EPA Releases 2023 Data Collected Under Greenhouse Gas Reporting Program

WASHINGTON – Today, Oct. 15, the U.S. Environmental Protection Agency (EPA) released 2023 greenhouse gas data collected under the EPA’s Greenhouse Gas Reporting Program.

In 2023, reported direct emissions of greenhouse gases from large stationary sources, representing approximately 50% of total U.S. emissions, were down by approximately 4% from 2022.

More than 8,100 industrial facilities reported greenhouse gas emissions in 2023 to the EPA. The data show that in 2023:

• Power plants were the largest stationary source of U.S. greenhouse gas emissions, with 1,320 facilities emitting approximately 1.5 billion metric tons of carbon dioxide. Reported power plant emissions decreased by 7.2% between 2022 and 2023. There is a 33.8% decrease in emissions since 2011, reflecting the long-term shifts in power sector fuel stock from coal to natural gas.

• Petroleum and natural gas systems were the second largest stationary source of reported emissions, reporting 322 million metric tons of greenhouse gas emissions. Reported emissions for 2023 were 1.4% higher than in 2022, and 16.4% higher than 2016. (2016 is the earliest year of comparable data for this sector, as new industry segments began reporting that year.)

• Reported direct emissions from other large sources in the industrial and waste sectors were a combined 785 million metric tons of greenhouse gas emissions in 2023, down 1.1% from 2022, and down 10.3% since 2011. These are other direct emission sources reporting to the GHGRP, other than power plants and petroleum and natural gas facilities.

From 2011 to 2023, total reported GHG emissions from large facilities decreased by approximately 22%, driven by a decrease in power plant emissions.

This decline occurred despite the fact that after 2016, the program began tracking additional sources.

The reporting year 2023 Greenhouse Gas Reporting Program Data does not yet reflect the impact of several rules the EPA issued in 2024 to tackle methane emissions from the oil and gas sector and improve data quality.

These actions include standards to reduce methane and other harmful air pollution from new and existing oil and natural gas operations; a final rule under the Greenhouse Gas Reporting Program to strengthen, expand, and update methane emissions reporting requirements for oil and gas operations to help close the gap between observed and reported emissions; and other amendments to improve Greenhouse Gas Reporting Program data.

EPA will be holding an informational webinar to demonstrate its internet-based greenhouse gas data publication tools, including new features and a tutorial on common searches, on Oct. 23.

The EPA will hold an additional webinar on Oct. 25 to demonstrate the data publication tools and searches as they relate to the oil and gas sector (also known as subpart W).

This is the fourteenth year of data collection for most sectors under the GHGRP. As directed by Congress, EPA collects annual, facility-level emissions data from major industrial sources, including power plants, oil and gas production, iron and steel mills, and landfills.

GHGRP also collects activity data from upstream fossil fuel and industrial gas suppliers. More than 8,100 direct emitters and suppliers report GHG data to the GHGRP.

Data reported from both direct emitters and upstream suppliers combined cover 85% to 90% of total U.S. GHG emissions.

A complete accounting of total U.S. GHG emissions across all sectors of the economy using national-level data is available through a separate EPA report, the Inventory of U.S. Greenhouse Gas Emissions and Sinks.
