A group of youth activists is asking a federal court to block the EPA's repeal of the climate endangerment finding. They argue that allowing the repeal to stand during litigation could lead to nearly one billion metric tons of additional carbon dioxide emissions from less efficient vehicles. While environmental groups and several states are also challenging the rule, they have not yet joined the request for an immediate stay. The legal move could potentially trigger early Supreme Court involvement, creating a high stakes battle over federal emissions standards.
