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.

Basic Lifecycle Analysis- For Domestic White Goods
• Extraction + Manufacture: mass (kg) X 50 MJ/kg
• Transport : 1 MJ airplane energy per item 1 MJ road per item Return car journey X 50MJ/ no of items purchased
• Use
- Electrical: watts X seconds (time in use (seconds) X times per day X days X life (years)) X 3*/1,000,000
• MJ to KWh X 0.277. • CO2 Emissions 1kWh = 0.624 kg CO2 for Irish energy supply.
- Material: mass (kg) X 50MJ/kg
- Disposal: mass (kg) X 2MJ/kg (landfill direct cost)* Refers to Electrical efficiency Source: Erik Billet, Brunel University
