‡ Biogenic carbon dioxide (CO2) emissions were 140 t in 2022.

Environmental impact: all figures 2018–2021 calculated using ecoinvent database version v38, 2022 v391

GHG emissions: values according to published GHG Inventories. Used ecoinvent database versions: 2018 v35, 2019 v36, 2020 v371, 2021 v38, 2022 v391; based on IPCC2013 (2018 -2021) and IPCC2021 for 2022.

Scope 1  

2019: Too low a value for Pfäffikon heating oil. Detected during data collection 2020 but not adjusted. Difference: +440 MWh resp. +120 t CO2eq

Scope 2  

Data are market-based. Location-based emission data have been and will be published on the CDP platform.

Scope 3  

Packaging data CH: in 2020 also newly collected for 2019 but not adjusted. Difference: +2000 t CO2eq

2020: Adjustments (as shown below) led to significant increase in Scope 3 (2020) compared to previous year. However, the difference between the recalculated 2019 to 2020 total is < -1 % despite the expansion of the corporate standard (see below).

• ecoinvent v371 remodeled the metal sector strongly increasing the CO2 footprint of copper.

• 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 were taken from a new central data source, enabling an extended modelling and a further improved data granularity and quality.

GHG emissions included were from purchased goods and services, fuel- and energy-related activities (not included in scope 1 and 2), waste generated in operations, business travel, upstream transportation and distribution, and commuting (see Figure 8 in chapter "Greenhouse gas emissions and climate change").
