Environmental measures

• Since April 2023, as part of a pilot project, DB Regional has been using the climate-friendly biofuel HVO (hydrotreated vegetable oil) for vehicles on the Schwarzatalbahn line. This will save around 430 t of CO₂ over the pilot period.
• DB Regional has concluded a framework agreement with the Portuguese manufacturer Caetanobus for the supply of 60 hydrogen buses by 2026. The first vehicles will begin running in Lower Saxony and Schleswig-Holstein at the beginning of 2024.
• Since February 2023, 22 new battery-powered electric buses have been successfully operating in Schleswig-­Holstein, offering emissions-free mobility.
• In Berlin-Grünau, a new 160-meter-long washing facility with a water recycling system was put into operation. As a result, up to 90% of the water used there can be reused.
