New study: U.S. power plant emissions down

CIRES, NOAA scientists find switch to natural gas power plants means fewer air pollutants

Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in the journal Earth’s Future, a journal of the American Geophysical Union. The so-called “combined cycle” natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality.

CIRES, NOAA observe significant methane leaks in a Utah natural gas field

On a perfect winter day in Utah’s Uintah County in 2012, CIRES scientists and NOAA colleagues tested out a new way to measure methane emissions from a natural gas production field. Their results, accepted for publication in Geophysical Research Letters, constitute a proof-of-concept that could help both researchers and regulators better determine how much of the greenhouse gas and other air pollutants leak from oil and gas fields. 

Scientists working to crack key air quality and climate mysteries in...

Scientists this summer are taking one of the most detailed looks ever at the natural and manmade emissions that affect air quality in the Southeast, and their movement and chemical transformations within the atmosphere. The mission should help scientists determine the origin of the fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends.

Mystery solved: "Extra” methane in LA's air traced to fossil-fuel sources

A new study, led by NOAA and its Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, used a novel approach to trace methane in the Los Angeles basin back to its sources, and found that "extra" methane is likely coming from sources related to fossil fuels.
