2011 Application Submission

Application Addendum

Status: In Progress (2014 Update: This project has been rolled into Refills Not Landfills)

Project Description: This project hopes to reduce the purchase and disposal of single-use coffee cups on campus through a campaign entitled “Bring Your Own Mug”, brought to you by the Campus Environmental Management System Oversight Committee. This project will develop a campus wide monetary incentive program for bringing your own mug, will educate and reach the campus community through events and social media, and have sales and give-aways of tested, purchased BYOM mugs.

Goals: Put between 400-700 BYOM logoed mugs into the hands of campus community members through subsidized sales and free give-aways. Educate the campus about the environmental benefits (i.e. diversion of waste, reduction natural resource use) of BYOM. In 2009, campus sent 5,675 short tons of municipal waste to landfill. This project hopes to reduce this amount as well as assist the campus in achieving its goal of zero waste by 2020. Create a culture of BYOM and monetary incentive program that is used by all campus dining facilities and cafés. Track the decreasing purchase of single-use coffee cups by dining facilities and cafés.

Mission Statement

The Green Initiative Fund (TGIF) provides funding for projects that reduce UC Berkeley's negative impact on the environment and make UC Berkeley more sustainable. TGIF will allocate funds to projects that promote sustainable modes of transportation, increase energy and water efficiency, restore habitat, promote environmental and food justice, and reduce the amount of waste created by UC Berkeley. Portions of the fund also support education and behavior change initiatives, student aid (via return to aid), and internships. TGIF is supported by student fees and administered through a student-majority committee and a program coordinator.
