Lifecycle Assessment data structure

This first example of a data point is for: The Greenhouse Gas emissions are 3,2 kgCO2eq per 1 kg product (for example for raw materials in food like salt or flour) measured at the warehouse of the seller, identified by GLN 1234567891023 (SRD= Ready for Dispatch)

  • IndicatorKey: GHGE
  • IndicatorName_ENG: Greenhouse Gas Emissions
    • IndicatorValue: 3,2
    • IndicatorValueUnit: kgCO2eq
    • UomQty:1
    • Uom:kg
    • LCATerm: SRD
    • PointofOrgin
      • GLN: 1234567891023
    • DestinationGLN:
      • GLN: 7834567891023

Second example The Greenhouse Gas emissions are 2,7 kgCO2eq per consumer unit (TradeItemID, for example for a can of 8 hotdogs), the value included the transport emission to the buyer (e.g. retailer) since the LCAterms are Delivered at Buyer (DAB), and value is based on location 7834567891023 (GLN)

  • TradeItemID
    • GTIN: 2365897158624
  • IndicatorKey: GHGE
  • IndicatorName_ENG: Greenhouse Gas Emissions
    • IndicatorValue: 2,7
    • IndicatorValueUnit: kgCO2eq
    • UomQty:1
    • Uom:CU {Consumer Unit}
    • LCATerm: DAB
    • PointofOrgin
      • GLN: 1234567891023
    • DestinationGLN:
      • GLN: 7834567891023

You can combine this data with the weigth & dimensions data for this Trade Item. In the example below a can of 8 hotdogs

  • GrossWeight: 500 gr
  • NetWeight: 450 gr
  • DrainedWeight: 300 gr
  • TaraWeight (packaging) = 500 -450 = 50 gram
  • 8 Pieces
  • 4 Portions

Now you can calculate:

  • GHG Emissions per Kg product including packaging, based on gross weight: 2,7kg/0,5 = 5,4 kgCO2eq per kg product
  • GHG Emissions per Kg c, based on gross weight: 2,7kg/0,5 = 5,4 kgCO2eq per kg product

List of LCA indicators

  • Greenhouse Gas (GHG) Emissions: Measures the emissions of GHGs, often expressed in terms of CO2 equivalents (kg CO2e).
  • Blue Water Footprint: Quantifies the consumption of surface and groundwater resources (cubic meters).
  • Energy Use: Assesses the total energy consumption, often distinguishing between renewable and non-renewable sources (megajoules or kWh).
  • Eutrophication Potential: Indicates the impact on aquatic ecosystems due to excess nutrients (like nitrogen and phosphorus), measured in kg of N or P.
  • Acidification Potential: Measures the potential of substances to cause acid rain (measured in moles of H+ or equivalent).
  • Ozone Depletion Potential: Assesses the impact on the ozone layer (measured in kg CFC-11 equivalent).
  • Resource Depletion: Evaluates the depletion of natural resources, both renewable and non-renewable (measured in kg of resource).
  • Waste Generation: Quantifies the amount and type of waste produced (measured in kilograms or cubic meters).
  • Toxicological Impact: Assesses the potential toxic impacts on human health and ecosystems (measured in comparative toxic units).
