Developing public transport to reduce energy impact

The Keolis Group, a sustainable mobility operator, has been committed to protecting the environment for 15 years
Old habits die hard. In France today, it is estimated that 80% of journeys to work involve a car containing just one occupant: the solo driver. All in all, car journeys account for 50% of transport energy consumption, whereas collective systems account for just ... 2% (source: ADEME). As Keolis Executive Chairman Jean-Pierre Farandou puts it: “When it comes to energy challenges, public transport is the solution, not the problem.” We need to remember that shared travel modes offer a solution to reducing direct emissions of greenhouse gases around the world.

The good news is that there are numerous public transport solutions that can be applied to reduce pollution, depending on the operations and renewable resources available in the countries concerned. Keolis uses eleven different types of energy to transport its 3 billion annual passengers. These include electricity, biodiesel (diesel fuel of vegetable origin), biogas, bioethanol and hybrid solutions. In Lyon, for example, 75% of the public transport service, whether it be metro, tram or trolleybus, runs on electricity.

In Lille, 100% of passenger journeys now use diesel alternatives: electricity for the metro and trams, and gas (some of it biogas) for city buses. In 2016, 5,500 Keolis vehicles across Europe will be equipped with an eco-driving system, providing a 4% reduction in fuel consumption. 

Leading by example

LThe Keolis Group has also been working for many years to improve its own environmental performance. Keolis has set itself three priorities in implementing its environmental policy:

  • optimise energy consumption
  • improve waste management
  • reduce consumption of drinking water for industrial use.

In Tours, for example, solar panels have been installed on the roof of the Tram Operations and Maintenance Centre. In Dijon, recycled water is used for washing vehicles. In Bordeaux, highly polluting solvent-based degreasing fountains have been replaced with eco-fountains, thereby reducing cleaning liquid waste by 5 tonnes. 

In Sweden, wind turbines are used to cover 38% of the annual energy consumption of Keolis Sverige.
