What is a Green Life Cycle? This includes impacts along the entire continuum of a products life from raw material extraction, through manufacturing, distribution and transportation, use, recycle, and ultimately to final disposal.

What is Life Cycle Analysis? LCA is a systematic cradle-to-grave analyses of production systems tool to estimate the environmental consequences of alternative materials, designs, manufacturing processes, product use patterns, and end of life alternatives. The assessment includes the entire life cycle of the product, process or activity, encompassing, extracting and processing raw materials; manufacturing, transportation and distribution; use, re-use, maintenance; recycling, and final disposal. The next LCA step is to conduct a life cycle impact assessment. The impact assessment focuses on the potential environmental and human health impacts associated with a given product system based on the life cycle inventory results. Analysis of multiple environmental and resource issues (i.e.: inputs and outputs). Final phase is an improvement analysis to evaluate opportunities to reduce energy, material inputs, or environmental impacts at each stage of the product life-cycle. After analysis comes implementation (press here for more).

Bristol-Myers Squibb - Product life cycle reviews form the cornerstone of BMS's prevention-based EHS activities (press here).   In 1992, BMS committed to completing Product Life Cycle reviews of all major product lines by the end of 1997, establishing a company wide commitment  to leadership in EHS management.  The teams participating in PLC reviews were able to identify and reduce negative EHS impacts throughout all phases of a  product's life, from research to final disposal.  The teams also identified potential  savings of more than $6.5 million in product and process improvement opportunities, benefiting both the environment and business.
