Negative Short-term – Own business activities E1-A-8 Energy generation from renewable sources (hydropower, wind power, photovoltaics) increases independence from fossil fuels and conserves natural resources. Positive Short-term – Own business activities E1-F-9 Legal regulations and an uncertain global political environment (armed conflicts, etc.) lead to changes on the energy market. The cost of energy is rising. Risk Short-term E1-F-10 The upgrade of in-house production reduces dependence on external energy providers and fluctuating electricity prices. This can reduce costs. Opportunity Short-term 1) Material impacts are to be regarded as real unless explicit reference is made to the contrary. ESRS 2.SBM-3.48.c. 2) The update of the double materiality analysis has led to minor adjustments (type of impact or risk/opportunity, time horizon and information on the value chain) compared to the prior year. ESRS 2.SBM-3.48.g. 3) ESRS 2.SBM-3.48.c. Climate-related physical risks – The measurement of risks related to natural hazards has been part of the risk management system for years. In view of increasing extreme weather events, the long-term analysis of climate risks is gaining importance. Accordingly, a climate risk and vulnerability analysis was conducted for the ÖBB Group for the first time in 2022 (including relevant companies and assessment objects). The entire process was accompanied by GeoSphere Austria. Physical climate risks were considered for short-term (reporting year), medium-term (up to 2030) and long-term (up to 2050) horizons, based on ÖKS15 data and the RCP 8.5. climate scenario. ESRS E1.IRO-1.AR.11.a, b – Initially, non-applicable climate hazards were excluded in accordance with EU Regulation 2021 / 2139. The remaining risks were assessed in terms of potential impairment of economic activities and assets. Among other things, buildings, rolling stock, railway network and personnel were analyzed, as well as multi-hazard impact chains. The measurement was carried out for the following ÖBB Group companies: ÖBB-Infrastruktur AG, ÖBB-Personenverkehr AG, Arverio Baden-Württemberg GmbH, Rail Cargo Group, ÖBB-Produktion GmbH and ÖBB-Technische Services-GmbH. Internal experts assessed the severity and probability of occurrence, taking into account site exposure and vulnerability. Potential risks result from the probability of occurrence multiplied by the impact. No quantitative measurement was carried out. ESRS E1.IRO-1.AR.11.c, d – The analysis showed that the severity of climate hazards varies depending on the time horizon. Apart from minor updates to sites across all ÖBB companies and further detailing of individual assessment objects, there were no significant changes. Various climate hazards such as heat waves, wind, river flooding, coastal flooding, changes in precipitation, and extreme precipitation were taken into account. The new climate data (ÖKS26) is expected to require a significantly expanded revision of the climate risk and vulnerability assessment in 2026. ESRS E1.IRO-1.20.b, 21 Climate-related transition risks and opportunities In the 2025 financial year, the analysis of climate-related transition risks and opportunities for the ÖBB Group was continued and further deepened. In a first step, the climate-related transition risks identified as part of the dual materiality analysis were assigned to the categories of political, legal, technological, market and reputational risks. They were then classified according to time horizons (short-term = reporting year; medium-term = up to 2030; long-term = up to 2050) and measured according to extent and probability of occurrence. The entire value chain was considered in the process. ESRS E1.IRO-1.20.c, AR.12.a For the qualitative assessment of potential risks, the “Transition” scenario of the Environment Agency Austria was used. The measurement of climate-related transition risks and opportunities based of their potential magnitude and probability of occurrence, taking into account the assumptions underlying the scenario. Two significant transition risks were identified. No assets or business activities were identified that are incompatible with a transition to a climate-neutral economy. The climate scenarios used are consistent with the climate-related assumptions in the financial statements, as a reconciliation of gross and net risks was performed.
