The political economy of environmental legislation: evidence from the British Parliament

This study investigates how local air quality influences UK Parliament members’ votes on environmental and climate change legislation. Using micro-spatial information at the 1 km-by-1 km grid level, I link local air quality to members of UK parliament (MPs') voting records from 2009 to 2019. I find compelling evidence that MPs representing highly polluted areas are more likely to vote against stringent environmental legislation. I also provide evidence that local political economy considerations constrain pro-environmental voting behaviour: industrialization exacerbates the negative relationship between pollution and pro-environmental voting behaviour by further discouraging MPs representing industrial areas from supporting stringent environmental legislations. These findings underscore the public choice trade-offs between enacting stringent climate change policies and preserving local industry and jobs.
