Strengthening the Mills commitment to sustainability—and, inextricably, social justice—is a strategic imperative for the College. We have a number of sustainability goals that we have met or are on track to meet in areas such as water conservation and waste reduction. Mills is a signatory of the American College and University Presidents’ Carbon Commitment to minimize our environmental impact, and we exceeded our goal of a 15% reduction of greenhouse gas emissions.
