A study led by research team including Harvard TH Chan School of Public Health,  PSE Healthy Energy, Atmospheric and Environmental Research AER, Gas Safety Inc., Boston University, and Home Energy Efficiency Team (HEET) found that gas used in homes throughout the greater Boston area contains at least 21 different hazardous air pollutants that may impact air quality and health, wherever natural gas is leaked. The research, published in Environmental Science & Technology, is the first to test for health-damaging air pollutants in unburned natural gas when it is used in our homes.

Researchers collected over 200 unburned natural gas samples from 69 unique kitchen stoves and building pipelines across Greater Boston between December 2019 and May 2021.
