            What is LCA?
            • A key quantitative environmental tool.

            •    Analyses product impact across its entire life cycle
                  – Materials abstraction
                  – Manufacturing
                  – Distribution
                  – Use
                  – Disposal

            •    Identifies areas where environmental impact is highest

            •    Can Indentify where cost and environmental savings can be made

            •    Provides a quantitative analysis of how a product performs environmentally

            •    LCA needs to be done accurately or can be misleading

            •Goal & Scope definition, the product or service to be assessed is defined, a
            functional basis for comparison is chosen and the required level of detail is
            defined.

            •Inventory analysis of extractions and emissions. An inventory list of all the
            inputs and outputs of a product or service.

            •Impact assessment the effects of the resource use and emissions generated
            are grouped and quantified into a limited number of impact categories which
            may then be weighted for importance.

            •Interpretation, the results are reported in the most informative way possible
            and the need and opportunities to reduce the impact of the product(s) or
            service(s) on the environment are systematically evaluated.
