Market-Based Policies for Green Motoring in Canada.

The most effective policy to address environmental externalities from vehicular fuel use is an appropriate fuel tax. Instead of raising fuel taxes, Canada's provincial and federal governments prefer to subsidize the purchase of fuel-efficient vehicles and the accelerated retirement of old vehicles. Are these programs effective? Can they be improved? We argue that subsidies for hybrids and electric vehicles are not cost-effective and instead recommend building on Canada's brief and modest experience with 'feebates.' While British Columbia's pioneering accelerated vehicle retirement program is cost-effective, its success rests significantly on inducing participants to switch from personal vehicles to alternative transportation modes. Policy refinements will be needed to adapt the lessons learnt from this program to less favourable conditions elsewhere in Canada. [ABSTRACT FROM AUTHOR]
