Carried out to assess the environmental impact of products in each stage: extracting and processing raw materials, manufacturing and packaging, use and operation, disposal
Assessing the environmental impact of products in each stage: extracting and processing raw materials, manufacturing and packaging, use and operation, disposal at the end of its useful life
Allocating numerical values to pollutant effects is less straightforward and requires value judgements, so life-cycle assessment is not a purely objective process
Reduction in use, reuse and recycling of materials by end users reduces the use of limited resources, use of energy sources, waste and environmental impacts
