NYC’s Clean Heat Initiative: A Case Study for Municipal Environmental Policy

By Micah Wood, Jane Sun, and Sihan Liu


New York City’s municipal government has implemented a series of local regulations designed to improve air quality across the city over the past two mayoral administrations. One such policy, the Clean Heat Initiative, curtailed the use of two heavy fuel oils used in building boilers for winter heating. Using publicly available data, we analyze whether the policy has been implemented as designed, and whether this implementation resulted in the intended outcome of meaningfully decreasing the concentration of dangerous PM2.5 particles in street-level air in neighborhoods across the city. This report includes an analysis of differentiated impacts in high and low income neighborhoods, and finds that a statistically significant relationship exists between the reduction in the total volume of No. 4 and No. 6 oils burned and the reduction of neighborhood level PM2.5 levels. We then offer suggestions for future regulation design to prioritize environmental justice and equity.
