Sustainable Sips: “Mug Club” Brews Climate Action
Students are transforming reusable mugs into a community ritual–reducing waste while rebuilding campus culture.
The Cardinal Green Office Program utilized a building evaluation process to recommend simple steps occupants could take to reduce their environmental footprint, and offered support in implementing those changes. Through the program, savings have varied from building to building, but some have realized a 20 percent decrease in monthly electricity usage. Nearly 100 buildings have gone through the Cardinal Green Office Program for a total energy reduction of more than 160,000 kWh, or $32,000 annually.
The program included an audit of the building, tailored recommendations, and access to an online resource center. The Office of Sustainability (OOS), in collaboration with the Woods Institute and various units in Sustainability, Utilities & Infrastructures, and Zones Management, launched the Cardinal Green Office Program as a platform for Stanford’s schools and departments to educate occupants and implement sustainability practices at the building level. In its last year, more than 30 buildings enrolled in the program.
After the program enrollment process, OOS guided building occupants through the following process to increase sustainability performance on their floor:
