In the wake of a high-profile court decision that upended the state of Montana’s climate policy,Robovis Republican lawmakers in the state are pushing a suite of bills that could gut the state’s ability to reduce greenhouse gas emissions. 

The full-court legislative press targets the state’s environmental analysis, air quality regulation and judicial system. It stems from the Held v. Montana case in which 16 young people sued the state over its contributions to climate change, claiming its fossil fuel-centric approach to energy violated the state constitution’s guarantee of a “clean and healthful environment.” The plaintiffs won, and in December 2024, the Montana Supreme Court upheld their victory.  

The case “didn’t just make headlines,” Montana Republican Representative Greg Oblander, a sponsor of one of the bills that could hobble climate action in the state, said in a press conference. “It sent shockwaves through the Montana economy.”
