Emissions: who emits, from which facilities, and the trend.
Atmospheric Chemistry and Physics (Copernicus Publications / EGU)26 Feb 2026
A team led by Luis Guanter reports on MethaneSAT's ability to locate individual high-emitting methane sources in oil and gas basins. The satellite operated from March 2024 to June 2025, measuring in the 1598-1683 nanometre band at 0.25 nanometre spectral…
Inside Climate News19 Mar 2026
Inside Climate News reports that Senator Sheldon Whitehouse, ranking member of the Senate Environment and Public Works Committee, opened an investigation in March 2026 into the gap between reported and observed methane pollution from the Permian Basin, the largest-producing US…
DeSmog (in partnership with the National Security Archive)18 Aug 2026
DeSmog, working with the National Security Archive, reports on industry lobbying against Subpart W, the methane element of the US Greenhouse Gas Reporting Program. The piece contrasts oil and gas companies publicly urging the EPA to preserve federal greenhouse gas…
International Energy Agency (IEA)04 May 2026
The IEA's Global Methane Tracker 2026 estimates that methane emissions from fossil fuel operations total 124 million tonnes a year, with oil the largest source at 45 Mt, coal at 43 Mt and natural gas at 36 Mt, plus roughly…
Geoscience Letters (Springer, Asia Oceania Geosciences Society)28 Apr 2026
Patra and colleagues examine why atmospheric nitrous oxide has been rising faster. Observations show growth accelerating to 1.15 parts per billion per year in 2019 to 2023, up from 0.68 in 2001 to 2005, with the strongest signal over tropical…

NOAA's Annual Greenhouse Gas Index measures the change in radiative forcing from long-lived greenhouse gases relative to 1990. For 2024 the index stood at 1.54, meaning effective radiative forcing from these gases was 54 percent greater than in 1990. Carbon…

Inside Climate News reports on an EPA rollback of hydrofluorocarbon restrictions announced in May 2026. The change extends by several years the timeline under which manufacturers of air conditioners and refrigeration equipment must scale back production of devices using high…
Carbon Brief03 Oct 2025
Carbon Brief's Q&A sets out what GWP* is and why it is disputed. GWP* weights short-lived gases such as methane by the change in their emission rate over time, rather than by the fixed multiplier used in the conventional 100-year…
Frontiers in Climate (Frontiers Media SA)18 Aug 2026
Klopatek and colleagues propose a method allowing livestock companies to report emissions using both GWP100, the metric required by existing corporate accounting standards, and GWP*, which evaluates how changing emission rates of short-lived pollutants affect global surface temperature over time.…
Earth System Science Data (Copernicus / Global Carbon Project)09 May 2025
The third edition of the Global Carbon Project's living review of the methane budget covers 2000 to 2020, combining top-down atmospheric inversions using in situ and GOSAT satellite observations with bottom-up process models and inventories. For 2010 to 2019, inversions…
