Natural gas from fracking could be 'dirtier' than coal,
Cornell professors find
The article includes a link (in red, below) to the full peer reviewed paper Howarth presented.
The study is the first peer-reviewed paper on methane emissions from shale gas, and one of the few exploring the greenhouse gas footprints of conventional gas drilling. Most studies have used EPA emission estimates from 1996, which were updated in November 2010 when it was determined that greenhouse gas emissions of various fuels are higher than previously believed.

Assembly Testimony by Cornell Geologist Dr. Robert Howarth - submitted Oct. 12, 2011.
"The draft sGEIS fails to use the most recent and best scientific information, and as a result, the document reaches many incorrect conclusions and fails to adequately protect the environment and people of New York State. As Prof. Tony Ingraffea and I wrote in an invited commentary for the journal Nature on September 15, 2011, “Because shale gas development is so new, scientific information on the environmental costs is scarce. Only this year have studies in peer-reviewed journals begun to appear, and these give reason for pause.” (Howarth & Ingraffea, Should fracking stop? Yes, it’s too high risk, Nature, v. 477, pages 271- 273).
