Overview
Life Cycle Assessment (LCA) is a systematic methodology used to evaluate the 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. LCA provides a comprehensive view of the environmental aspects and potential impacts of a product or service.
Objectives of LCA:
- Identify Improvement Opportunities: Pinpoint areas within the product life cycle where environmental impacts can be reduced.
- Support Decision Making: Inform policymakers and industry leaders in making more environmentally conscious decisions.
- Enhance Product Design: Aid in the development of more sustainable products by understanding their environmental footprints.
List of LCA impact indicators=
| Group | IndicatorKey | Indicator(eng) | Definition | ValueUnits |
|---|---|---|---|---|
| Emissions | LcaGghEmissions | Greenhouse Gas (GHG) Emissions | Measures the emissions of GHGs, often expressed in terms of CO2 equivalents | kgCO2e |
| Water | LcaBluewaterFootprint | Blue Water Footprint | Quantifies the consumption of surface and groundwater resources | CBM |
| Energy | LcaEnergyUse | Energy Use | Assesses the total energy consumption, often distinguishing between renewable and non-renewable sources | MJ or KWH |
| Eutrophication Potential | LcaNitroEmissions | H+ Nitrogen Emissions | Indicates the impact on aquatic ecosystems due to excess nutrients | MOL |
| Eutrophication Potential | LcaPhospEmissions | H+ Phosphorus Emissions | Indicates the impact on aquatic ecosystems due to excess nutrients | MOL |
| Acidification Potential | LcaAcidPotential | H⁺ Ion Acidification Potential | Measures the potential of substances to cause acid rain (measured in moles of H+ or equivalent) | MOL |
| Ozone Depletion Potential | LcaOzoneDepPot | Ozone Depletion Potential | Assesses the impact on the ozone layer | KGCFC11E |
| Resource Depletion | LcaRenewResDep | Renewable Resource Depletions | Evaluates the depletion of renewable natural resources | KG |
| Resource Depletion | LcaNonRenewResDep | Non-Renewable Resource Depletions | Evaluates the depletion of non-renewable natural resources | KG |
| Waste | LcaWasteGenerate | Waste Generation | Quantifies the amount and type of waste produced | KG or CBM |
