In its second-annual , the U.S. EPA has released 2011 data that shows that natural gas and oil production is the second-biggest source of U.S. greenhouse gas emissions. of greenhouse gas emissions from stationary sources
Methane emissions from drilling, including fracking, and leaks from transmission pipes totaled 225 million metric tons of carbon-dioxide equivalents in 2011, EPA said, second only to power plants, which emitted about 10 times that amount – over 2,200 million metric tons.
As I wrote here, industry leaders and the investment community alike say – and are demanding - that methane emissions from shale gas development must - and can - be addressed. In April of this year, the U.S. EPA issued new rules requiring capture of methane emissions from gas well completions by 2015 and flaring of methane from new gas wells in the interim.

EPA’s report makes clear the necessity of cleaning up natural gas’ methane act immediately – and tackling the much greater challenge of slashing emmisions from power plants. There is no more urgent work.
