109 Group Management Report Österreichische Bundesbahnen-Holding Aktiengesellschaft Consolidated Financial Statements | Group Management Report 66 Decarbonization effects relating to the decarbonization areas of mobility, buildings and Scope 3 emissions (assessed on a linear basis over the respective impact periods): – Mobility: decarbonization effects of defined actions in the period from 2022 (base year) to 2025: 8,064 tons (2022–2024: 4,148 tons) – Buildings: decarbonization effects of defined actions in the period from 2022 (base year) to 2025: 7,228 tons (2022– 2024: 4,819 tons) – Scope 3 emissions: decarbonization effects of defined actions in the period from 2022 (base year) to 2025: Scope 3.3: 4,067 tons (2022–2024: 2,405 tons); lower measurement for Scope 3.1 and 3.2 in the base year 2022 by 595,162 tons and in 2025 by 861,955 tons due to partial exclusion from the spend-based method (2024: reduction of 779,398 tons) Since 2021, the ÖBB Group has voluntarily published the key figures for Taxonomy-eligible revenue, CapEx, and OpEx. Further information and the financial key figures for 2025 can be found in Chapter E.2 “Environmental information” under “Voluntary implementation of the EU Taxonomy Regulation in the ÖBB Group.” The actions listed in the tables are assigned to the following Taxonomy-aligned or Taxonomy-eligible economic activities for each decarbonization lever. Decarbonization levers* ) Economic activity/activities Replacement of diesel CCM / CCA 6.1, CCM / CCA 6.2, CCM / CCA 6.3, CCM / CCA 6.5 Increase energy efficiency CCM / CCA 7.2 / 3.2, CCM / CCA 7.3 Increase in own energy supply CCM / CCA 4.1, CCM / CCA 4.3, CCM / CCA 4.5, CCM / CCA 4.10 Modal shift to railway CCM / CCA 6.1, CCM / CCA 6.2, CCM / CCA 6.3, CCM / CCA 6.5 Phasing out fossil fuels CCM / CCA 7.3, CCM 7.2 / C 3.2 Targeted reduction of further Scope 3 emissions or procurement of capital / consumer goods and services not covered *) ESRS E1-3.29.c. Climate change adaptation – Portfolio Detailed information on climate change adaptation can be found in this chapter under “Climate change” in the section “Material impacts, risks, and opportunities and their interaction with strategy and business model.” A further specification of the targets and directions with regard to climate change adaptation was carried out in 2025. In the course of this, the necessary specification of action plans were also carried out. An excerpt of the action plans already underway can be found below: ESRS E1-3.29.a, b *) MDR-A.68.a, b, c, e. Action plans for climate change adaptation (excerpt) Action Brief description *) Time horizon Retrofit flood protection for the most exposed tunnel structures (rail infrastructure): A range of flood protection action plans (e.g. portal bulkheads, upgrading of pumping systems if necessary, etc.) will be implemented at the most exposed tunnel structures. Being implemented Integration of climate risk analyses as a fixed component of the planning process for new build and expansion projects in infrastructure developments. Being implemented Preventive tree removal – “railway accompanying forest”: Through preventive tree removal, the impact on the railroad caused by falling trees or falling tree parts in the event of strong winds, snow, and ice is reduced as much as possible, thereby further increasing availability and safety. This reduces disruptions to rail traffic. Ongoing Upgrade of active cooling in the passenger compartment of local transport (NV): Through the ongoing phasing out of non-air-conditioned vehicles and the use of new air-conditioned vehicles, the passenger transport fleet will be equipped with 100% air-conditioned vehicles in the long term. Being implemented Upgrade of air-conditioned driver’s cabs. Being implemented Servicing of components such as air conditioning systems, cooling technology and vehicle electronics: During maintenance, increased attention is paid to the cleaning condition of the cooling elements / heat exchangers. Being implemented Implementation and further development of regular climate risk and vulnerability analyses for all relevant subgroup companies.
