EPA underestimated methane emissions including those from gas leaks

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...

EPA seen underreporting emissions: what that means for natural gas use
2014-02-14 18:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Monitor: For years, natural gas has enjoyed a reputation as the cleanest fossil fuel because it releases less carbon dioxide into the atmosphere when it is burned than coal or oil. With technology that allows companies to extract gas from reservoirs trapped in underground shale deposits in the US, domestic gas has become plentiful and cheap. As a result, it is increasingly replacing coal in power generation, and is substituting for gasoline and diesel fuel in fleets of retrofitted vehicles. But from...
EPA Vastly Misjudges Methane Leaks, Study Confirms
2014-02-13 20:04:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The federal government has underestimated methane emissions from the United States by 50 percent for the past 20 years, according to a comprehensive new study. Methane, also called natural gas, is a powerful but short-lived greenhouse gas. It lasts just nine years in Earth's atmosphere but is about 34 times more potent at trapping infrared radiation (the greenhouse effect) than carbon dioxide, which is more abundant and lasts longer. While methane spews into the sky from both natural sources,...

Maine businesses support EPA power plant rules

Associated Press: Hundreds of Maine businesses are calling on U.S. Sens. Susan Collins and Angus King to support new standards proposed by the Environmental Protection Agency for power plants. Several business leaders are holding a news conference Wednesday in Portland in support of the proposed rules that would impose tough requirements on new coal-fired power plants, setting the first-ever limits on carbon dioxide and other pollutants blamed for global warming. Bonnie Frye Hemphill of the Natural Resources Council...
