The Environmental Health Restoration Act of 2026 would reverse deregulatory actions taken by the EPA since January 2025 and restore environmental protections that the bill claims were weakened or eliminated. Specifically, the bill requires the EPA to reinstate regulations within 60 days governing greenhouse gas emissions from power plants and vehicles, methane pollution from oil and gas operations, mercury and air toxics standards, and air quality standards for fine particulate matter. The legislation also prohibits the EPA from further delaying, suspending, or weakening these regulations without explicit congressional approval. Additionally, the bill mandates that the EPA restore scientific advisory committees, base regulatory decisions on peer-reviewed science, reinstate the use of social cost of carbon calculations in environmental decisions, and restore environmental justice programs focused on communities experiencing disproportionate pollution. The bill authorizes approximately $11 billion annually for EPA enforcement activities and requires annual reports to Congress on enforcement actions, while also allowing individuals to sue the EPA for non-compliance with the law.
