ÖBB Annual Report 2025

Group Management Report 112 Österreichische Bundesbahnen-Holding Aktiengesellschaft Consolidated Financial Statements | Group Management Report 69 Notes on energy consumption trends – In the 2025 reporting year, total energy consumption in the ÖBB Group increased by 81,439 MWh compared to 2024. This increase can be seen both internationally with +2.3% or 16,514 MWh and domestically with +2.2% or 64,924 MWh. – The demand for energy from renewable sources continues to clearly predominate: in 2025, 2,031,359 MWh of renewable energy was required across the Group, compared to 1,737,196 MWh from fossil sources. In Austria, 2,030,564 MWh come from renewable energy sources (corresponding to approx. 67% of total energy demand), internationally 796 MWh or 0.11%. – Total energy demand from fossil sources in Austria fell slightly by 678 MWh in the 2025 reporting year compared to 2024, while it rose by 16,259 MWh internationally. – Diesel consumption across the ÖBB Group increased slightly by 5,604 MWh in 2025 compared to 2024. In Austria, diesel consumption fell by 7,291 MWh compared to the prior year, while international consumption rose by 12,895 MWh. – The utilization of self-generated renewable energy for traction current and three-phase current in Austria fell by 209,274 MWh year-on-year. In the traction current sector in Austria, the utilization of self-generated renewable energy also declined slightly, while three-phase electricity utilization increased slightly. – With regard to the 2035 climate targets, the ÖBB Group continues to show positive development domestically: diesel utilization in the mobility sector is falling, the use of metallurgical coke in buildings is at zero, and the utilization of heating oil and natural gas is also continuing to fall. ÖBB’s energy intensity on the basis of net revenue The following table shows energy intensity related to activities in high climate impact sectors. These figures were derived from total energy consumption and net revenue from activities in high climate impact sectors. For a list of high climate impact sectors according to ESRS, see sections A to H and section L (as defined in Commission Delegated Regulation (EU) 2022/1288). ESRS E1-5.41 Energy intensity based on net revenue in high climate impact sectors *) 2025 2024 Total energy consumption from activities in high climate impact sectors in MWh 3,768,555.6 3,687,116.3 Revenue (net earnings) in high climate impact sectors in EUR million 5,852.2 5,467.5 Energy intensity 644.0 674.4 *) The following high climate impact sectors were used: Section C – Manufacturing, Section D – Energy supply, Section F – Construction, Section H – Transportation and storage, Section L – Real estate activities. ESRS E1-5.40, AR 36; ESRS E1-5.42. Revenue from activities in high climate impact sectors in 2025 (EUR 5,852.2 million) differs only slightly from the total revenue in the ÖBB Group’s financial statements (EUR 6,155.5 million). ESRS E1-5.43. AR 38 Gross GHG emissions in Scope 1, 2 and 3 categories and total emissions ÖBB reports its gross GHG emissions separately according to Scope 1, Scope 2 and Scope 3 emissions. The information in the following tables includes all fully consolidated companies in the Group and is broken down by domestic and foreign companies as well as by decarbonization areas. ÖBB has no operational control over affiliated companies. GHG emissions from equity investments are reported under Scope 3.15. ESRS E1-6.50 When calculating GHG emissions, ÖBB observes the principles, requirements and guidance of the GHG Protocol Corporate Standard. The emission factors employed to measure the quantities of energy used in the ÖBB decarbonization areas of mobility and buildings (domestic = AT and abroad) are generally provided by Environment Agency Austria. For traction current in Austria, the emission factor is calculated annually on the basis of the Guarantees of Origin confirmed by the auditor. The emission factors are as up-to-date as possible. For traction current in Austria, they refer to electricity mix data from 2024. They also refer to CO 2 equivalents. This takes into account the climate impact of the different GHG emissions. In addition, the values for global warming potential (GWP) published by the IPCC were used to calculate the CO 2 equivalents for emissions. Furthermore, ÖBB does not operate any installations that are subject to the regulated emissions trading system. ESRS E1-6.44.AR.39.a, b, c, d; ESRS E1-6.48.b, AR.44.a Both the location-based and the market-based method are used to calculate Scope 2 GHG emissions. Traction current and three-phase current, which are used both in the areas of mobility and buildings in Austria, are 100% derived from renewable energies. Around 60% of traction current comes from self-supply (self-generation and generation by long-term partners). The remainder (40%) is purchased on the power market and backed by Guarantees of Origin. 100% of the three-phase current in Austria is purchased on the power market and is also backed by Guarantees of Origin.
