Sustainability

Rail plays a crucial role in achieving the EU’s 2050 climate neutrality goal, primarily through a modal shift from polluting transport to rail. Although rail remains the lowest-impact mode of land transport, challenges such as energy consumption, noise, and environmental footprint remain, which we actively work to reduce.
