Information on Wacker Chemie AG

In addition to the information on the WACKER Group provided in the combined non-financial report, the key indicators for Wacker Chemie AG are given below.

Wacker Chemie AG is the parent company of the WACKER Group and has its headquarters in Munich, Germany. It operates through four business divisions: WACKER SILICONES, WACKER POLYMERS, WACKER BIOSOLUTIONS and WACKER POLYSILICON. Wacker Chemie AG also has corporate departments, which provide services to the Group as a whole. The key performance indicators used in corporate management are implemented groupwide in the business divisions. Corporate goals are defined and reported for the divisions on a groupwide basis. Even though Wacker Chemie AG is an independent entity, no separate key performance indicators are defined or reported for it. That also applies to matters such as sustainability and non-financial performance indicators. For more information, please refer to the respective details provided for the WACKER Group as a whole.

CO2e = CO2 equivalents, as defined in the Greenhouse Gas Protocol CO2 emissions are measured on the basis of the Greenhouse Gas Protocol of the World Resources Institute and World Business Council for Sustainable Development, “A Corporate Accounting and Reporting Standard” (GHG Protocol).
Scope 1: direct CO2 emissions.
Scope 2: indirect emissions from the consumption of purchased energy (converted into CO2 equivalents for purchased electricity, steam and heat).

2

CO2 emissions are split into fossil and biogenic sources in accordance with the GHG Protocol. Biogenic emissions arise from the combustion or decomposition of renewable raw materials.

3

The HFC category contains minor quantities of emissions from other partially halogenated HFCs which contribute to the greenhouse effect as well. The GWP factors of the individual substances were used as a basis for calculating the effects of hydrofluorocarbons. The factors range from 5.5 to 14,600 kg CO2e/kg HFC.

4

The electricity volumes supplied by the affiliated company Alzwerke GmbH are included in indirect CO2 emissions in a climate-neutral manner due to the fact that they are not fed into the public electricity grid. Since 2020, indirect CO2 emissions have also included methane and nitrous oxide emissions converted into CO2 equivalents. Purchased electricity volumes are converted into CO2 emissions using emission factors from "CO2 Emissions from Fuel Combustion, 2023 Edition, respectively" issued by the International Energy Agency (location-based).

5

The electricity volumes supplied by the affiliated company Alzwerke GmbH are included in the indirect CO2 emissions in a climate-neutral manner due to the fact that they are not fed into the public electricity grid. Purchased electricity volumes are converted into CO2 emissions using the emission factors of the electricity suppliers (market-based). If the emission factors for the respective suppliers are not available, the residual-mix emission factors are used or the emission factors of EEI (Edison Electric Institute), eGRID (United States Environmental Protection Agency) or the International Energy Agency.
