Indoor Air Quality and Healthy Schools Act of 2025

This bill requires the EPA to establish guidelines for indoor air contaminants like radon, formaldehyde, and carbon monoxide that affect schools and childcare facilities. It mandates a national assessment of indoor air quality in these buildings, with updates every five years, and provides technical assistance to schools and childcare providers to implement air quality improvements. The EPA must publish science-based guidelines with recommended concentration limits for key contaminants and support voluntary building certifications for healthier indoor environments. These provisions directly impact local schools, childcare centers, and state/local governments responsible for building maintenance and health standards.
