Long before Congress, a notoriously conservative Court started taking pollution seriously.
Well over a century ago, the Supreme Court ruled that it had that power to remedy interstate water pollution. That was in 1901. Six years later, the Court decided its first air pollution case.

A sleeper Supreme Court case could impact state climate legislation.
A month from now, the Supreme Court will hear a case about an animal cruelty law. It’s not an environmental law case, but the ruling could impact the authority of states to address climate change.
