ÖBB Annual Report 2025

89 Group Management Report Österreichische Bundesbahnen-Holding Aktiengesellschaft Consolidated Financial Statements | Group Management Report 46 Valuation methodology and thresholds for impact materiality and financial materiality 1) Impact materiality Financial materiality Subject of the assessment Impacts (negative / positive, actual / potential) of the ÖBB Group on people, the environment and the surrounding area Financial impacts on the ÖBB Group that may result from impacts or dependencies (external causes over which the Group primarily has no influence but which may affect the corporate group as opportunities or risks). Evaluation criteria Magnitude, scope, remediability, probability of occurrence Financial magnitude, probability of occurrence Rating scale 2) 4-stage (1 – little / low, 4 – very high) For potential impacts, a probability of occurrence scale of 1 to 3 was selected 4-stage (1 – little / low, 4 – very high) Scales correspond to the risk matrix of the ÖBB Group Time horizons Short-term – reporting year Medium-term – 1 to 5 years Long-term >5 years Short-term – reporting year Medium-term – 1 to 5 years Long-term >5 years Weighting of the criteria and calculation Different weighting Magnitude and scope are weighted equally, as impacts may be widespread while also being severe at a local level. Remediability is assigned a lower weighting, as it is often complementary to magnitude. An excessively high weighting of remediability could lead to minor but irreversible impacts being overemphasized. All three criteria are then multiplied by the probability of occurrence According to ESRS 1 (point 45), the severity of potential negative impacts is to be given priority over the probability of occurrence. To ensure this, an additional control was introduced in the process. Equal weighting Potential magnitude multiplied by probability of occurrence. Risks and opportunities are recorded from a gross perspective. Only those risks and opportunities that continue to exist after actions have been taken are recorded in risk management. Limit value 3) 2.5 4) 8 5) 1) ESRS 2.IRO-1.53.b.iv ; ESRS 2.IRO-1.53.c.ii .; ESRS 2. IRO-2.59. 2) Measurement scales slightly refined compared to the prior year; the calculation of financial materiality was more closely aligned with the risk management evaluation logic. 3) All impacts above this value are considered material. Once an impact, risk or opportunity within a (sub-)topic is material, the entire sustainability topic is to be considered material. 4) As all criteria are classified on a scale of 1 to 4, the threshold was selected as above the midpoint, i.e. higher than 2. 5) The threshold is set more narrowly than in risk management, as the double materiality analysis considers risks and opportunities on a gross basis and deliberately focuses on the most material risks and opportunities. Process for updating the 2025 dual materiality analysis ESRS 2.IRO-1.53.a, d A double materiality analysis in accordance with ESRS was carried out for the ÖBB Group for the first time in 2024. This was carried out in close collaboration between sustainability coordinators and representatives of all sub-group companies, technical experts, as well as the responsible risk managers and the responsible Management Board members. The identification and measurement of impacts, risks and opportunities was carried out using a combination of bottom-up and top-down approaches. It has become evident that the identified risks and opportunities do not necessarily arise solely from impacts; they may also increasingly result from dependencies. ESRS 2.IRO-1.53.c.i. To this end, all internally and externally relevant legal and regulatory frameworks of the ÖBB Group were taken into account and existing documents and records were reviewed. These include, for example, the Waste Management Act and requirements for achieving climate targets. In order to obtain as comprehensive a picture as possible of all business activities and relationships and the associated material impacts, risks and opportunities, a comparison is made with the contents of the EU Taxonomy Regulation (relevant economic activities for the ÖBB Group). No specific activities, business relationships or geographical circumstances were identified that lead to particular adverse effects. ESRS 2.IRO-1.53.b, g MR46 |
