About Us

San Diegans have a long history of protecting our clean air and water, spectacular natural resources and enviable quality of life. However, our region is vulnerable to diminishing water supplies, increased wildfire risks, coastal erosion and other impacts of climate change.

The San Diego Regional Climate Collaborative was founded on the belief that together we are prosperous and resilient. Our mission is to connect the region to advance climate change solutions. Together, we are prosperous and resilient.

What We Do

  • Support regional efforts and advance comprehensive solutions to reduce greenhouse gas emissions and prepare for local climate change impacts.
  • Communicate about the leadership of the Climate Collaborative and the San Diego region to local, state, and national leaders, peers, and funding institutions.
  • Build capacity within San Diego regional public agencies through networking, training and partnerships with academic institutions, businesses, and non-profits.

Advisory Board

The Board sets the strategy for the Climate Collaborative and works closely with the staff to implement this vision.  Our Board leadership consists of members from regionally focused planning agencies, cities, jurisdictions, nonprofit and academia. We welcome new Board members annually to join at the Leader member level and consider Board service.
