I’ve written before on this topic, and wanted to present the latest peer-reviewed response to the Howarth paper from 2011 that caused quite a stir:

    The GREET guys just took a crack at this as well. I don’t have the article in front of me, but I believe they found that conventional NG had a worse footprint than expected, that shale gas was on par with conventional, and that both offered better GHG performance than coal for most of the energy end uses and analytic time frames considered. It’s often confusing to distinguish where the differences in different LCA studies come from- either from different raw emission factor data sources, or from different analytical assumptions. The best studies will make that very explicit, and offer validation against past studies and/or sensitivity analysis for the different inputs and assumptions.
