Public Health Theses

Abstract

Background & Aims: Fossil fuel combustion emits a spectrum of ambient air pollutants, with the most harmful health effects seen from particulate matter 2.5 μm or less in diameter (PM2.5). Pricing carbon can reduce PM2.5 emissions and yield co-benefits for public health. The Regional Greenhouse Gas Initiative (RGGI) is a cooperative carbon pricing initiative among twelve states aiming to curb carbon dioxide emissions from the power sector. This preliminary analysis explores methodological approaches to quantify the health benefits associated with PM2.5 changes after RGGI was first implemented in 2009.

Methods: An interrupted time series analysis was performed to compare …
