US Emissions Pass Pandemic Level

By Simon Johns - Apr 14, 2023

A rebound in economic activity since the COVID-19 pandemic in the United States has pushed net greenhouse gas emissions past the level in 2020, found the US Environmental Protection Agency.

In its 30th Inventory of US Greenhouse Gas Emissions and Sinks, the EPA found that emissions reached 5.59 billion metric tons of carbon dioxide equivalent in 2021. While this is a 6% increase over 2020, emissions have declined overall by 17% since 2005, the EPA found.

Ongoing energy trends, including greater uptake of renewables and improved efficiency of technology such as electronics and engines have contributed to the downward trend.

“For 30 years EPA has worked with researchers, federal partners, and stakeholders to produce a detailed and complete inventory of U.S. greenhouse gas emissions and sinks,” said Joseph Goffman, principal deputy assistant administrator for the Office of Air and Radiation, in a press release. rreleased on Thursday.

The inventory shows national greenhouse gas emissions from 1990 to 2021. It covers seven key greenhouse gases, including carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and nitrogen trifluoride.
