Scope 3
In 2020, packaging data in Switzerland was newly collected. Adjustments (as shown below) lead to significant increase in Scope 3 compared to previous year. However, the difference between the recalculated 2020 total is < -1% despite the expansion of the corporate standard (see below). - Expansion of the corporate standard and data collection (i.e. commuting and packaging data). As part of the expansion of Scope 3, data on commercial products, product use and EoL (end of life of products) will be included in the company model in the medium term. Furthermore, the existing data collection/quality will be continuously improved wherever possible. In 2021, the system boundaries were expanded to include, for the first time, part of the commercial products purchased. The quality and the granularity of the collected goods transport data (transport to customers and within the production network) have been significantly improved. The same applies to metal and polymer data. In 2022 raw material and commercial goods data from new central data source, so the modelling could be extended and the data granularity and quality was further improved.
