The agency converts the methane emissions into their equivalent in carbon dioxide, following standard scientific practice.
That company creates ethanol from landfill trash that, in turn, reduces methane emissions that contribute to global warming.
Moreover, although controversial, life-cycle analysis indicates that fugitive methane emissions make shale gas obtained by hydraulic fracturing as carbon-intensive as coal.
FORBES: Carbon Tax: Will Tweedle Dum Snatch Defeat From the Jaws of Victory?
By eliminating venting, methane emissions can be kept to an acceptable minimum.
ECONOMIST: The ��golden age of gas�� could be cleaner than greens think
The new EPA figures still show natural gas operations as the leading source of methane emissions in the U.S., at about 145 million metric tons in 2011.
You got it, stop unconventional productions of natural gas from shales because unconventional natural gas from shales is the single most prevalent present source of methane emissions.
Other observers have written that the focus on carbon dioxide above all else has been misplaced, since quick wins are available in other areas like cutting methane emissions or black carbon soot.
ECONOMIST: Leaked e-mails do not show climate scientists at their best
The agency highlighted the rise in methane emissions, which it says is probably due to higher than average emissions from wetlands around the Arctic and in the tropics, both related to weather conditions.
When I talked to Krupp a day after the panel he said one of the big challenges was just measuring methane emissions from fracking and determining the break-even point where any fugitive emissions would not exceed the carbon savings from replacing coal.
In a mid-April report on greenhouse emissions, the agency now says that tighter pollution controls instituted by the industry resulted in an average annual decrease of 41.6 million metric tons of methane emissions from 1990 through 2010, or more than 850 million metric tons overall.
Ingraffea and Dr. Howarth authored a study on methane emissions a couple of years ago that was thoroughly debunked within about 30 minutes of its issuance, yet their absurd findings continue to be parrotted by the anti-fracking movement and an often incurious news media as if they were unchallenged fact.
Methane and carbon emissions combined are less than those emanating from landfills.
The oil and gas industry has said the EPA has overestimated emissions of methane and argued that they already were working to reduce pollution, without the agency's intervention.
The coalition is a U.S.-led effort to combat emissions of black carbon, methane, and hydrofluorocarbons (HFCs).
FORBES: Researchers Argue For Action On Short-Lived Climate Pollutants
Siemens and Shell, for example, have just announced a new fuel-cell technology for oil rigs that will capture emissions of carbon dioxide and methane, generate power from them cleanly, and sequester the exhaust.
