SJ purchases 100 % renewable electricity from hydropower, of which 50 % also carries the Good Environmental Choice label, which places more stringent environmental requirements on the generation of electricity. Our journeys have carried the Good Environmental Choice label for over 25 years.
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 on calculating transport emissions, such as EN 16258 or the Greenhouse Gas Protocol.
Enery consumption, train:
0.0081 kWh/passenger-kilometre. The figure is an average of all SJ's train types at average occupancy.
0.050 kWh/passenger-kilometre. This figure is for an X 2000 train at average occupancy.

Carbon dioxide emissions from the generation of hydropower electricity:
0.048 grams of CO2/kWh. This figure includes losses in the public grid and in the rail network.

0.081*0.048 = 0.0039 gram CO2/passenger-kilometre with average SJ train.
0.050*0.048 = 0.0024 gram CO2/passenger-kilometre with X 2000 train.
Carbon dioxide emissons, flight:
95 g CO2/passenger-kilometre.
