Travel behaviour and greenhouse gas impacts of income-conditioned e-bike purchase incentives

Abstract

This study investigates the travel behaviour and greenhouse gas (GHG) impacts of an electric bicycle (e-bike) purchase incentive program in Saanich, British Columbia, Canada, which distributed purchase rebates in three tiers conditioned on household income. A panel of 402 study participants (including a control group) was surveyed in three waves. We find that 23 % to 76 % would not have purchased an e-bike without the rebate, increasing with rebate amount, and that the purchased e-bikes were used regularly. Larger, income-conditioned incentives were associated with higher pre-purchase automobile use and consequently greater post-purchase automobile travel reduction. The incentive recipients reduced their GHG from travel by an average of 16 kg CO 2 e per week one year after purchase, greater for the larger, income-conditioned incentives. The marginal and non-marginal GHG abatement costs were CA$722 and CA$190 per tonne CO 2 e, respectively, which is cost-competitive with other types of transportation subsidies, but not the international carbon market.
