Product Carbon Footprint Analysis for drinking water supply using the GROHE BLUE kitchen tap in a working environment (2013)

Project partner: GROHE AG (Düsseldorf)

Beginning in July 2013, the Chair of Production and Logistics of the Georg-August-University Göttingen, Germany, and GROHE AG from Düsseldorf, Germany, are performing a Product Carbon Footprint analysis for drinking water supply using the GROHE BLUE® kitchen tap in a working environment. This system transforms ordinary tap water into carbonated drinking water by filtering it, cooling it down and charging it with carbon dioxide. Results from this analysis are compared to life cycle GHG emissions for bottled water and water-jugs to assess potential benefits of using the GROHE BLUE® system.

The Product Carbon Footprint for GROHE BLUE® drinking water is carried out using the Umberto NXT LCA software with ecoinvent databases. In accordance with ISO 14067 and PAS 2050:2011 standards, all up- and downstream processes concerned with the provision of sparkling water are taken into account. Data for material and energy consumption is supplied by GROHE AG. Missing information is derived from literature and own calculations. Data for the GHG Emissions of the comparator systems are taken existing studies.
