58 Ecology Emissions Only flights were able to be quantified for Scope 3 emissions. These fell to almost zero during the pandemic and rose again slightly in 2022. Constituting only 1%, the quantifiable and offset emissions falling under Scope 3 are insignificant, yet we will continue striving to reduce emissions in procurement (e.g. CO2-neutral printed materials), among employees (charging infrastructure for private vehicles), and the life cycle of our products to positively influence such emissions under Scope 3. In addition to CO2 emissions, we have set ourselves the objective of investigating whether it is possible to convert our solvent-based lacquer and paint systems over to using water-soluble products. To this end, we conducted an extensive study in conjunction with the Bern University of Applied Sciences in 2021 which unfortunately showed that water-soluble systems would not meet our requirements. The water-based systems performed worse in both chemical and mechanical resistance testing. What was decisive for us, however, was the visual appearance, where the water-soluble systems were unable to meet our requirements. Consequently, our VOC emissions will remain at 5 to 6 tonnes per year. Endingen site At the Endingen site, our CO2 emissions were also significant. NOx has been assessed, however will not be considered further at this point due to the very small amount of 0.1 tonnes. The situation with CO2 is very comparable to Bützberg. Under Scope 1, fossil fuels were foremost with 52%, followed by heating energy with 46%. On account of heating with natural gas, the heating energy CO2 emissions for Endingen are significantly higher than those for the 95% CO2-neutral heating using wood waste at Bützberg. The emissions under Scope 2 in Endingen also derive exclusively from electricity. According to the supplier, the electricity supplied in 2022 was CO2-free (already offset), meaning that the electricity in 2021 and 22 accounted for only 1% of total CO2 emissions. Under Scope 3, again only flights qualify and these account for 1% of Endingen’s total emissions. The non-quantifiable savings under Scope 3 include the efforts already mentioned for the Bützberg site. Roland Ammann
