Defining The Purpose

The decision to perform an LCI is usually based on one or more of the following objectives:

To establish a baseline of information on a system's overall resource use, energy consumption, and environmental loading To identify the stages within the life cycle of a product or process where a reduction in resource use and emissions can be achieved To compare the system's input and output associated with alternative products, processes, or activities To guide the development of new products, processes, or activities toward a net reduction of resource requirements and emissions To identify areas to be addressed during life cycle impact analysis.
