Travel behaviour and greenhouse gas impacts of income-conditioned e-bike purchase incentives
研究了加拿大萨尼奇市基于家庭收入的电动自行车购买补贴对出行行为和温室气体排放的影响，发现补贴促使高收入群体减少更多汽车出行，减排成本具有竞争力。
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.
