The emission of CO 2 by the belts was calculated according to the emission factor of the National Integration System considering the base year of 2014 . In order to determine the emission of CO 2 by the combustion of diesel in both belt conveyor and truck systems, the CO 2 emission factor for heavy diesel equipment was used [ 27 ].
