Harvard Chan C-CHANGE taps into the collective knowledge of student leaders at the Harvard Chan School, through our Student Ambassador Program.

This year-long program equips Harvard Chan master and doctoral students with critical skills to become climate and health leaders. The program cultivates a community of students at Harvard Chan who are interested in climate change, strengthens the connections between the Center and departments across the school, and helps students understand how climate change impacts their respective fields of study.
