An improved understanding of public support is essential to design effective and feasible climate policies for aviation. Our motivation is the contrast between high support for air travel restrictions responding to the COVID-19 pandemic and low support for restrictions to combat climate change. Can the same factors explain individuals’ support for restrictive measures across two different problems?

Using a survey, we find that largely the same factors explain support. Support increases with expected effectiveness, perceived threat and imminence of the problem, shorter expected duration of the measure, knowledge, and trust, while support decreases with expected negative consequences for self and the poor. When controlling for all perceptions, there is no significant residual difference in support depending on whether the measures address climate change or COVID-19. The level of support differs because COVID-19 is perceived as a more imminent threat, and because measures are expected to be shorter-lasting and more effective.

更好地了解公众支持对于设计有效和可行的航空气候政策至关重要。我们的动机是对应对 COVID-19 大流行的航空旅行限制的高度支持与对应对气候变化的限制的低支持之间的对比。相同的因素能否解释个人对两个不同问题的限制措施的支持？

通过一项调查，我们发现大部分相同的因素可以解释支持。支持会随着预期的有效性、感知到的威胁和问题的紧迫性、措施的预期持续时间的缩短、知识和信任的增加而增加，而支持会随着预期对自己和穷人的负面后果而减少。在控制所有看法时，根据这些措施是针对气候变化还是针对 COVID-19，在支持方面没有显着的剩余差异。支持水平不同，因为 COVID-19 被视为更迫在眉睫的威胁，并且因为预计措施持续时间更短且更有效。
