October 17, 2025: Plaintiffs File Reply Brief

The youth plaintiffs filed their reply brief to the Alaska Supreme Court, responding to the State’s brief on appeal. The plaintiffs argue that it is squarely within the authority of Alaska’s courts to determine whether the state laws mandating development of the Alaska LNG Project violate Alaska’s Constitution.  

They emphasized that their case does not ask Alaska’s courts to solve climate change, but to prevent the massive, long-term pollution and constitutional harms the project would cause to their lives, health, and cultural traditions. The plaintiffs explained that their case is fundamentally different from previous Alaska climate cases, Kanuk and Sagoonick I, which involved different conduct and remedies, and that the Court’s decisions in those cases confirm that their case is justiciable.  

They also asserted that the State’s arguments mischaracterize their claims, exceed the scope of appeal, and that their allegations—taken as true—sufficiently show the project’s statutory mandate cannot be fulfilled without causing unconstitutional climate harms.
