How did COVID influence the trend in emissions from 2019 to 2020?
National level trends in greenhouse gas emissions are available through the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2020. 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 9.0% from 2019 to 2020, based on the U.S. GHG Inventory. For sources reporting to the GHGRP, emissions decreased by 9.0% from 2019 to 2020.
The U.S. GHG Inventory is not yet available for 2021. For sources reporting to the GHGRP, emissions increased by 4.1% from 2020 to 2021. Over the past eleven reporting years (2011-2021), GHGRP reported direct emissions from sectors other than oil and gas (also excluding suppliers) declined by 22.6%. This decline is primarily caused by a 29% decline in reported power plant emissions since 2011.
