Gross Scope 1, 2 and 3 GHG emissions and total GHG emissions

Definition and calculation method

All emissions have been converted into and are stated in CO₂ equivalents.

Scope 1

• All fully consolidated HHLA subsidiaries and the at-equity subsidiaries KTH, HVCC, FKZ and Stein are included.
• The emission factors for refrigerants, fuels and heating gas are based on data from the IPCC, DEFRA and GLEC.

Scope 2 (location-based)

• The current data from the International Energy Agency (IEA) is used as location-based emission factors.
• All fully consolidated HHLA subsidiaries and at-equity subsidiaries are included: KTH, HVCC, FKZ and Stein.

Scope 2 (market-based)

• The emission factors reported by the particular energy supplier are used as market-based emission factors. If these are not available, location-based emission factors are used.
• All fully consolidated HHLA subsidiaries and at-equity subsidiaries are included: KTH, HVCC, FKZ and Stein.

Scope 3, Category 1 (Purchased goods and services)

• Scope 3.1 emissions were accounted for all fully consolidated HHLA companies, including the at-equity subsidiaries KTH, HVCC, FKZ and Stein. Eurotrans was not included.
• The emission factors are taken from the EXIOBASE database (as of 2019) and are adjusted for inflation.

Scope 3, Category 2 (Capital goods)

• Scope 3.2 emissions were accounted for all fully consolidated HHLA companies, including the at-equity subsidiaries KTH, HVCC and FKZ. Eurotrans was not included.
• For large equipment for which a Product Carbon Footprint (PCF) is available, this was used as the basis for the calculation, taking into account all life cycle phases except the use phase. Emissions for large equipment without a PCF were calculated weight-based by querying the manufacturer, equipment type and total weight at the HHLA subsidiaries. If this data is missing, it is researched online or replaced with data from a comparable appliance.
• The emission factors are taken from the EXIOBASE database (as of 2019) and are adjusted for inflation. The emission factor for steel was purchased from the consulting firm Sphera (reference year 2024).

Scope 3, Category 3 (Fuel- and energy-related activities)

• Scope 3.3 emissions were accounted for all fully consolidated HHLA companies, including the at-equity subsidiaries KTH, HVCC, FKZ and Stein.
• The calculation is based on the latest emission factors available from the IEA and DEFRA.
