Methane leaks far higher than US estimates

Agence France-Presse: The natural gas system in the United States is leaking far more methane, a harmful greenhouse gas, into the air than official estimates say, according to research released Thursday. The report by researchers at seven major universities reviewed some 200 studies from the past two decades and found that the Environmental Protection Agency is missing leakage from various sources in North America, including faulty pipelines, wetlands, natural seepage from the Earth's crust and other sources. However,...

Underestimated Methane Leaks Make Natural Gas Dirtier Than Previously Thought, Says Study
2014-02-14 00:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Forbes: Methane emissions are worse than the conventional wisdom would have you believe, according to a new study by researchers at Stanford University. Methane, which is the primary component of natural gas, is an especially powerful greenhouse gas, packing more than two dozen times as much global warming potential than carbon dioxide. Traditionally, environmental regulators and energy industry groups have estimated methane emissions by multiplying the amount of methane emitted by a specific source...

Natural Gas May Benefit Climate Despite Methane Leaks
2014-02-13 22:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Methane leaks are common in the U.S. natural gas production and distribution system, but they do not fully negate the climate benefits of using natural gas to produce electricity over burning coal for electric power, according to a new Stanford University analysis. The paper, to be published Friday in the journal Science, concludes that U.S. Environmental Protection Agency inventories underestimate methane emissions from natural gas production, but hydraulic fracturing -- a process of fracturing...
