A program of Kupu and Kōkua Hawaiʻi Foundation, the Hawaiʻi Youth Sustainability Challenge (HYSC) empowered Hawaiʻi youth to create solutions to conservation and sustainability challenges in their schools and communities. The solutions to the challenges—either identified by the students themselves or inspired by community partners—were student-driven. Selected students were in grades 9-12 and received funding (up to $1,000), guidance, and training to support their innovative and grassroots environmental initiatives. Exemplary student teams were selected to present at the annual Hawaiʻi Conservation Conference.
