Youth Climate Activists Sue Wisconsin Over Fossil Fuel Policies

On August 23, 2025, a group of 15 young climate advocates, aged 8 to 17, filed a lawsuit against the state of Wisconsin over its pro-fossil fuel policies. The plaintiffs, led by 17-year-old Kaarina, argue that the state's laws governing the public service commission are hindering the transition to clean energy and violating their constitutional rights.

The lawsuit specifically targets two Wisconsin laws that prohibit the regulator from considering air pollution and require it to approve new fossil fuel power plants. The plaintiffs contend that these policies are preventing the state from meeting its own goal of 100% carbon-free electricity by 2050. They also claim that the perpetuation of an oil and gas-based electricity sector is harming their health, homes, and safety, thereby infringing on their rights to life, liberty, and the pursuit of happiness.

The case builds on previous wins by the non-profit law firms representing the young activists. In 2023, a Montana court ruled that the state's pro-fossil fuel policies violated the rights of young challengers, and a Wisconsin case concerning public records law was also successful. The plaintiffs in the new lawsuit hope to have the two Wisconsin laws declared unconstitutional, which could lead to their overturning.

The climate impacts on Wisconsin, including increased flooding, extreme weather, and ecosystem degradation, have already taken a toll on the young plaintiffs. Kaarina, who was forced to relocate her family due to a boulder rolling into her backyard, says the "incredibly traumatic and life-changing experience" inspired her to join the lawsuit. The plaintiffs are now asking the court to uphold their right to a livable future.
