CO2 Calculator - Emissions from Trains
Online CO 2 calculator for travel by train
By filling in the required information, the calculator below can be used to estimate the CO 2 emissions from your travels by train.
Additionally, it compares with emissions from alternative ways of travel.
How far do you travel?
Kilometer Miles
How is the utilization of train capasity?
% filled up (for trains, typical average filling degree is between 30 and 55%)
Choose the actual energy source of your train (definitions are given below) :
Diesel Low CO 2 el Medium CO 2 el High CO 2 el

Unit converter for conversion to and from non-SI units.
A few words about the assumptions for the calculator:
- The CO 2 emissions are strongly dependent on the energy source of the trains. We have used four different classes:
Diesel: No electric power
Low CO 2 el: Mainly non-emission electric power (hydroelectric, sun, wind etc)
Medium CO 2 el: An even blend of non-emission electric power and power from power plants fired with hydrocarbons (gass, oil or coal)
High CO 2 el: Mainly power from hydrocarbon fired power plants
- In comparison with alternative ways of travel, the efficiency regard to distance is set to be:
Train: 1 (reference)
Bus: 0.95 km/km train
Car: 0.92 km/km train
Plane: 0.75 km/km train
(The difference is due to more straight driving lines for cars and planes)
- Electrical cars are assumed to have the same electricity source as the trains on electrical power. Diesel trains are compared with electrical cars using Medium CO 2 el.
