Life Cycle Assessment
Lifecycle Assessment (LCA) is an approach used to quantify the environmental and social impacts of a product by measuring the inputs (e.g. raw materials and energy) and outputs (e.g. greenhouse gases) associated with its entire supply chain.
The life cycle of a given product is made up of thousands of linked processes (called “unit processes”) that are each required in support of the production and use of a given product. All unit processes have their own inputs and outputs that impact ourand are measured as part of the LCA. The LCA then results in a rich set of data -- a laundry list of impacts at the unit process level -- that can be loaded into a database. The resulting database is the life cycle inventory (LCI) and provides a detailed description of all impacts associated with each process in a product’s life.
The final LCA identifies areas where process changes, potentially enabled by new
