Montana’s top court upholds landmark ruling in youth climate case over greenhouse gas emissions

By The Associated Press

HELENA, Mont. (AP) — Montana’s Supreme Court on Wednesday upheld a landmark climate ruling that said the state was violating residents’ constitutional right to a clean environment by permitting oil, gas and coal projects without regard for global warming.

The justices, in a 6-1 ruling, upheld an August 2023 decision by a state judge that was considered a breakthrough in attempts by young environmentalists and their attorneys to use the courts to leverage action on climate change.

The justices found a policy that prevented Montana from considering the effect of greenhouse gases when issuing permits for fossil fuel development is unconstitutional.
