Mentorship and Coaching

Because the intersection of business and the environment is a relatively new space, there is a lot of room for new ideas to take root. CBEY supports students interested in the creation of new nonprofit and commercial organizations, business models, or other innovations that address pressing environmental challenges. 


Various CBEY staff are available for office hours or 1-1 coaching sessions and feedback on your venture or idea.  Open to members of the Yale Community. 

  • Peter Boyd, CBEY Executive Fellow 
  • Vincent Stanley, Director of Philosophy at Patagonia
  • Cass Walker, Social and Environmental Innovation Program Manager at CBEY
