Offshoring Emissions Through Used Vehicle Exports
In this peer-reviewed study, the authors estimate the emissions-shifting impact of used vehicle exports from Great Britain between 2005 and 2021. They conclude that exported vehicles generate significantly more CO2 per kilometer.Read More →
Geostationary Satellite Observations of Extreme and Transient Methane Emissions from Oil and Gas Infrastructure
In this peer-reviewed study, the authors use continuous 5-minute monitoring of large methane point sources with geostationary satellites to document and quantify large methane releases from oil and gas infrastructure.Read More →
A measurement-based upstream oil and gas methane inventory for Alberta, Canada reveals higher emissions and different sources than official estimates
This peer-reviewed study presents a methane inventory for conventional upstream oil and gas operations in Alberta, Canada, and finds that asset-level methane emissions are approximately 1.5x the federally reported levels.Read More →
Constraining Sector-Specific CO2 Fluxes Using Space-Based XCO2 Observations Over the Los Angeles Basin
This peer-reviewed study uses NASA's Orbiting Carbon Observatory to study sector-specific CO2 emissions in the Los Angeles Basin between January 2020 and December 2021.Read More →
Mapping methane reduction potential of tidal wetland restoration in the United States
This peer-reviewed study provides a new assessment of coastal methane reduction opportunities in the U.S., and identifies a map of 1,796 parcels with the potential for tidal reconnection that can reduce methane emissions from coastal wetlands.Read More →
Excess methane emissions from shallow water platforms elevate the carbon intensity of US Gulf of Mexico oil and gas production
This peer-reviewed study presents an approach to calculating the carbon intensity of oil and gas production in the Gulf of Mexico, finding that government inventories underestimate the amount of methane produced by these operations.Read More →
Black carbon aerosols over Indian Ocean have unique source fingerprint and optical characteristics during monsoon season
This peer-reviewed study examines black carbon aerosols over the Indian ocean during the less-studied monsoon season, finding that savanna-burning fires from Africa periodically account for half of BC loadings over the Indian Ocean.Read More →
Wetland emission and atmospheric sink changes explain methane growth in 2020
In 2020, atmospheric methane growth reached record levels despite a likely decrease in anthropogenic methane emissions due to the COVID-19 pandemic. This study quantifies 2020 methane emissions sources.Read More →
Atmospheric observations suggest methane emissions in north-eastern China growing with natural gas use
Using atmospheric and satellite observations of methane, this study estimates poorly-measured methane emissions in China, and concludes that China's increased methane emissions are largely attributable to the growth in China's natural gas use.Read More →
