We are sustainable

Excellent public transport service is one of the key factors behind Vienna's status as the most liveable city in the world

For many years, Vienna has been recognised as one of the most liveable cities in the world. The excellent public transport system plays a major part in this, as the underground, bus and tram get people to their destinations quickly and safely. At the same time, every public transport passenger makes a significant contribution to climate protection, as public transport is environmentally friendly and sustainable.

Why is that? Public transport makes much better use of the available space in the city and transports more people than cars. And that means that every public transport passenger makes an active contribution to climate protection and to the high quality of life in our beautiful city.

Our sustainability in figures:


  • 900
    people
    fit into a single Vienna underground train. They would need 790 cars to reach their destination.

  • 300
    million
    additional passengers per year can travel by public transport thanks to the U2xU5 public transport expansion.

  • 30000
    jobs
    will be created and secured by the investment in the U2xU5 public transport expansion.

  • 1
    %
    is the share of public transport in the ecological footprint of the city of Vienna. The reason: the high efficiency of public transport.

  • 550000000
    car kilometres per year
    can be saved through the U2xU5 public transport expansion. That corresponds to the distance from Earth to Mars.

  • 4
    new underground junctions
    are being created by the U2xU5 public transport expansion. This will make public transport in Vienna even faster.

  • 100
    %
    of the electricity for our trams, underground trains and electric buses comes from renewable energy sources.

  • 80
    %
    of public transport passengers already travel in an environmentally friendly electric mode, as underground trains, trams and e-buses are powered by green electricity.

  • 2
    million
    passengers use public transport in Vienna every day. Together we are Vienna's largest carpool!
