American College & University Presidents’ Climate Commitment. for the Advancement of Sustainability in Higher Education

Sustainability Initiatives Commit to building all new buildings to LEED Silver or higher certification. Purchase Energy Star compliant appliances in new & renovated buildings. Begin a recycling program Make energy improvements throughout the campus infrastructure, such as enclosing open air breezeways, digital controls, energy management system Pay for print (reduced paper usage in labs by 90%) Trayless dining in cafeteria Summer schedule of 4 ten hour days and closing many buildings on Fridays Participated in the National Teach-In Flagship campus for Earth Hour Host Earth Day activities for Girl Scouts Start a bike sharing program Promote spsu.zipride.com, a carpool-matching website Retrofit library to reclaim some of the original design energy saving features Completed an emissions inventory (improving that calculation with better data) Create a climate action plan for the University Integrating sustainability education across the curriculum.
