Methane emissions from the U.S. oil and natural gas supply chain were estimated using ground-based, facility-scale measurements and validated with aircraft observations in areas accounting for ~30% of U.S. gas production. When scaled up nationally, our facility-based estimate of 2015 supply chain emissions is 13 ± 2 Tg/y, equivalent to 2.3% of gross U.S. gas…

Incorporating Energy Efficiency-Driven Pollution Reductions into State Implementation Plans – Apr. 20

Energy efficiency is a valuable resource that achieves low-cost, multipollutant reductions in states across the country. However, while state air regulators can rely on energy efficiency to meet specific pollutant reductions required under the US Environmental Protection Agency’s (EPA’s) National Ambient Air Quality Standards (NAAQS), many states are missing out on this opportunity.

Pollution from power plants harms public health, contributing to heart attacks, respiratory conditions, asthma attacks, and premature death. Energy efficiency can benefit health by reducing power plant pollution. This report estimates the health and environmental benefits that would come from a nationwide 15% reduction in annual electric consumption. We present results nationally, for states, and…

The next energy frontier: Cutting fossil fuel use in buildings

, , , ,
“While the amount of pollution from burning fuel in homes and commercial buildings is a relatively small part of total emissions today — just 11% of U.S. energy-related emissions — it is a roadblock to reaching our 2050 climate targets, according to long-term climate mitigation analyses. Collaborative global initiatives can help individual countries to reduce…
