An Act to ensure cleaner air for communities overburdened by outdoor air pollution

This bill requires Massachusetts to address air pollution in communities disproportionately affected by outdoor air pollution. It creates a technical advisory committee to identify pollution "hotspots" near highways, industrial areas, and transportation hubs, and mandates new air monitoring for pollutants like black carbon and ultrafine particles. By 2030, the state must reduce pollution levels in these hotspots by 50% compared to 2026 baselines, with a 75% reduction target by 2035. The bill also requires high-efficiency air filtration systems in specific buildings within 200 meters of pollution sources - including public housing, schools, colleges, and large commercial buildings - to improve indoor air quality for residents and workers.
