The uptake of actions to mitigate climate change at the household level might crowd out subsequent policy at the national level, which is problematic because national policy often has a larger mitigation potential than individual household measures. This study analyses crowding out between the uptake of low-cost actions and the support for national climate change policy in the agricultural sector. In the experimental set-up, survey respondents were primed to think about the implementation of low-cost mitigation practices and subsequently asked to express support for national mitigation policy. The results show a crowding-out effect between individual mitigation measures and support for national policy. Individuals with high levels of worry show a stronger crowding out effect. This study contributes to building understanding of when and why crowding out occurs in order to help frame and communicate future climate change policy.

在家庭层面采取减缓气候变化的行动可能会排挤国家层面的后续政策，这是有问题的，因为国家政策通常比单个家庭措施具有更大的减缓潜力。本研究分析了低成本行动的采用与农业部门对国家气候变化政策的支持之间的挤出。在实验设置中，调查受访者准备考虑实施低成本缓解措施，随后要求表达对国家缓解政策的支持。结果表明，个别缓解措施与对国家政策的支持之间存在挤出效应。焦虑程度高的个体表现出更强的挤出效应。
