Key Performance Indicators to criteria 13

Key Performance Indicator GRI SRS-305-1: Direct (Scope 1) GHG emissions
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.

  2020 2019 2018
Fleet [t CO2] 23,53 32,49 33,52
Gas [t CO2] 7,51 5,80 8,01
Since 2017: no values for CCH due to revitalization. The values are dependent on the weather, years when events are strong or weak, and energy-related conversions. Corona-related deviations are possible.

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.

  2020 2019 2018
Green electricity from hydropower [t CO2] 15,92 26,57 31,75
Residual district heat [t CO2] 1.602,22 1.829,25 2.177,53
Since 2017: no values for CCH due to revitalization. The values are dependent on the weather, years when events are strong or weak, and energy-related conversions. Corona-related deviations are possible.

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.

Scope 3 of 'Other Indirect Emissions' at HMC primarily comprises items such as service partner trips to and from the premises as well as transport of exhibitors and visitors to and from events. A potential method to document these emissions and a compensation approach are being investigated.  

In 2020, the most important service partners were asked to provide information on the frequency of trips, distances travelled, and means of transport used for HMC’s CO2 balance sheet.

In a scientific study conducted in 2019, visitors of two events where asked in a random survey (n = 335) about their means of transport to and from the respective event (also refer to the 2019 sustainability report under GRI SRS-305-3: Other Indirect GHG Emissions (Scope 3) in the database or on pages 39-40 of the CI document which can be found on the HMC Website).

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.
