Abstract
This paper examines the relationship between environmental accidents and voting. Following the 1986 Chernobyl disaster, environmentalist parties entered parliaments in several nations. This paper uses Chernobyl as a natural experiment creating variation in radioactive fallout exposure over Sweden. I match municipality-level data on cesium ground contamination with election results for the environmentalist Green Party, which was elected to parliament in 1988. After adjusting for pre-Chernobyl views on nuclear power, the results show that voters in high-fallout areas were more likely to vote for the Greens. Detailed individual-level survey data suggests that resistance to nuclear energy increased in fallout-effected areas after the accident, and that this change was driven by voters who followed local media closely.
