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.
Energy consumption and carbon dioxide emissions, train:
0.073 kWh/passenger-kilometre. The figure is an average of all SJ's train types at average occupancy.
0.061 kWh/passenger-kilometre. This figure is for an X 2000 train at average occupancy.
0.104 kWh/passenger-kilometre. This figure is for an SJ EuroNight train at average occupancy.
