Supreme Court blocks rule, worsening air pollution for downwind states

A recent Supreme Court ruling has blocked the EPA's "Good Neighbor Plan," which aimed to regulate interstate air pollution, exacerbating the burden on downwind states. Air pollution is linked to 7-9 million deaths annually, including 200,000 in the U.S. Researchers highlight challenges faced by downwind states in petitioning the EPA for regulation, noting lengthy processes and insufficient data access hinder effective action against pollution.
