This is the genral formula for calculating the CO2 emissions. We multply the co2 equivalents with the number of km traveld. Some of the transport mothods used tihis simple fromula, whilst others have small varibale changes. This will shown under. The co2 emissions for each transport method for one kilometer are presented in a table at the bottom of the page.

This is the foumal we use to calcucalte emissions for cars. We chose to give the variable w three possible values. A standard size vehicle is being attributed the value 1. We consider that an SUV, for a same distance, is responsible for 15% more CO2 emissions on average than the standard sized vehicle, which corresponds to the value of 1,15. Asmall sized vehicle, which on average emits 15% less CO2 than a standard sized vehicle is attributed the value of 0,85.

For the plane, train, bus and ferry we apply the same principle. Emission per kilometer multplied by the number of kilometers. For this shared methods, the number is for one passenger rather than the whole tour. We introduce also another formula which can be used to find the emmisions for all the passengers.

We intorduce one last formula, for calculating emmsions for takin teh ferry with a car.
