EDF’s analysis indicates that methane emissions from gas pipeline leaks are significantly higher than current estimates by the U.S. Environmental Protection Agency’s Greenhouse Gas Inventory. This report details policy recommendations to reduce leakage from pipelines and EDF's methodology for estimating methane emissions from pipeline infrastructure.

Higher temperatures in socially vulnerable US communities increasingly limit safe use of electric fans for cooling
Type: Column/Article
Date: August 10, 2023
This study from EDF scientists and partners uses hourly weather reanalysis data (1950–2021) to examine the temporal and spatial evolution of ambient climate conditions in the continental United States considered safe for fan use, focusing on high social vulnerability index regions. Authors find that some regions experience hundreds to thousands of hours per year that are too hot for safe fan use.

Preventing and mitigating hydrogen emissions from infrastructure
Type: Fact Sheet
Date: August 8, 2023
Maximizing hydrogen’s decarbonization benefits requires minimizing hydrogen emissions throughout the value chain. Hydrogen is a leak-prone gas that can indirectly warm the climate. While preventing and mitigating hydrogen emissions involves identifying/quantifying emissions from infrastructure, there are actions that can be taken now to help reduce future emissions.

With the help of new hydrogen measurement technology and experts in making trace gas measurements, EDF is launching the Hydrogen Emissions Measurement Study.
-
Hydrogen is a tiny, leak-prone molecule that can indirectly warm the climate. Thus, hydrogen emissions from its value chain could considerably undermine the anticipated climate benefits of a hydrogen economy. This EDF review paper synthesizes studies to provide an overview of the available knowledge on hydrogen emissions across value chains.

An audit on the Advanced Clean Fleets Rule is bad for California and bad for the country
Type: Column/Article
Date: June 29, 2023
Last month, the California Air Resources Board unanimously voted to adopt the Advanced Clean Fleets Rule, which sets purchase requirements for private and government fleets to increasingly transition to zero-emission trucks, and sets a 100% sales requirement for manufacturers in 2036.
