US pollution rollbacks threaten reproductive health. The EPA’s revocation of the endangerment finding for greenhouse gases removes a legal lever crucial to controlling emissions from transport and power generation. The policy shift will degrade air quality and intensify climate hazards, heat, wildfire smoke, storms, with disproportionate effects on pregnant people and newborns.

Evidence links extreme heat and air pollutants to adverse birth outcomes; communities of colour and low-income groups bear the brunt.

Dismantling environmental protections is not abstract policymaking, it is a direct challenge to reproductive and public-health rights. Policymakers must recognize climate regulation as reproductive justice infrastructure, restore scientific assessments, and protect the most exposed communities through targeted mitigation and adaptation measures.
