Environmental outcomes of the US Renewable Fuel Standard
This article suggests that the carbon intensity of corn ethanol produced under the US Renewable Fuel Standard is no less than gasoline and likely at least 24% higher.Read More →
Bigger than Oil or Gas? Sizing Up Coal Mine Methane
This report finds that coal mining emits 52.3 million tonnes of methane per year, rivaling oil (39 million tonnes) and gas (45 million tonnes), and comparable to the climate impact of the CO2 emissions of all coal plants in China.Read More →
Global assessment of oil and gas methane ultra-emitters
This study finds that ultra-emitters constituted 8 to 12% (~8 million metric tons of methane per year) of the global oil and gas production methane emissions.Read More →
Global Methane Tracker 2022
The 2022 update of the IEA Global Methane Tracker provides a complete set of country-level estimates for methane emissions from the energy sector.Read More →
Methane and NOx Emissions from Natural Gas Stoves, Cooktops, and Ovens in Residential Homes
This study finds that annual methane emissions from all gas stoves in U.S. homes have a climate impact comparable to the annual carbon dioxide emissions of 500,000 cars.Read More →
Preliminary US Greenhouse Gas Emissions Estimates for 2021
This study estimates that United States' economy-wide GHG emissions increased 6.2% relative to 2020, though emissions remained 5% below 2019 levels.Read More →
Methane Emissions from Superemitting Coal Mines in Australia Quantified Using TROPOMI Satellite Observations
This study quantifies methane emissions from coal mines in Queensland, the largest coal-producing state in Australia.Read More →
Pre- and post-production processes along supply chains increasingly dominate GHG emissions from agri-food systems globally and in most countries
This study assesses greenhouse gas emissions from global and national agri-food systems.Read More →
Majority of US urban natural gas emissions unaccounted for in inventories
This study concludes that consumption-driven methane losses, such as in transmission or end-use, may be a large component of emissions that is missing from inventories.Read More →
Nationally determined contributions under the Paris Agreement: Revised synthesis report by the secretariat
This synthesis report updates the UNFCCC Secretariat's Sept. 2021 report, which had synthesized information from the 164 latest available nationally determined contributions communicated by the 191 Parties to the Paris Agreement.Read More →
