Rail is the most sustainable mode of transit. For every passenger-km shifted from road to rail transport, 70% of the emitted CO2 would be avoided. As the global leader in rail technology, we view it as our corporate responsibility to maximize the environmental benefits of rail travel. That's why we have put sustainable mobility at the heart of our design, engineering and operating philosophy.Rail is the most sustainable mode of transit.
