The need to reduce the environmental effects related to the traffic of trucks used for the transport of marble from the quarries to the processing plants, has led us to make assessments on the methodology to be applied. This paper presents the methodological approach identified to determine the best technical solution among several alternatives regarding the transport of marble. The validation of the methodology has its natural outlet in the application of a real case
