Our commitment to energy sufficiency

Green driving and parking techniques, sustainable buildings, and solar panels are just some of the ways we’re cutting our energy consumption in response to the global energy crisis. The aim is energy sufficiency, sometimes called energy sobriety—meeting energy needs without excess.

An ambitious goal

As one of France’s biggest energy consumers, SNCF has been committed to responsible energy consumption for years. Our goal? Cut our energy consumption by 10% by the end of 2024.

  • 7%

    less energy consumption one year after the launch of our energy sufficiency plan

  • Equal to

    of our end-2024 target

  • Which is a

    10%

    reduction in Group energy consumption

Environmental benefits, economic benefits

There are so many reasons to lower our energy consumption:

  • reducing our greenhouse gas emissions
  • doing our part in French efforts to manage energy supplies
  • lowering SNCF Group’s financial costs

Easing our climate impact

We have pledged to significantly shrink our greenhouse gas emissions by 2030:

  • lowering transport activity emissions by 30%
  • lowering building emissions by 50%

Breaking down our consumption

SNCF consumes an average of 9,000 GWh of electricity per year. That comes from rail traction, buildings and road service vehicles—all areas where we can pursue energy sufficiency.

  • 82%

    of our energy consumption drives our trains

  • 15%

    powers our buildings

  • 3%

    fuels our service vehicles

More energy-efficient trains

The keys to our strategy are:

  • wider adoption of green driving, with drivers fine-tuning train speeds
  • green parking, which means shutting off engines as soon as possible to avoid wasteful idling
  • new technologies to make traction more efficient, including those used on the TGV M

And… Action! – Green driving and parking techniques

  • Green driving led to a

    5%

    drop in trains’ energy consumption in 2023

  • Green parking led to a

    16%

    drop in energy consumption

  • That amounts to a

    6.6%

    reduction in total energy consumption for traction in 2023

Testing new technologies

We’re testing innovative technologies to reduce the rail network’s energy consumption:

  • on lightly travelled lines, our automated start-and-stop system disconnects electrical substations when trains aren’t running
  • at Paris-Montparnasse station, we’re installing superconducting wires that are more efficient than copper wires, are 100% recyclable, and conduct high voltage electricity without any loss.

More energy-efficient buildings

We’re building more sustainable buildings, upgrading their insulation, and fine-tuning heating and cooling systems so they use less energy.

And… Action ! – Let there be light

  • 19°

    highest allowed temperature setting in winter

  • 26°

    lowest allowed temperature setting in summer

  • 7%

    savings on energy costs for each 1-degree cut in heating or cooling

We’re opting for green energy

  • by replacing light bulbs with LEDs, which lowers electricity usage 30% to 60% depending on the building
  • eliminating oil-fired boilers by 2025
  • installing more than 1 million m² of solar panels in our stations by 2030 and creating solar farms on SNCF land

And… Action ! – Our stations go solar

  • 6,5%

    reduction in buildings’ electricity consumption in winter 2022/23

  • 25%

    less natural gas consumed during the same period

  • 10%

    energy savings in 2023 across our property portfolio

What about SNCF Renouvelables?

We launched a new subsidiary in 2023, SNCF Renouvelables, to install solar arrays on available land and building rooftops. Our goal is to generate 20% of the energy we consume by 2030. By 2050, we want to be energy-independent.

Freight trains use less energy than trucks

Fun fact: One freight train can haul as much cargo as 40 lorries.

Not only that, but each tonne of freight transported by Fret SNCF:

  • requires 6 times less Energy
  • and emits 14 times less pollution

And… Action ! – Freight’s environmental advantages

Changing behaviour

We’re adopting better habits to limit power usage by office IT workstations, employee PCs and tablets, and our datacentre servers.

That means:

  • extending the life of our IT Equipment
  • doing the small things, like remembering to turn off personal and company devices when not in use
  • shrinking the amount of data individuals use—our Mon e-Carbone app calculates carbon emissions related to digital equipment and cleans up large, obsolete or duplicate emails
