The effects of RGGI on mortality outcomes
(Montana State University - Bozeman, College of Agriculture, 2024) Power, Nicholas Markert; Chairperson, Graduate Committee: Justin Gallagher
Most debates around market-based solutions to reduce greenhouse gas emissions often focus on greenhouse gas emissions reductions and cost-effectiveness. The Regional Greenhouse Gas Initiative (RGGI) is a cap-and-trade program designed to curb greenhouse gas emissions, and was implemented in 2009 across nine states in the greater New England area. The World Health Organization (WHO) states that over 6.5 million people die from air pollution annually. Particulate Matter of 2.5 microns or less in diameter is a major component in greenhouse gas emissions and has a myriad of deleterious effects to human health. This paper explores whether the RGGI policy had an impact on mortality rates, using a difference-in-differences approach, and estimates reduction in Cardiovascular related mortalities for the age cohort 15-64. I estimate that there are approximately 12 fewer deaths per county effected by the RGGI policy from 2009- 2019.Combined with the 45 counties affected by the policy, there are an estimated 553 fewer cardiovascular related mortalities for the 15-64 age group from 2009-2019 as compared to the counties unaffected by the policy. Robustness checks are run to verify the reliability of this finding.
