交通运输部门的脱碳对限制全球变暖至关重要，但由于成本承担方的普遍反对，面临着严峻的政治可行性挑战。对于在交通运输排放中占最大份额的私人机动车，各种研究表明，对电动汽车（ev）和充电基础设施的补贴等拉动措施比碳税或逐步淘汰化石燃料汽车的监管等推动措施更能吸引公众的支持。基于瑞士大量代表性样本（N = 5325）的选择实验，我们重新评估并补充了这些发现。根据经验，我们之所以关注瑞士，是因为瑞士新注册的汽车在欧洲的排放记录最糟糕。首先，我们通过揭示为这些政策措施提供资金的手段方面的成本影响，研究这种支持是否受到（负面）影响，重新评估对拉动措施的可能更强的支持。其次，我们研究的一个独特之处在于，我们考察了非电动汽车和电动汽车车主对促进电动汽车的政策支持。我们的假设是，即使成本影响变得明显，电动汽车持有者也可能更支持此类政策。我们的主要发现是，即使政策资助被披露，对拉动措施的支持在非电动汽车持有者中很高，在技术采纳者（电动汽车持有者）中甚至更高。这表明，在这一领域，更雄心勃勃的拉动措施在政治上是可行的，尤其是随着电动汽车采用者比例的增加。我们的研究也为其他国家的类似研究提供了方法模板。
Decarbonizing the transportation sector is crucial to limiting global warming, but faces severe political feasibility challenges due to widespread opposition by those who incur the costs. With respect to private motorized vehicles, which account for the largest share of emissions from transportation, various studies show that pull measures, such as subsidies for electric vehicles (EVs) and charging infrastructure, attract more public support than push measures, such as carbon taxes or regulation to phase out fossil fuel cars. Based on a choice experiment with a large, representative sample (N = 5325) of car holders in Switzerland, we reassess and add to these findings. We empirically focus on Switzerland because its newly registered cars have the worst emissions record in Europe. First, we reassess the presumably stronger support for pull measures by studying whether such support is (negatively) affected by revealing the cost implications in terms of means for funding these policy measures. Second, a unique feature of our study is that we examine support for policies to promote EVs both amongst non-EV and EV holders. Our hypothesis is that EV holders are likely to be more supportive of such policies, even when cost implications become apparent. Our key finding is that support for pull measures, which is high amongst non-EV holders, and even higher among technology adopters (EV holders), remains stable even when policy funding is revealed. This suggests that more ambitious pull measures in this area are politically feasible, even more so as the share of EV-adopters increases. Our research also provides a methodological template for similar research in other countries.
