d. Base year for the calculation, if applicable, including:
i. the rationale for choosing it;
ii. emissions in the base year;
iii. the context for any significant changes in emissions that triggered recalculations of base year emissions.

e. Source of the emission factors and the global warming potential (GWP) rates used, or a reference to the GWP source.

f. Consolidation approach for emissions; whether equity share, financial control, or operational control.

g. Standards, methodologies, assumptions, and/or calculation tools used.

a. Scope 1 Greenhouse gas emissions amounted to a total of 2,891,322 tons CO2 (Coverage 100%).

c. Data not available

d. All data usually refer o the previous fiscla year and the related forecast

e. Sources for carbon conversion factors: GHG Protocol, DEFRA and Germany’s Federal Environmental Agency, NGER

f. Financial  control: The coverage indicates the coverage of data in relation to Group work done. 

g. GHG Protocol, DEFRA und Germany’s Federal Environmental Agency, NGER

d. Other indirect (Scope 3) GHG emissions categories and activities included in the calculation.

e. Base year for the calculation, if applicable, including:
i. the rationale for choosing it;
ii. emissions in the base year;
iii. the context for any significant changes in emissions that triggered recalculations of base year emissions.

f. Source of the emission factors and the global warming potential (GWP) rates used, or a reference to the GWP source.
