EcoTransIT World determines the emissions using an energy-based bottom-up approach. That means the emissions are determined on the basis of the energy consumed and the fuel used. This makes a big difference to the otherwise usual top-down approach, in which gCO2e / tkm are multiplied by the freight weight and a distance.
The bottom-up approach simulates the complete transport system. This ranges from the type of road, to the vehicle class with corresponding properties, to the fuel. This method makes EcoTransIT World future-proof, because in order to map new types of fuel or vehicle technologies, only one parameter needs to be adjusted in the calculation workflow.
This calculation workflow is structure as follows:
