Climate Central: Carbon dioxide emissions are causing the climate to change and those changes come with a real cost. The big questions are what's the price tag for that "social' cost and when does it gets paid? According the a new report, current best estimates could actually be on the low end thanks to "unknown unknowns.' The most recent estimate for the cost of a ton of carbon emissions -- referred to as the social cost of carbon -- is $37. That number was calculated in 2013 by 12 federal agencies using three...
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...

Underestimated Methane Leaks Make Natural Gas Dirtier Than Previously Thought, Says Study

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...
