Transportation represents a ratio between 30 % and 70 % of total logistic costs, plus a direct impact on client´s satisfaction. It is also a considerable source of CO 2 emissions, thus affecting the environment. Objective. Design and validate a model for green transportation management, increasing the process´ efficiency, reducing CO2 emissions and implementing environmentally friendly green practices in this logistic process. materials and methods. The Green transportation model integrates a management component (objectives, strategy and characterization), information and communication technologies (ICT) and a mathematical modeling of the routing problem that considers a fleet of heterogeneous trucks, solved by the use of a metaheuristic. Results. In the validation in a meat company the solution to the routing problem was achieved by means of a genetic algorithm, through which the process´ efficiency increased up to a ratio between 9,89 and 12, 86 %, reducing transportation time in the routes in 4410 minutes a month if compared to the routing rule the company had before. With a green model, a reduction of 2791 kg of CO 2, equivalent to 11,70 % of the current emissions generated by transportation there, was achieved. This way, we can have a quantitative assessment of the contribution the green transportation management model makes to this research area, to the efficiency of the process and to environmentally friendly practices.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráTecnologías de la Información y la Comunicación (TIC)LogísticaGases de efecto invernaderoTransporte de cargaProtección del medio ambienteArticle
