A student-led network where schools share sustainability initiatives that actually worked.
Explore the networkOur mission
Built by students, for students.
Schools everywhere are solving the same sustainability problems in isolation. Riza is a network where student sustainability representatives publish the initiatives they have actually run, with evidence of what worked, so that students at other schools can adopt them with proof behind them rather than starting from nothing.
It exists to turn student leadership from a title into genuine initiative — students who convene meetings, propose changes and carry them through.
