Shale Gas and Greenhouse Gas Footprint

Last summer, we reported on an article by a group of Cornell University professors (led by Robert Howarth) that concluded that shale gas has a higher greenhouse gas (GHG) footprint than coal. Recently, a study also from Cornell concludes that the earlier Cornell study by Howarth was “seriously flawed,” and that shale gas has a GHG footprint that is almost half that of coal.

The debate continues. Read the recent Cornell commentary here.
