The Demand for Global and Local Environmental Protection: Experimental Evidence from Climate Change Mitigation in Beijing
通过北京居民购买碳排放交易许可的实验，发现自愿减缓气候变化的需求很大程度上受当地空气污染等本地协同效益驱动。
In this study, participants from Beijing, China, were offered the opportunity to contribute to voluntary climate change mitigation by purchasing permits from two Chinese CO<sub>2</sub> emissions trading schemes (ETS). Since CO<sub>2</sub> emissions abatement is linked to other local benefits like the reduction in emissions of air pollutants, our aim is to separate the demand for local and global environmental protection. To this end, Beijing and Shenzhen ETS permits were offered. Our results indicate that a substantial part of the revealed demand for voluntary climate change mitigation in Beijing is driven by concerns for local co-benefits of CO<sub>2</sub> emissions reduction.
