Frack-happy Colorado clamps down on methane pollution

2014-02-25 21:42:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: Frackers and other companies that handle natural gas will have to start being at least a little bit neighborly in Colorado, where new rules will force them to clamp down on methane leaks from wells, tanks, and pipelines. When methane (natural gas is pretty much just methane) escapes during drilling and transportation, it fuels ozone pollution and global warming. Methane concentrations in the atmosphere are rising, and methane leaks are a major problem in the U.S. By one recent estimate, the U.S....

Methane, friend and foe for climate change

2014-02-17 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Washington Post: A STUDY in the journal Science finds that the United States is putting a lot more methane, a potent contributor to global warming and the primary compound in natural gas, into the air than the Environmental Protection Agency (EPA) has estimated. But the report also shows that the problem is fixable -- and not a reason to shut down the controversial extraction method known as fracking. Natural gas, as a transitional fuel, remains an important response to climate change. Methane is a powerful driver...

EPA underestimated methane emissions including those from gas leaks

2014-02-15 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ClimateWire: In recent years, as the natural gas boom has led to the fuel playing an increasing role in the U.S. energy mix, a debate has been raging over its climate benefits. A number of studies measuring emissions of methane, a key component of natural gas with 30 times the warming potential of CO2, have measured significant leakages of the gas. If such leaks are common, the climate benefits of burning natural gas rather than coal diminish. Drilling for natural gas (methane) in coal country can be...

America's natural gas system is leaking methane & in need of a fix

2014-02-14 20:17:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, as well as those from the natural gas industry specifically. Natural gas consists predominantly of methane. Even small leaks from the natural gas system are important because methane is a potent greenhouse gas -- about 30 times more potent than carbon dioxide. A study, "Methane Leakage from...

Methane leaks far higher than US estimates

2014-02-14 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

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,...
