Methane and the Greenhouse-Gas Footprint of Natural Gas from Shale Formations
"The footprint for shale gas is greater than that for conventional gas or oil when viewed on any time horizon, but particularly so over 20
years. Compared to coal, the footprint of shale gas is at least 20% greater and perhaps more than twice as great on the 20-year horizon and is comparable when compared over 100 years." By Howarth, Santoro and Ingrafea. Climatic Change Letters, May 2011.

Greenhouse gases, climate change and the transition from coal to low-carbon electricity
Conservation, wind, solar, nuclear power, and possibly carbon capture and storage appear to be able to achieve substantial climate benefits in the second half of this century; however, natural gas cannot. BY N P Myhrvold and K Caldeira published in Environmental Research Letters February 16, 2012.

Comparative Life-Cycle Air Emissions of Coal, Domestic Natural Gas, LNG, and SNG for Electricity Generation
A 2007 study comparing greenhouse gas (GHG), SOx, and NOx life-cycle emissions of electricity generated with NG/LNG/SNG and coal.
The study shows that with the current fleet of power plants, a mix of domestic NG, LNG, and SNG would have lower greenhouse gas emissions than coal. But if advanced technologies with carbon capture and sequestration (CCS) are used, however, coal and a mix of domestic NG, LNG, and SNG would have very similar lifecycle greenhouse gas emissions. For SOx and NOx the study finds that there are significant emissions in the upstream stages of the NG/
LNG life-cycles, which contribute to a larger range in Sox and NOx emissions for NG/LNG than for coal and SNG.
