Long-term business success requires clear objectives, transparent measures and regular review. That is why ÖBB has strategically embedded its sustainability goals, defined measures and reports key Group figures transparently in its Non-Financial Statement.
In its day-to-day operations, as well as in projects and partnerships, ÖBB is working to develop mobility and logistics step by step and to reduce emissions within its own sphere of influence. The focus here is on environmental, economic and social aspects. In 2025, 559 million passengers and around 79 million tonnes of freight were transported.
Further highlights:
- The electricity for the rail network, as well as for ÖBB buildings and operational facilities in Austria, comes from 100 per cent renewable energy sources. Around 60 per cent of the traction power for the rail network is sourced from in-house supply (in-house generation and generation by long-term partners). The remainder (around 40 per cent) is purchased on the electricity market and backed by guarantees of origin. 100 per cent of the three-phase current in Austria is purchased on the electricity market and is also backed by guarantees of origin. 77% of Austria’s railway lines are electrified, and at least 90% of passenger trains operating on the ÖBB network run on electricity.
- With the 2027–2032 framework plan, we are continuing our investment strategy in a modern, high-performance and reliable rail network for the future. Investments totalling 19.5 billion euros are planned for this purpose. Find out more here.
- Across the Group, more than 48,000 bus and rail staff – including 2,145 apprentices – ensure that more than 1.5 million passengers reach their destinations every day.
- A train journey on the ÖBB in Austria produces more than 30 times fewer CO₂ emissions per passagner-kilometre than a typical passenger car. For short-haul flights, the figure is at least 50.*¹
- The Postbus produces around three times less CO₂ per passenger-kilometre than a typical passenger car.*¹
- ÖBB’s railway freight transport in Austria produces more than 20 times less CO₂ per tonne-kilometre than road freight transport.*¹
- Our rail and bus transport services save more than 4 million tonnes of CO₂eq annually in Austria compared with providing the same transport services using passenger cars and trucks.*²

Details of the calculation methodology behind our highlights:
To calculate the comparative figures between ÖBB’s transport services (passenger and rail freight transport, as well as passenger transport by Postbus in Austria) and the modes of transport – passenger cars, aeroplanes and trucks – the specific greenhouse gas emissions per passenger-kilometre or tonne-kilometre (g CO₂eq/pkm or tkm) are used.
The comparative figures for passenger cars, air travel and trucks are taken from the emissions data published by the Environment Agency Austria (UBA). Only the sum of direct emissions and upstream greenhouse gas emissions from fuel production and electricity generation is taken into account; vehicle manufacturing is excluded. The comparative figures are calculated on the basis of grams of CO₂ equivalents per g CO₂eq/pkm or g CO₂eq/tkm.
The emission figures for ÖBB’s transport services (passenger and rail freight transport, as well as passenger transport by Postbus in Austria) are based on UBA-verified ÖBB data, which can be found here in the ÖBB Annual Report (Sustainability Report section).
*¹: Data source: Environment Agency Austria (UBA), 2024 emissions figures for modes of transport: For average passenger cars: 174 g CO2eq/pkm, flights <1,000 km: 261 g CO2eq/pkm, for average trucks: 75.3 g CO2eq/tkm, as well as ÖBB data from 2024 verified by the UBA for rail passenger transport: 4.66 g CO2eq/pkm, Postbus passenger transport: 55.1 g CO2eq/passenger-km, rail freight transport in Austria: 3.11 g CO2eq/tonne-km
*²: Data source: All ÖBB transport services in Austria relating to passenger transport by rail and road, as well as rail freight transport in 2025 | Rail: 12,672,308,257 pkm, Postbus: 2,632,000,000 pkm, rail freight: 12,410,449,198 tkm (net tonnes). The figures used for this purely mathematical comparison are based on the emission figures (2023) from the Environment Agency Austria for passenger car and rail freight transport: Ø passenger cars: 225.6 g CO2eq/pkm, Ø trucks: 65.2 g CO2eq/tkm
