Annual Report 2025 – ÖBB-Infrastruktur AG

ÖBB-Infrastruktur Aktiengesellschaft Group Management Report | Consolidated Financial Statements 84 Land use has been recognised as a major factor contributing to biodiversity loss and affecting the extent and condition of ecosystems. This is accompanied by temporary or permanent changes to the habitat resulting from the construction of transport infrastructure and associated systems and facilities. The assessment of land inventory of the ÖBB-Infrastruktur Group *) in km² 2025 2024 Change Change in % Total floor space 190.8 190.8 0.0 0% Managed net floor area of all buildings (including transport stations) 8.3 8.5 -0.2 -2% Net land floor space of the buildings (without traffic stations) 2.5 2.6 -0.1 -4% Other open spaces (gardens, meadows and embankments etc.) 6.5 6.7 -0.2 -3% Park & Ride facilities 1.4 1.3 0.1 8% *) Company-specific information in conjunction with impact E4-A-1. The ÖBB-Infrastruktur Group is required by railway regulations to keep the track system as free of vegetation as possible in order to ensure safe railway operations. In order to minimise negative environmental impacts, only vegetation that is actually present is treated using green detection technology. Research is also being conducted into non-chemical methods of weed control. Key figures relating to chemical vegetation control 1) 2025 2024 Change Change in % Amount of active substances used per year in kg 2) 7,113.0 1,288.0 5,825.0 452% Kilometres of track controlled for vegetation 9,155.0 8,020.0 1,135.0 14% Area controlled for vegetation in hectares 6,277.0 5,496.0 781.0 14% Treated proportion of controlled areas in % 31.0 30.0 1.0 3% 1) Company-specific information in conjunction with impact E4-A-2. 2) In 2025, the new active ingredient pelargonic acid was introduced. This is characterised by its very rapid biodegradability. As the herbicide acts purely by contact with the plants, significantly higher application rates are required for treatment compared with systemic herbicides. E5 Resource use and circular economy E5 Overview The following is an overview of the main impacts, risks and opportunities. No. Material IRO 1) 2) Type of impact or Risk / opportunit y Time horizon Information about the value chain for impacts Sub-topic: Resource inputs, including resource use E5-A-1 Significant extraction of finite resources occurs due to the resource intensity of the construction sector, both in maintenance and in new construction projects along the value chain. Negative Short – Own business activity – Upstream value chain E5-F-1 Consideration of circular economy aspects and the use of secondary raw material sources have a positive effect on cash flows. Opportunity Medium Sub-topic: Waste E5-A-2 Waste generated by construction activities requires further treatment (recycling processes) to make resources reusable and may result in material loss. Negative Short – Own business activity – Downstream value chain 1) Material impacts are to be considered actual unless explicitly stated otherwise. 2) There have been no changes to the existing impacts, risks and opportunities since the previous reporting period.
