Sustainability through Purchasing Services

  • Caltech's goal of becoming a more sustainable campus can only be achieved if those that we purchase from are made aware of that goal and agree to adhere to the practices that support it.
  • By holding suppliers to the same standards and practices to which Caltech adheres, they are considered partners in that effort.
  • Caltech faculty, staff, and students are all responsible for ensuring that their purchases from outside Suppliers can indeed fulfill both the items/services and the sustainable practice efforts required.
  • Before that can happen, the Caltech community must first educate themselves on the sustainable requirements and practices of responsible purchasing.
  • Learn more about practicing sustainable purchasing.
