Determining the energy and electricity mix

We pay attention not just to the quantity of energy consumed, but also to its quality and therefore to its carbon footprint. In accordance with our procurement policy for renewable energy published in 2020, we procure our energy wherever possible from sources that are renewable or produce low CO2 emissions. These include primarily hydropower, photovoltaics, wind power and, to a lesser extent, biomass for heating systems.

At 87%, electricity accounts for the largest share of our total energy con­sump­tion. We are committed to the use of 100% electricity from renewable energies and are a member of RE100, an in­ter­na­tional initiative to promote electricity from renewable resources. We obtain our renewable energy through three mechanisms:

  • We have our own photovoltaic systems.
  • We purchase the majority of our hydroelectricity from es­tab­lished suppliers in Switzer­land.
  • We buy certificates of origin (HKN) for the non-renewable part of the energy mix.

As a result, the proportion of renewable energy used in the year under review, as in previous years, was 100%, as verified by the independent inspection authority SGS.
