Annual Report 2025 – ÖBB-Infrastruktur AG

ÖBB-Infrastruktur Aktiengesellschaft Group Management Report | Consolidated Financial Statements 55 By way of the measures adopted in the #INFRAsustainabilitystrategy to reduce Scope 1 and Scope 2 greenhouse gas emissions, a reduction of approximately 42% by 2030 (compared to the base year 2022) is currently planned. Therefore, there is a greenhouse gas emission reduction target and a transition plan in line with the 1.5 degree target for the ÖBB-Infrastruktur Group for Scope 1 and 2 by 2030. The ÖBB-Infrastruktur Group is dependent on third-party solutions for both the procurement of district heating/cooling and the use of refrigerants. Refrigerants (for maintaining the operation of air conditioning systems) are used at ÖBB Infrastructure AG for cooling buildings (e.g. offices), for cooling technical rooms (telecommunications, control and safety technology etc.) and in tunnel structures. Due to the F-gas Regulation, refrigerants will be subject to increasingly stringent limits in the coming years. This will lead to a conversion of the systems and a reduction in GHG emissions, as well as increasing reinvestment costs. The decarbonisation of district heating depends on the plans of the suppliers; this transition scenario has also been included in the decarbonisation path. Additional measures are necessary by 2035 to reduce the remaining emissions to 90% (reduction target before offsetting) compared to the base year 2022. These will particularly affect the decarbonisation of the commercial vehicle fleet. Due to the difficult market situation, economic considerations or the technical requirements placed on the vehicles, there are currently very few vehicles with alternative drive systems available on the market that meet ÖBB’s operational needs, particularly in the commercial vehicle sector. However, the framework conditions and technical developments are subject to ongoing review. Due to the specific service life of commercial vehicles, it will still be possible to implement measures at a later date to achieve the targets. Scope 3 greenhouse gas emissions The levers for reducing Scope 3 greenhouse gas emissions for ÖBB-Infrastruktur Group result from the identified material impacts, risks and opportunities of the double materiality analysis (see s ub-section ESRS 2 – IRO 1 ). These relate to greenhouse gas emissions from construction and maintenance activities and fall into the Scope 3 categories “Procurement of capital goods” and “Purchased goods and services” (GHG Protocols 29 3.1 and 3.2). The main greenhouse gas emission drivers are steel and concrete and, to a lesser extent, aluminium, glass and copper. These therefore represent the decarbonisation levers and were determined on the basis of an analysis of the quantities used in the rail infrastructure sector. The following table and chart show the main decarbonisation levers in Scope 3 and their quantitative contribution to achieving the targets in accordance with the transition plan. Further information and related strategies can be found in s ub-section E1-2 . The most important targets and measures are explained in more detail in sub-sections E1-3 and E1-4 . 2 9 https://ghgprotocol.org/.
