GHGE - Greenhouse Gas (GHG) Emissions, Measures the emissions of GHGs, often expressed in terms of CO2 equivalents. ValueUnit: kgCO2e.
BLUEWATER - Blue Water Footprint: Quantifies the consumption of surface and groundwater resources. ValueUnit: 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 with two indicators Nitrogen Emissions or Phosphorus Emissions, N or P.
Acidification Potential: Measures the potential of substances to cause acid rain (measured in moles of H+ or equivalent). Indicator: H⁺ Ion Acidification Potential, ValueUnit: Mol
Ozone Depletion Potential: Assesses the impact on the ozone layer (measured in kg CFC-11 equivalent). ValueUnit: KGCFC11E
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). Comparative Toxic Units (CTU)

Value Units and Unit Of Measure

Value units are the units related to the LCA indicator (e.g. for GHG Emissions this is kgCO2e) and the Unit of Measure is to define for what quanity this value applies (e.g. per meter, per kg or per piece). For units the Unified Code for Units of Measure is used to create UnitKeys for exahnge data.

Sameple LCA Data set

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: LCAGHG
- 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: LCAGHG
- IndicatorValue: 2,7
- IndicatorValueUnit: KGCO2E
- UomQty:1
- Uom:TI {TradeItem}
- 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 GRM
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
