SustainUS
SustainUS is a non-profit, nonpartisan, youth-led advocacy group in the United States. Its goal is to improve youth participation and youth empowerment as it relates to advancing sustainable development. SustainUS works particularly with youth and young people aged 13–29 and on United Nations conferences related to youth and/or sustainability.
SustainUS has helped to create youth coalitions in the United States and internationally and has gained particular attention for its climate change advocacy and for being entirely youth-run.
