Researchers say fuel market rebound effect can result in increased GHG emissions under RFS2; suggest taxes over mandates

Green Car Congress

This “fuel market rebound effect” can undermine climate change mitigation strategies, even to the point where efforts to reduce GHG emissions by increasing the supply of low-carbon fuels may actually result in increased GHG emissions. gallons, selected a conservative gasoline displacement rate of 0.50 for its analysis.
