we are a force for change

The School of Climate, Environment, and Society (CES) is Clark University’s global hub of research and learning designed to advance sustainable futures.​ Rooted in community and connected across the world, CES prepares emerging leaders for careers by empowering them to think critically and across systems to address society’s greatest challenges. ​At CES, students experiment boldly, and work hand-in-hand with faculty to build applied solutions through experiential learning and meaningful partnerships. ​​

Achieving positive change

Study and work alongside others to untangle the interconnected climate, environmental, societal, and economic crises, and develop solutions.
