Doctoral Seminar

Abstract: We use a new indicator of environmental legislation to study the evolution in intensity of legislative provisions in environmental policy. Our study covers developed and developing economies (138 countries) over half a century (1970-2020). We investigate the main determinants of trends in environmental legislation, among which extreme climate events. In particular, we examine whether the frequency of natural disasters - droughts, floods, storms, extreme temperatures, wildfires - influences environmental policy stringency. We find that countries are more likely to adopt more stringent environmental laws and regulations if there are more frequently hit by droughts and extreme temperatures, but less likely if they are more frequently hit by floods. Legislative measures differ markedly depending on regional groups of countries, types of disasters and environmental areas.
