We continue to improve data collection so that observing our disposal patterns can more effectively inform our purchasing practices. The Yale community can help contribute by using materials wisely: reducing the
volume of materials that come onto campus, choosing reusable over single-use items, and ensuring proper disposal once a material reaches the end of its life. We have an opportunity to convey these practices broadly, so that even those who may only be passing through understand the importance o sustainability at Yale.

Since 2013, paper purchases have decreased by 26.4% and office supply purchases have decreased by 15.7%.
