Air pollution control

We use modern vehicles to meet our customers' needs. And because they are less polluting and generate produce lower CO₂ emissions, they also benefit the environment. Let us introduce you to our vehicle fleets.

Our vehicle fleets: organized by standard

Rail vehicles and buses have a long service life, which means we aren't able to replace them as quickly as trucks and cars. We strive to use existing vehicles as long as possible and to extend their service life, particularly in light of dwindling resources.

We want to keep polluting emissions to a minimum since pollution can pose a health risk to people. But before we can take action, we need to know where emissions come from. That's why we document pollution broken down by mode of transport.

Pollution information

Pollution from particulate, carbon dioxide, sulfur oxide and nitrogen oxide emissions listed here has different effects. Particulate emissions, like nitrogen oxides, can cause respiratory diseases. Nitrogen oxides are also responsible for summer smog. Sulphur oxide causes acid rain, and carbon dioxide can cause allergies and other negative effects.
