Life Cycle Assessment

Life Cycle Assessment (LCA) is a “cradle to grave” method of quantifying environmental impacts. Rather than only accounting for what can be observed on campus during or at Homecoming Weekend, using an LCA framework allows the inventory of inputs and outputs associated with Homecoming Weekend at any stage before (upstream), during, and after (downstream) Homecoming Weekend. These upstream and downstream stages often produce a significant share of total impacts so an assessment that includes these stages offers a more complete understanding of impact sources and more opportunities to improve environmental performance.

A large event such as Homecoming Weekend has many components with upstream and downstream stages. There are three major types of life cycle areas that can be applied to most aspects of Homecoming Weekend: Energy Use, Food & Beverage, and Material & Goods. Check out the information below to get a better idea of how each life cycle area plays a part in Homecoming activities. Then, check out the Results page to see the impacts that each area plays.
