Youth environmentalists bring Montana climate case to trial after 12 years, seeking to set precedent

HELENA, Mont. (AP) — Whether a constitutional right to a healthy, livable climate is protected by state law is at the center of a lawsuit going to trial Monday in Montana, where 16 young plaintiffs and their attorneys hope to set an important legal precedent.

It's the first trial of its kind in the U.S., and legal scholars around the world are following its potential addition to the small number of rulings that have established a government duty to protect citizens from climate change.

The trial comes shortly after the state's Republican-dominated Legislature passed measures favoring the fossil fuel industry by stifling local government efforts to encourage renewable energy while increasing the cost to challenge oil, gas and coal projects in court.

By enlisting plaintiffs ranging in age from 5 to 22, the environmental firm bringing the lawsuit is trying to highlight how young people are harmed by climate change now and will be further affected in the future. Their testimony will detail how wildfire smoke, heat and drought have harmed residents' physical and mental health.

Young plaintiffs who are challenging the constitutionality of a Montana policy that does not require state agencies to consider the effect of greenhouse gas emissions in issuing permits for fossil fuel development, argue climate change has made wildfire seasons more challenging, increasing the amount of smoke people inhale.

The plaintiffs' youth has little direct bearing on the legal issues, and experts say the case likely won't lead to immediate policy changes in fossil fuel-friendly Montana.

But over two weeks of testimony, attorneys for the plaintiffs plan to call out state officials for pursuing oil, gas and coal development in hopes of sending a powerful message to other states.

Plaintiff Grace Gibson-Snyder, 19, said she's felt the impacts of the heating planet acutely as wildfires regularly shroud her hometown of Missoula in dangerous smoke and as water levels drop in area rivers.

“We’ve seen repeatedly over the last few years what the Montana state Legislature is choosing,” Gibson-Snyder said. “They are choosing fossil fuel development. They are choosing corporations over the needs of their citizens.”

In high school, Gibson-Snyder was an environmental activist who was too young to vote when she signed on as a plaintiff. The other young plaintiffs include members of Native American tribes, a ranching family dependent on reliable water supplies and people with health conditions, such as asthma, that put them at increased risk during wildfires.

Some plaintiffs and experts will point to farmers whose margins have been squeezed by drought and extreme weather events like last year’s destructive floods in Yellowstone National Park as further evidence that residents have been denied the clean environment guaranteed under Montana’s Constitution.
