The University System has or is in the process of hiring a sustainability coordinator at each of its campuses (a system-wide sustainability specialist is already on staff), who will help the University work towards the State of California's goal of reducing greenhouse gas emissions to 80 percent below 1990 levels by 2050. All new buildings will be LEED Certified at the minimum, if not Silver-rated, and the University's goal for purchases of electricity from the grid is that 20 percent of its electricity come from renewable sources by 2017. Four campuses have joined the California Climate Action Registry (CCAR) and are cataloging greenhouse gas emissions; other campuses are exploring joining the CCAR.
