The Constitution gives States standing, and the Supreme Court original jurisdiction.

But in practice if the court doesn't issue a writ of certiorari the cases are filtered through the circuit courts which sometimes rule lack of standing see Mass vs EPA. The Supreme Court ruled by 5-4 that Massachusetts did have standing to sue. (Roberts, Alito, Scalia and Thomas voted against standing). That is why I'm in favor of a tactic making the suit go the opposite direction.
