STIB is continuing to replace and expand its fleet.

Electric buses and hybrid buses are ever more numerous on the network. The shift towards innovative and more environmentally friendly technologies means that travelling by public transport is even more ecological. As such, STIB actively participates in the low emission zone set up by the Brussels Region.

Trams and metros are powered by electricity and as a result do not directly produce any polluting emissions. Furthermore, STIB procures its energy from a supplier which is asked to prove - through Guarantee of Origin certificates - that it produces or purchases renewable electricity in quantities equivalent to its consumption.
