Sustainable Campus
Caltech aims to be one of the world's greenest colleges, conducting research that benefits the planet and piloting sustainable campus solutions for research institutions.
Today:
- One-sixth of the building space on campus is LEED certified Gold or Platinum by the U.S. Green Building Council.
- Drought-tolerant plants cover 17 percent of the campus.
- Turf replacement projects in 2021 alone save more than 380,000 gallons of water per year.
- More than half of the Caltech community walks, bikes, or takes public transit to campus, and some employees work from home.
