Tool 
NTMCalc was created by Nätverket för Godstransporter och Miljö (NTM, the Network for Freight Transport and the Environment). 

Purpose 
Calculate the emissions and energy consumption for a user defined transport chain. Users would be anyone interested in environmental performance of their transports. The tool could be used for optimizing transports by evaluating different transport strategies. 

Description 
The user defines a transport chain e.g. train, Götebog-Västerås, lorry Västerås-Sala,... and enters the weight of what is transported and data on the efficiency of the transport (fuel consumption, load factor,...). Result is presented as a table of emissions and energy consumption for all steps in the transport chain and for the total. 

Description in Swedish

Use 
The tool is very simple to use
