Study finds methane leaks from three large US natural gas fields in line with EPA estimates

Green Car Congress

We are beginning to get a sense of regional variation in methane emissions from natural gas production. The gas fields we studied for this paper produced about 20% of the natural gas in the United States, and more than half the shale gas, so this moves us closer to understanding methane leaks from US natural gas production.

Greyrock, Tsinhua U, DRI to assess potential of synthetic diesel to improve air quality in China

Green Car Congress

Greyrock Energy, a developer of a gas-to-liquids (GTL) process that produces synthetic diesel, will participate with Tsinghua University of Beijing, China and the Desert Research Institute (DRI) of Reno, Nevada to quantify the positive impact on air quality from the use of synthetic diesel fuels as compared with petroleum derived diesel fuels.

USGS/BOEM study identifies method to differentiate between natural seepage and produced oils in waters off Southern California

Green Car Congress

Resource managers now have a method to determine the source of oil found in the waters off Southern California and differentiate between naturally seeped oils and those produced by offshore oil and gas production. Other platform oils need to go through a more extensive biomarker analysis to distinguish them from natural seepage.

Study concludes that NG leakage higher than reflected in inventories; transportation fuel climate benefits questioned

Green Car Congress

A review of 20 years of technical literature on natural gas (NG) emissions in the United States and Canada comprising more than 200 papers has concluded that official inventories consistently underestimate actual CH 4 emissions due to leakage from the natural gas system.

Study finds that suburban sprawl cancels carbon-footprint savings of dense urban cores in US

Green Car Congress

Although population-dense cities contribute less greenhouse-gas emissions per person than other areas of the country, these cities’ extensive suburbs essentially wipe out the climate benefits, according to a new study by Christopher Jones and Daniel Kammen at UC Berkeley.
