Life Cycle Inventory & Life Cycle Assessment
"Life cycle assessment" - means assessing the entire life cycle of the product, process or activity, encompassing extracting and processing material; manufacturing, transporting and distribution; use, reuse and maintenance; recycling and final disposal. (The Society of Environment, Toxicology and Chemistry, 1993)
This powerpoint presentation, prepared by faculty in the Division of Agriculture at the University of Arkansas, provides an overview of the life-cycle assessment process.
Life Cycle Assessment is a powerful tool to measure the environmental and social impacts of products. In order to overcome the cost and time burdens associated with these studies so that broad adoption can occur, a new approach is needed that fosters the collaborative creation of modular LCI data that can be leveraged by all who want to add value to the process. Open source LCA/LCI provides a framework for accelerating the adoption of LCA methods to inform purchasing decisions that will lead our consumer goods economy toward a sustainable future.
The Center for Agriculture and Rural Sustainability at the University of Arkansas conducted a life cycle assement of global cotton production quantifying the energy required at each phase of production, thereby allowing a comparison of energy intensity across an array of production methods.
