TL;DR: It is found that a shift to compressed natural gas vehicles from gasoline or diesel vehicles leads to greater radiative forcing of the climate for 80 or 280 yr, respectively, before beginning to produce benefits.

TL;DR: The magnitude of this leakage was reassessed and it was found that in 2015, supply chain emissions were ∼60% higher than the U.S. Environmental Protection Agency inventory estimate, likely because existing inventory methods miss emissions released during abnormal operating conditions.

TL;DR: This work reconciles top-down and bottom-up methane emissions estimates in one of the country’s major natural gas production basins using easily replicable measurement and data integration techniques and reduces uncertainty in top- down estimates by using repeated mass balance measurements, as well as ethane as a fingerprint for source attribution.

TL;DR: A high-resolution satellite data–based atmospheric inversion framework is demonstrated, providing a robust top-down analytical tool for quantifying and evaluating subregional methane emissions from the Permian Basin.

TL;DR: This inventory's higher O&G emission estimate was due primarily to its more comprehensive activity factors and inclusion of emissions from fat-tail sites, which was higher than alternative inventories based on the United States Environmental Protection Agency (EPA) Greenhouse Gas Inventory, EPA Greenhouse gas Reporting Program, and Emissions Database for Global Atmospheric Research by factors of 1.5, 2.7, and 4.3.
