The U.S. Environmental Protection Agency today released its latest annual Inventory of U.S. Greenhouse Gas Emissions and Sinks (GHG Inventory), which presents an overview of annual greenhouse gas emissions from 1990 to 2022. Net U.S. greenhouse gas emissions were 5,489 million metric tons of carbon dioxide equivalent in 2022, a 1.3% increase in emissions from 2021. EPA said the increase is mostly due to higher energy use in 2022, reflecting the continued recovery in economic activity following the height of the coronavirus pandemic. Crucially, emissions have declined 17% overall since 2005, which reflects the combined impacts of several factors, including energy market trends, technological changes including energy efficiency improvements, and the carbon intensity of energy fuel choices. However, the transportation sector was flat.
