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).

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.

CH₄: methane emissions from fossil sources, without methane emissions from biogenic sources.

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.

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. Indirect CO₂ emissions also include 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,” 2021 and 2022 Editions, respectively, issued by the International Energy Agency (location-based).

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 the International Energy Agency.
