Due to this, 95% of transportation operations are done by truck and, specifically in this case, distances can vary from 25 km to more than 1000 km. Besides the well-known restraints associated to road transportation (moderated velocity, high maintenance costs and limitations of volume and weight for the loads), 100 t of material transported for 1 km by truck is responsible for the emission of 13.7 kg of CO2 equivalent, besides the consumption of 5.27 kg of oil equivalent
