Both water withdrawn from wells and water withdrawn from the mains water supply belong to the freshwater category (<1,000 mg/L total dissolved solids). All water discharged belongs to the freshwater category (<1,000 mg/L total dissolved solids) and goes entirely into the public sewage system, i.e. third-party water. Water consumption corresponds to the difference between water withdrawal and water discharge. The figure for water withdrawal remains more or less constant between 2020 and 2021. The metering system was refined in 2021, enabling a more precise breakdown between the amount of water “consumed” (i.e. water for irrigating green areas) and “discharged” (i.e. water going to the sewage system), which is why the figures show an increase of approximately 500 cubic metres of water consumed compared to 2020.
To calculate GHG emissions, the emission factors considered for ISO 14064 certification were used, with the exception of market-based (Scope 2) emissions. To calculate direct (Scope 1) GHG emissions, we used emission factors taken from the “Defra - Department for Environment, Food and Rural Affairs” database (2018-2019-2020). To calculate indirect (Scope 2) GHG emissions, we used the emission factors published by Defra and ISPRA for the location-based approach, and by the Association of Issuing Bodies within the “European Residual Mixes” (2018-2020) for the market-based approach. Specifically, mean emission factors relating to the specific national electricity production mix are used under the location-based approach, while a virtual zero emission factor is used for energy purchased and certified as renewable (e.g. Go).under the market-based approach.
