Paradoxically, there could even be more emissions as a result of some improvements in energy efficiency, these economists say.Would you spend the money you saved by having a fuel efficient car by buying a carbon intensive trip to Hawaii?

The problem is known as the energy rebound effect. While there’s no doubt that fuel-efficient cars burn less gasoline per mile, the lower cost at the pump tends to encourage extra driving. There’s also an indirect rebound effect as drivers use the money they save on gasoline to buy other things that produce greenhouse emissions, like new electronic gadgets or vacation trips on fuel-burning planes.
