Meaning

A life cycle assessment is a technique to assess environmental impacts associated with all the stages of a product's life from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling.

About Life Cycle Assessments

A life cycle assessment includes information on the energy needed and the waste produced during:

Extraction the raw material
Purification of materials
Manufacture of the product
Use, maintenance and repairing of the product
Disposal or recycling of the product

A life cycle assessment of a product will show:

Emission of gases into the atmosphere
Emission of waste products into rivers or the ocean
Production of solid waste for landfills
Coproducts made during manufacture that are useful elsewhere
Energy required at each stage of a product's life cycle
