life cycle assessment
Life Cycle Assessment is a process to:
evaluate the environmental burdens associated with a product, process, or activity by identifying and quantifying energy and materials used and wastes released to the environment,
assess the impact of those energy and materials used and releases to the environment; and
identify and evaluate opportunities to affect environmental improvements.
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.
