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.See
- 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.
