Juliana, et al. v. United States of America, et al. is a climate-related lawsuit filed in 2015 by 21 youth plaintiffs against the United States and several executive branch officials. Filing their case in the United States District Court for the District of Oregon, the plaintiffs, represented by the non-profit organization Our Children's Trust, include Xiuhtezcatl Martinez, the members of Martinez's organization Earth Guardians, and climatologist James Hansen as a "guardian for future generations". Some fossil fuel and industry groups intervened as defendants, but were later dropped at their request following the 2016 presidential election.
