The reporting organization shall report the following information:

a. Gross direct (Scope 1) GHG emissions in metric tons of CO2 equivalent.

b. Gases included in the calculation; whether CO2, CH4, N2O, HFCs, PFCs, SF6, NF3 or all.

c. Biogenic CO2 emissions in metric tons of CO2 equivalent.

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.

Scope 1: Direct greenhouse gas emissions in tonnes of CO2 equivalents 
  Spezifikation Einheit 2016 2017  
Administrative locations1) Emissions from fossil fuels (petrol, diesel, natural gas, petroleum) t CO2e 446 520  
Emissions from biogenic sources (pellets) t CO2e 0.06 0.06  
Portfolio2) Emissions from fossil fuels (natural gas, petroleum) t CO2e 137,275 140,838  
Emissions from biogenic sources (pellets) t CO2e 151 152  

1) The values represent the direct climate emissions (Scope 1) based on the energy consumption values for the administrative locations adjusted to reflect weather conditions. The Scope 1 value is calculated using the emission factors of the Institute for Living and the Environment (Institut Wohnen und Umwelt – IWU) and the emission factor for the German electricity mix of the German Environment Agency (UBA) (527 g CO2e/kWh). 

2) The values represent the direct climate emissions (Scope 1) based on the portfolio’s energy consumption. The Scope 1 value is calculated using the emission factors of the Institute for Living and the Environment (Institut Wohnen und Umwelt – IWU) and the emission factor for the German electricity mix of the German Environment Agency (UBA) (527 g CO2e/kWh).

Key Performance Indicator GRI SRS-305-2: Energy indirect (Scope 2) GHG emissions
The reporting organization shall report the following information:

a. Gross location-based energy indirect (Scope 2) GHG emissions in metric tons of CO2 equivalent.

b. If applicable, gross market-based energy indirect (Scope 2) GHG emissions in metric tons of CO2 equivalent.

c. If available, the gases included in the calculation; whether CO2, CH4, N2O, HFCs, PFCs, SF6, NF3, or all.

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.

  
Scope 2: Energy indirect greenhouse gas emissions in tonnes of CO2 equivalents 
  Spezifikation Einheit 2016 2017  
Administrative locations1) Emissions from electricity and district heating (location-based) t CO2e 1,301 1,356  
Emissions from electricity and district heating (market-based) t CO2e 787 815  
Portfolio2) Emissions from electricity and district heating (location-based) t CO2e 191,435 199,954  
Emissions from electricity and district heating (market-based) t CO2e 175,634 184,327  

1) The values represent the energy indirect climate emissions (Scope 2) based on the energy consumption values for the administrative locations adjusted to reflect weather conditions. The location-based Scope 2 value was calculated using the emission factors of the Institute for Living and the Environment (Institut Wohnen und Umwelt – IWU) and the emission factor for the German electricity mix of the German Environment Agency (UBA) (527 g CO2e/kWh). The market-based Scope 2 value is presented in order to illustrate the positive effects on the climate of sourcing certified green electricity. This value is made up as follows: emissions from district heating; 10% electricity emissions based on electricity mix factor for Germany (527 g CO2e/kWh) and 90% emissions based on green electricity factor (0 g CO2e/kWh).

2) The values represent energy indirect climate emissions (Scope 2) based on the portfolio’s energy consumption. The location-based Scope 2 value was calculated using the emission factors of the Institute for Living and the Environment (Institut Wohnen und Umwelt – IWU) and the emission factor for the German electricity mix of the German Environment Agency (UBA) (527 g CO2e/kWh). The market-based Scope 2 value is presented in order to illustrate the positive effects on the climate of sourcing certified green electricity. This value is made up as follows: emissions from district heating; 10% electricity emissions based on electricity mix factor for Germany (527 g CO2e/kWh) and 90% emissions based on green electricity factor (0 g CO2e/kWh).

Key Performance Indicator GRI SRS-305-3: Other indirect (Scope 3) GHG emissions
The reporting organization shall report the following information:

a. Gross other indirect (Scope 3) GHG emissions in metric tons of CO2 equivalent.

b. If available, the gases included in the calculation; whether CO2, CH4, N2O, HFCs, PFCs, SF6, NF3, or all.

c. Biogenic CO2 emissions in metric tons of CO2 equivalent.

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.

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

Other indirect greenhouse gas emissions (scope 3) are generated, for example, by heat consumption of our tenants. We do not record this consumption, however, as the time investment required is disproportionately high, we therefore cannot derive any corresponding emissions volume.

Key Performance Indicator GRI SRS-305-5: Reduction of GHG emissions
The reporting organization shall report the following information:

a. GHG emissions reduced as a direct result of reduction initiatives, in metric tons of CO2 equivalent.

b. Gases included in the calculation; whether CO2, CH4, N2O, HFCs, PFCs, SF6, NF3, or all.

c. Base year or baseline, including the rationale for choosing it.

d. Scopes in which reductions took place; whether direct (Scope 1), energy indirect (Scope 2), and/or other indirect (Scope 3).

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

We report the corresponding key figures together with the disclosures on reducing energy consumption (GRI 302-4) in the performance indicators for Criteria 11 and 12.
