The use of certain chemical substances in some operational processes is unavoidable. However, SBB aims to reduce the use of dangerous substances as much as possible.
For example, it places greater emphasis on biodegradable and non-toxic cleaning products which still guarantee top-quality cleaning performance while also minimising environmental impact, such as in the case of graffiti removal. This not only reduces risks for staff, but also helps to conserve natural resources.
Another major step is the electrification of construction sites and fossil-fuel-driven traction vehicles. This reduces the use of diesel, which can be harmful to the environment and to health when handled and burnt.
