Climate, Energy, & Environment Professional Interest Council

A Student-Run Organization at Harvard Kennedy School

Mission: The Climate, Energy, and Environment Professional Interest Council (CEEPIC) provides a focused community for Harvard Kennedy students to explore and engage with the complex challenges of the global climate crisis. Each semester, CEEPIC organizes a variety of events related to climate, energy, and the environment that bring students together with faculty, policy makers, and subject matter experts. 

CEEPIC also works in partnership with the Sustainability Leadership Council to identify opportunities to integrate conversations about climate, energy, and the environment as core parts of the HKS curricula and student experience.

CEEPIC events are open to HKS students and the wider Harvard community. Our members' interests span many different policy domains, and we strive to ensure the diversity of perspectives, expertise, and lived experiences among our members is reflected in our programming.
