The USGS recently released a new report analyzing greenhouse gas emissions  including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)  associated with U.S. federal lands. Published as a follow-up to an earlier USGS 2018 report, it incorporates the latest data and methodologies, expanding the timeframe of analysis from 2005 to 2022 while providing updated estimates of ecosystem carbon emissions and sequestration. Given that U.S. federal lands are approximately 28% of the land in the United States, understanding both greenhouse gas emissions and sequestration on these lands is essential to informing land management practices that can mitigate greenhouse gas emissions.
