City Green Cup is a gathering for students who are making their communities and society better, more interesting places. Share what you are building, discover what others are doing, and meet people and organizations who can help you move forward.

Ideas are welcome. We especially want to support teams ready to take their first step, as well as those already putting their ideas into practice. The connections made here should last beyond one day.

We want the people, projects and partnerships that meet at the Cup to keep moving long after the event. That lasting network is what we are here to build.

MORE THAN A COMPETITIONMeet, share, connect, create, act.
