Annual Report 2025 – ÖBB-Infrastruktur AG

ÖBB-Infrastruktur Aktiengesellschaft Group Management Report | Consolidated Financial Statements 65 Target Reduction of Scope 3 greenhouse gas emissions in the rail infrastructure non-current asset sector by 10% by 2030 with the same volume of assets constructed as in 2022 Reduction in GHG emissions Economic activity EU Taxonomy Status Target scope The scope of the target relates to the upstream Scope 3 greenhouse gas emissions generated during the construction and maintenance of rail infrastructure. The greenhouse gases envisaged under the GHG Protocol are considered. in implementation phase Methodology To identify the key levers and derive the targets, the mass balances and greenhouse gas emissions for the base year 2022 were analysed in detail. Based on this, an ambitious target was developed together with technical experts. The target covers 29% of the ÖBB-Infrastruktur Group’s Scope 3 greenhouse gas emissions in the base year, which also addresses the relevant materiality in relation to the construction and maintenance of railway infrastructure. The basis for the development of the target is the same mass balances and greenhouse gas emission assessments as the greenhouse gas footprint (see category 3.2), which is why there is consistency with the greenhouse gas inventory and the scope. The GHG reduction target was calculated by allocating the sectoral transition paths of cement and steel according to SBTi to the quantities used by the ÖBB- Infrastruktur Group. The cross-sectoral transition path of -42% by 2030 was applied to the remaining investments. This results in a reduction of 28% compared to 2022 as the ÖBB-Infrastruktur Group company-specific decarbonisation pathway to meet the 1.5 degree target of the Paris Climate Agreement. The -10% reduction target represents a technically and economically feasible, ambitious reduction pathway that was developed taking into account as many factors as possible, but does not conform to the Paris Climate Agreement and the 1.5-degree target. The target described here is part of the transition plan from s ub-section E1-1 . The target was based on developments in the 1.5 degree climate scenario and the International Energy Agency’s net zero emissions scenario. The targets take into account forecast developments in the relevant value chains, risks of price increases due to alternative procurement and the planned expansion volume of the mobility transition framework plan. Due to the high technical requirements in the rail sector, also from a safety perspective, the identification of alternatives was limited to approved variants that are already permitted by standardisation. As construction activities and the materials used are the main drivers of GHG emissions, both greenhouse gas emissions and target achievement depend on the project volume realised and the respective trades with reduction potential in the target year. The target was evaluated by an external consultancy service in order to ensure a realistic depiction. The target is based on the identified decarbonisation levers in the rail steel, reinforcing steel and concrete sectors, which are described in more detail in the section on the climate transition plan (see sub-section E1-1 ). The base year 2022 is the first representative year after the COVID-19 pandemic, in which the construction activities carried out were also representative, and was therefore chosen as the starting year. Measure Decarbonisation levers The measures relating to the identified levers in the areas of concrete, rail and reinforcing steel comprise a number of individual measures. As a key step, comprehensive market studies will be carried out for all identified opportunities to assess availability and additional costs. Subsequently, projects will be identified in which the first applications of low-emission concrete will be implemented. Internal guidelines for the continued procurement of low-carbon concrete in precast elements and in construction will then be established and implemented. In addition, opportunities for sustainability and their potential implementation are assessed within the procurement process. approx. 25,000 t CO 2 e CCM/CCA 6.14. in implementation phase
