Travel climate-friendly with SJ

Choosing the train is an easy way to reduce your impact on the climate and the environment. 100 % of our electricity comes from hydropower, a reneable source. 50 % of which is also carries the Good Environmental Choice label ("Bra Miljöval"), shich places further requirements on the generation of electricity. SJ journeys have carried the Good Environmental Choice label since 1994, and the train is still the way of the future to travel.

See how climate-friendly your journeys are

As an SJ Prio member, you receive a regular report (in Swedish only) on how climate-friendly your travel has been and how much carbon dioxide you have saved compared with if you had travelled by car or aeroplane.

100 % renewable energy makes SJ's trains climate-friendly

SJ only purchases electricity from renewable sources, which is just one of the reasons why travelling with us is climate-friendly. All our electricity comes from wind and hydropower. 50 % of the electricity is also Good Environmental Choice labelled ("Bra Miljöval"), which places further requirements on the generation of electricity, such as not drying out riverbeds and building fish passages for fish and waterborne species.

Travelling by train is energy-efficient

On a train, there are many of us travelling together. This makes the energy-efficiency per person of a train journey extremely high. The train is also powered by electric motors, which are highly efficient compared with gasoline and diesel engines. The electric motor uses more of the energy with less of it going to waste, in the form of heat for example, compared with petrol and diesel engines.

The long, narrow design of trains also means that there is less air resistance compared with a vehicle that is wider and shorter.

Organic food in the bistro on SJ's trains

Our bistro offers several organic alternatives, including dishes from the restaurant Kalf & Hansen. Kalf & Hansen focuses on ingredients that are in season when they compose their dishes and almost everything is locally produced.

In 2018, the partnership between SJ and Kalf & Hansen was named "Brilliant Idea of the Year" by the Fast Food Awards.

How long can a train freewheel for?

There are lots of routes in our oblong country where SJ’s train drivers let their trains freewheel; in other words the driver does not use the engines to drive the train forward. Freewheeling a train for 60 km is a piece of cake, according to many of our drivers! If the departure station is at a higher altitude than the arrival station, you can even freewheel for more than 100 km. Here are some of the routes where SJ’s train drivers let their trains run entirely under their own power, where circumstances allow:

  • Nässjö–Mjölby, 85 km
  • Malmsjön-Stockholm, 50 km
  • Falköping–Gothenburg, 180 km
  • Södertälje–Stockholm, 40 km
  • Vårgårda–Gothenburg, 70 km
  • Floby–Gothenburg, 100 km
  • Sösdala–Lund, 50 km
  • Nässjö–Alvesta, 80 km

Data sources:

Our calculations are based on the electricity we purchase, in other words, electricity from a renewable source (hydropower). This is in line with the international standards for calculating transport emissions, such as ISO 14083:2023 and the Greenhouse Gas Protocol.
