of that time period (again, relative to CO2).The calculation of the GTP is more complicated than that for the GWP, as it requires modeling how much the climate system responds to increased concentrations of GHGs (the climate sensitivity) and how quickly the system responds (based in part on how the ocean absorbs heat).

Global Emissions by Gas

At the global scale, the key greenhouse gases emitted by human activities are:

<img alt="Global GHG emissions by gas: 65% is from carbon dioxide fossil fuel use and industrial processes. 11% is from carbon dioxide deforestation, decay of biomass, etc. 16% is from methane. 6% is from nitrous oxide and 2% is from fluorinated gases." title="Global GHG emissions by gas: 65% is from carbon dioxide fossil fuel use and industrial processes. 11% is from carbon dioxide deforestation, decay of biomass, etc. 16% is from methane. 6% is from nitrous oxide and 2% is from fluorinated gases." height="448" width="448" class="right media-element file-medium right" typeof="foaf:Image" src="/sites/production/files/styles/medium/public/2016-05/global_emissions_gas_2015.png" />Source: IPCC (2014) Exit based on global emissions from 2010. Details about the sources included in these estimates can be found in the Contribution of Working Group III to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. Exit

Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. The way in which people use land is also an important source of CO2, especially when it involves deforestation. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture, and degradation of soils. Likewise, land can also remove CO2 from the atmosphere through reforestation, improvement of soils, and other activities.

Methane (CH4): Agricultural activities, waste management, energy use, and biomass burning all contribute to CH4 emissions.

Nitrous oxide (N2O): Agricultural activities, such as fertilizer use, are the primary source of N2O emissions. Biomass burning also generates N2O.

Fluorinated gases (F-gases): Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).

Black carbon is a solid particle or aerosol, not a gas, but it also contributes to warming of the atmosphere. Learn more about black carbon and climate change on our Causes of Climate Change page.

Global Emissions by Economic Sector

Global greenhouse gas emissions can also be broken down by the economic activities that lead to their production.[1]

<img alt="Pie chart showing emissions by sector. 25% is from electricity and heat production; 14% from transport; 6% from residential and commercial buildings; 21% from industry; 24% from agriculture, forestry and other land use; 10% from other energy uses." title="Pie chart showing emissions by sector. 25% is from electricity and heat production; 14% from transport; 6% from residential and commercial buildings; 21% from industry; 24% from agriculture, forestry and other land use; 10% from other energy uses." height="448" width="448" class="right media-element file-medium right" typeof="foaf:Image" src="/sites/production/files/styles/medium/public/2016-05/global_emissions_sector_2015.png" />Source: IPCC (2014); Exit based on global emissions from 2010. Details about the sources included in these estimates can be found in the Contribution of Working Group III to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. Exit

Electricity and Heat Production (25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.

Industry (21% of 2010 global greenhouse gas emissions): Greenhouse gas emissions from industry primarily involve fossil fuels burned on site at facilities for energy. This sector also includes emissions from chemical, metallurgical, and mineral transformation processes not associated with energy consumption and emissions from waste management activities. (Note: Emissions from industrial electricity use are excluded and are instead covered in the Electricity and Heat Production sector.)

Agriculture, Forestry, and Other Land Use (24% of 2010 global greenhouse gas emissions): Greenhouse gas emissions from this sector come mostly from agriculture (cultivation of crops and livestock) and deforestation. This estimate does not include the CO2 that ecosystems remove from the atmosphere by sequestering carbon in biomass, dead organic matter, and soils, which offset approximately 20% of emissions from this sector.[2]

Transportation (14% of 2010 global greenhouse gas emissions): Greenhouse gas emissions from this sector primarily involve fossil fuels burned for road, rail, air, and marine transportation. Almost all (95%) of the world's transportation energy comes from petroleum-based fuels, largely gasoline and diesel.

Buildings (6% of 2010 global greenhouse gas emissions): Greenhouse gas emissions from this sector arise from onsite energy generation and burning fuels for heat in buildings or cooking in homes. (Note: Emissions from electricity use in buildings are excluded and are instead covered in the Electricity and Heat Production sector.)

Other Energy (10% of 2010 global greenhouse gas emissions): This source of greenhouse gas emissions refers to all emissions from the Energy sector which are not directly associated with electricity or heat production, such as fuel extraction, refining, processing, and transportation.

(2015). Global, Regional, and National Fossil-Fuel CO2 Emissions. Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, U.S. Department of Energy, doi 10.3334/CDIAC/00001_V2015.

Global carbon emissions from fossil fuels have significantly increased since 1900. Since 1970, CO2 emissions have increased by about 90%, with emissions from fossil fuel combustion and industrial processes contributing about 78% of the total greenhouse gas emissions increase from 1970 to 2011. Agriculture, deforestation, and other land-use changes have been the second-largest contributors.[1]

Emissions of non-CO2 greenhouse gases have also increased significantly since 1900. To learn more about past and projected global emissions of non-CO2 gases, please see the EPA report, Global Anthropogenic Non-CO2 Greenhouse Gas Emissions: 1990-2020.

These data include CO2 emissions from fossil fuel combustion, as well as cement manufacturing and gas flaring. Together, these sources represent a large proportion of total global CO2 emissions.

Emissions and sinks related to changes in land use are not included in these estimates. However, changes in land use can be important: estimates indicate that net global greenhouse gas emissions from agriculture, forestry, and other land use were over 8 billion metric tons of CO2 equivalent,[2] or about 24% of total global greenhouse gas emissions.[3] In areas such as the United States and Europe, changes in land use associated with human activities have the net effect of absorbing CO2, partially offsetting the emissions from deforestation in other regions.

Note on emissions sector categories:

The global emission estimates described on this page are from the Intergovernmental Panel (IPCC) on Climate Change's Fifth Assessment Report. In this report, some of the sector categories are defined differently from how they are defined in the Sources of Greenhouse Gas Emissions page on this website. Transportation, Industry, Agriculture, and Land Use and Forestry are four global emission sectors that roughly correspond to the U.S. sectors. Energy Supply, Commercial and Residential Buildings, and Waste and Wastewater are categorized slightly differently. For example, the IPCC's Energy Supply sector for global emissions encompasses the burning of fossil fuel for heat and energy across all sectors. In contrast, the U.S. Sources discussion tracks emissions from the electric power separately and attributes on-site emissions for heat and power to their respective sectors (i.e., emissions from gas or oil burned in furnaces for heating buildings are assigned to the residential and commercial sector). The IPCC has defined Waste and Wastewater as a separate sector, while in the Sources of Greenhouse Gas Emissions page, waste and wastewater emissions are attributed to the Commercial and Residential sector.

Greenhouse Gas Emissions

Household Carbon Footprint Calculator

Many of our daily activities cause emissions of greenhouse gases. For example, we produce greenhouse gas emissions from burning gasoline when we drive, burning oil or gas for home heating, or using electricity generated from coal, natural gas, and oil. Greenhouse gas emissions vary among individuals depending on a person's location, habits, and personal choices. For example:

The quantity of greenhouse gas emissions from your home electricity use depends on the types of fuel your power plant uses to generate the electricity and the amount you use.

The quantity of greenhouse gases emitted from your furnace and boiler depends on the efficiency of these items, the size and insulation of your house, and the amount and type of fuel used.

The quantity of emissions from your car or truck depends on how much you drive, what your vehicle's fuel efficiency is, and how you drive (e.g., the amount of time spent idling in traffic).

In addition, the more recycling you do will reduce the amount of waste sent to landfills, as well as the greenhouse gas emissions that result from processing of raw materials.

Greenhouse Gas Reporting Program (GHGRP)

GHGRP Electrical Equipment Production and Use

 This source category includes electrical transmission and distribution systems and facilities that manufacture or refurbish electrical equipment.

The electrical transmission and distribution subsector consists of all electric transmission and distribution equipment insulated with or containing sulfur hexafluoride (SF6) or perfluorocarbons (PFCs) within an electric power system. This equipment includes but is not limited to gas-insulated substations; circuit breakers; switchgear, including closed-pressure and hermetically sealed-pressure switchgear; gas-insulated lines containing SF6 or PFCs; and gas containers such as pressurized cylinders, gas carts, electric power transformers, and other containers of SF6 or PFCs. Emissions occur during installation, use, servicing, and decommissioning of the equipment.

The electrical equipment manufacturing subsector includes facilities that manufacture or refurbish electrical equipment. At these facilities, emissions occur during equipment testing and filling.

2015 Total Reported Direct Emissions from Production and Use of Electrical Equipment Sector, by Subsector (as of 8/13/16).

Sum of percentages may not equal 100% due to independent rounding.

Greenhouse Gas Reporting Program (GHGRP)

GHGRP Industrial Profiles

EPA's Greenhouse Gas Reporting Program periodically produces detailed profiles of the various industries that report under the program. These profiles, available for download below, contain detailed analyses for each industry. These analyses include estimates of GHGRP coverage, emissions trends (including discussion), emissions by state, gas, and process, the number of reporters whose emissions fall above and below certain threshold values, and monitoring methods used. Each profile contains data from the indicated year back to 2011, and in some cases, 2010.

A simple summary of yearly data for each industry sector is available via the Data Highlights section of the GHGRP website, and data are available in interactive format via FLIGHT. Raw data are also available for download on the GHG Reporting Program Data Sets page.

Greenhouse Gas Reporting Program (GHGRP)

GHGRP Minerals

 The minerals sector consists of cement production, glass manufacturing, lime production, soda ash production, and any other mineral production facility operating under NAICS codes beginning with 327 (Non-metallic Mineral Product Manufacturing). Facilities under this sector transform mined or quarried non-metallic minerals — such as sand, gravel, stone, clay, and refractory materials — into products for intermediate or final consumption. Glass, cement, soda ash and lime facilities report both process emissions from the calcination of carbonate-based raw materials and GHG emissions from stationary fuel combustion sources. All other mineral production facilities report only GHG emissions from stationary fuel combustion sources. A small number of facilities in this sector collect CO2 either for use in their other production processes (e.g., sugar refining), to transfer to other users, or to sequester or otherwise inject underground. This sector includes the CO2 emissions reported for those processes.

2015 Total Reported Direct Emissions from Minerals, by Subsector (as of 8/13/16).

Sum of percentages may not equal 100% due to independent rounding.

Greenhouse Gas Reporting Program (GHGRP)

Greenhouse Gas Reporting Program and the U.S. Inventory of Greenhouse Gas Emissions and Sinks

Many industries and activities, large and small, emit greenhouse gases in the United States. These sources are found across all segments of the U.S. economy. EPA is responsible for characterizing greenhouse gas emissions using two complementary programs designed to help the public and policymakers understand both the sources and magnitude of these emissions.

The Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) is a document prepared annually by EPA, for over 20 years, that estimates the total greenhouse gas emissions across all sectors of the economy using national-level data.

The Greenhouse Gas Reporting Program (GHGRP)Â collects detailed emissions data from the largest greenhouse gas emitting facilities in the U.S.

While the Inventory provides high level perspective needed to understand the United Statesâ€™ total emissions or â€œcarbon footprint,â€? the GHGRP provides the detailed information that helps us better understand the sources and types of greenhouse gas emissions at individual facilities. This information can help industry identify opportunities for reduction and help communities identify nearby sources of greenhouse gas emissions. These data can be used to compare facilities or industries, track emissions from one year to the next, inform policy at the state and local levels, and provide important information to the finance and investment communities.

You can use the data from these two programs to answer common questions about U.S. greenhouse gas emissions. For example, the Inventory could help you find the contribution of the transportation sector, or the power sector, to total U.S. greenhouse gas emissions. The Greenhouse Gas Reporting program could help you find the biggest stationary sources of greenhouse gas emissions in your region.

Percent of U.S. Emissions Covered

The Inventory estimates the total greenhouse gas emissions across all sectors of the economy using national-level data such as fuel use. This includes estimates of greenhouse gas emissions from fossil fuel combustion, various industrial processes, and agricultural sources. The comprehensive greenhouse gas data presented in the Inventory comprise the official U.S. estimate of total national emissions that is submitted to the United Nations in accordance with the Framework Convention on Climate Change.

The GHGRP includes most, but not all, U.S. emissions. In general only large suppliers of greenhouse gas emitting products, or facilities that emit more than 25,000 metric tons of CO2 equivalent (CO2e) per year (roughly equivalent to the CO2 emitted from the burning of 131 rail cars of coal), are required to report their annual greenhouse gas emissions. Some entire sectors, such as the agricultural and land-use sectors, are not required to report. Over 8,000 facilities reported greenhouse gas data to EPA for 2014, covering approximately 85-90% of total U.S. greenhouse gas emissions.

Years of Data Available

The Inventory presents national greenhouse gas emissions estimates from 1990 and each subsequent year. Through the Inventory, EPA now has trend data for national greenhouse gas emissions for over 20 years.

The GHGRP is a more recent program, developed in response to Congressional mandate from 2008, so there are fewer years of data available. Annual GHG data for covered facilities in 29 industry types is available starting in 2010. Annual GHG data for covered facilities in an additional 12 industry types is available starting in 2011.

Geographic Information

Because the Inventory uses aggregate national data (such as fuel use) to estimate greenhouse gas emissions for most sources, it generally does not provide geographic information showing the location of the emissions.

In contrast, since the GHGRP data is collected from facilities, it is possible to map source location and aggregate reported emissions by county, state, or region, for industries who report direct emissions. The GHGRPâ€™s online Facility Level Information on GreenHouse gases Tool (FLIGHT) Â allows users to locate large emitters in their communities or state, and to view emissions by industry type or greenhouse gas.

Facility Map

This screenshot, showing the number of facilities in each geographic region, is an example of one of the many views that can be created through, FLIGHT, the online data publication tool.

	Â

Industry-Specific Information

A large amount of greenhouse gas emissions in the industrial sector come from the burning of fossil fuels for energy.Â  The Inventory has a comprehensive estimate of these emissions, but because it is based on aggregate national data for fuel use, the Inventory cannot show relative emissions from specific industries within the industrial sector. Likewise, the Inventory cannot show the largest emitting facilities within a specific industry.

The GHGRP data provides EPA with a new and invaluable opportunity to use facility-specific information to disaggregate the national estimate for emissions from fossil fuel combustion to specific industries such as refineries, metals production, and chemical manufacturing. In addition, it allows for comparison of emissions between facilities within the same industry. These data can be an important tool for businesses and other innovators to find cost- and fuel-saving efficiencies that reduce greenhouse gas emissions.

For a more detailed comparison of Inventory and GHGRP emissions data for the industrial sector, please see the fact sheet GHG Emissions by Industry â€“ GHGRP vs. U.S. GHG Inventory (PDF) (3pp, 244K).

Greenhouse Gas Reporting Program (GHGRP)

GHGRP Supplier Highlights

For reporting year (RY) 2015, over 900 suppliers of fuels and industrial gases reported to EPA’s Greenhouse Gas Reporting Program (GHGRP).

Suppliers do not report direct emissions, but instead report the quantity of GHGs that would be emitted if the fuels and industrial GHGs that they produce, import, or export each year were combusted, released, or oxidized. 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 GHG quantity reported by suppliers might not always result in GHG emissions, and the emissions might not take place during that particular reporting year. However, the data from suppliers provide important information on the structure and flow of products through the economy and these products may ultimately result in greenhouse gas emissions. In addition, data reported by fossil fuel and industrial gas suppliers can account for greenhouse gases emitted by the numerous sources that use these products but do not report under the GHGRP due to their low individual emissions (passenger vehicles, for example). Emissions reported by suppliers can be accessed through the suppliers section of FLIGHT.

For 2015, 961 suppliers submitted a GHG report. The majority of GHG emissions associated with the transportation, residential, and commercial sectors are accounted for by these suppliers.

Greenhouse Gas Reporting Program (GHGRP)

GHGRP Pulp and Paper

 The pulp and paper sector consists of facilities that produce market pulp or that manufacture pulp and paper. Facilities that have pulping processes report the GHG emissions from chemical recovery units, lime kilns, and stationary fuel combustion units. In addition to emissions from pulp production processes, the sector includes combustion emissions from facilities that produce paper products from purchased pulp, produce secondary fiber from recycled paper, convert paper into paperboard products, operate coating and laminating processes, print products (such as books, labels, business cards, stationery, and business forms), and perform support activities (such as data imaging, plate-making services, and bookbinding). Emissions from industrial landfills and industrial wastewater treatment at facilities in the pulp and paper sector are included in the waste sector.

2015 Total Reported Direct Emissions from Pulp and Paper, by Subsector (as of 8/13/16).

Sum of percentages may not equal 100% due to independent rounding.

Trend of Annual Reported GHG Emissions by Subsector (as of 8/13/16)

Emissions from the pulp and paper sector declined from 2012 to 2013 in part due to a change in the emission factors used to estimate GHG emissions from the combustion of spent pulping liquor and wood residuals. For more information, please click here.

Location and emissions range for each reporting facility in the pulp and paper sector (as of 8/13/16).

Greenhouse Gas Reporting Program (GHGRP)

Learn About the Greenhouse Gas Reporting Program (GHGRP)

The GHGRP (codified at 40 CFR Part 98) requires reporting of greenhouse gas (GHG) data and other relevant information from large GHG emission sources, fuel and industrial gas suppliers, and CO2 injection sites in the United States. This data can be used by businesses and others to track and compare facilities' greenhouse gas emissions, identify opportunities to cut pollution, minimize wasted energy, and save money. States, cities, and other communities can use EPA’s greenhouse gas data to find high-emitting facilities in their area, compare emissions between similar facilities, and develop common-sense climate policies.

A total of 41 categories of reporters are covered by the GHGRP. Facilities determine whether they are required to report based on the types of industrial operations located at the facility, their emission levels, or other factors. Facilities are generally required to submit annual reports under Part 98 if:

GHG emissions from covered sources exceed 25,000 metric tons CO2e per year.

Supply of certain products would result in over 25,000 metric tons CO2e of GHG emissions if those products were released, combusted, or oxidized.

The facility receives 25,000 metric tons or more of CO2 for underground injection.

Review a list of covered types of industrial operations and informational resources

Approximately 8,000 facilities are required to report their emissions annually. Total reported emissions from these facilities are about 3 billion metric tons CO2e, which is about 50 percent of total U.S. GHG emissions. Additional GHGs are accounted for by approximately 1,000 suppliers. In total, data covering 85-90 percent of U.S. GHG emissions are reported. A complete accounting of total U.S. GHG emissions is available through a separate EPA report, the U.S. Greenhouse Gas Inventory. Learn about the differences between the GHGRP and the Inventory.

Facilities in most source categories subject to Part 98 began reporting for the 2010 reporting year while additional types of industrial operations began reporting for reporting year 2011. GHGRP data are now publicly available for 2010 through 20151. Facilities calculate their emissions using methodologies that are specified at 40 CFR Part 98, and they report their data to EPA using the electronic Greenhouse Gas Reporting Tool (e-GGRT). Annual reports covering emissions from the prior calendar year are due by March 31st of each year. Once data are submitted, EPA conducts a multi-step verification process to ensure reported data are accurate, complete, and consistent.

The reported data are made available to the public in October of each year through several data portals accessible via the GHG Data Sets page.

FLIGHT: An interactive website with mapping features

Data Highlights: A high-level summary of reported data by industry.

GHGRP Petroleum and Natural Gas Systems

 This sector consists of the following industry segments of the petroleum and natural gas industry.

Onshore Production. Production of petroleum and natural gas associated with onshore production wells and related equipment.

Offshore Production. Production of petroleum and natural gas from offshore production platforms.

Natural Gas Processing. Processing of field quality gas to produce pipeline quality natural gas.

Natural Gas Transmission. Compressor stations used to transfer natural gas through transmission pipelines.

Underground Natural Gas Storage. Facilities that store natural gas in underground formations.

Natural Gas Distribution. Distribution systems that deliver natural gas to customers.

Liquefied Natural Gas (LNG) Import/Export. Liquefied Natural Gas import and export terminals.

LNG Storage. Liquefied Natural Gas storage equipment.

Other Petroleum and Natural Gas Systems. Stationary fuel combustion emissions from petroleum and natural gas source categories that are not otherwise listed.

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.
