Cal Poly continues to make progress on its goal of carbon neutrality by 2050. In 2019, greenhouse gas emissions from the campus’ built environment (Scopes 1 & 2) were 19 percent below the 2015 baseline year, and 28 percent below 1990 levels. Accelerated installation of renewable energy generation across the state from solar, wind, and other renewable energy sources have resulted in over 85% percent of Cal Poly’s purchased grid electricity coming from carbon-free sources—up from 59 percent in 2015. Additionally, with the completion of the 4.5 MW Gold Tree Solar Farm in May of 2018, 22 percent of Cal Poly’s total electricity needs are now being met by on-site solar generation, with more solar projects in development.
