Major Study Projects No Long-Term Climate Benefit from Shale Gas Revolution

More abundant, cheaper shale gas (dark blue) has little impact on annual growth in U.S. CO2 emissions through 2050 compared to low shale gas case (light blue). This is true for multiple energy-economy models. Deep cuts in CO2 require a rising carbon price (green). (Credit: Energy Modeling Forum, Stanford University) Click to enlarge.
Most claims that shale gas will significantly reduce US carbon emissions in the future are based on little more than hand-waving and wishful thinking.  That’s because those claims assume natural gas is replacing coal only, rather than replacing some combination of coal, renewables, nuclear power, and energy efficiency — which is obviously what will happen in the real world.

To figure out what the impact of shale gas is actually going to be, you need an energy-economy model.  And since the output of one model depends crucially on the specific assumptions it makes, the best approach would be to look at results of several models. And that is precisely what Stanford’s Energy Modeling Forum does in its new study, “Changing the Game? Emissions and Market Implications of New Natural Gas Supplies Report.”
