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 of sustainability at Yale.

Refer to this Sustainable Purchasing Guide for green recommendations. 

Paper purchases have decreased by 45.3% since 2013.
