- GHGE - Greenhouse Gas (GHG) Emissions, Measures the emissions of GHGs, often expressed in terms of CO2 equivalents (kgCO2e).
- BLUEWATER - Blue Water Footprint: Quantifies the consumption of surface and groundwater resources (cubic meters).
- ENERGYUSE - Energy Use: Assesses the total energy consumption, often distinguishing between renewable and non-renewable sources (megajoules or kWh).
- EUTRHOPPOT - 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).

This first example of a data point is for: The Greenhouse Gas emissions are 3,2 kgCO2e 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
- IndicatorValue: 3,2
- IndicatorValueUnit: kgCO2e
- 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
- IndicatorValue: 2,7
- IndicatorValueUnit: kgCO2e
- 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
