Guest Post: Shale Gas - The Low Carbon Option?

It may be surprising to hear that hydraulic fracturing is not the cause of water contamination , but what may be even more surprising is that shale gas produced using fracking may have lower life cycle greenhouse gas emissions than conventional gas.According to a recent Environmental Science and Technology report, “shale gas life-cycle [greenhouse gas] emissions are 6% lower than conventional natural gas”There are several reasons why shale gas could have lower greenhouse gas (GHG) emissions, but perhaps the most significant reason is that multiple horizontal wells (used when tapping shale gas) can be drilled from a single well pad...
