AbstractGreen Logistics has received considerable attention recently due to the interest in environment preservation which plays an important role in strategic and operational logistical activities. The vehicle routing problem (VRP), as part of logistics, is one of the most widely researched and has mainly focused on economic objectives, not considering explicitly environmental issues. Therefore, environmental issues are to be added to cost saving objectives, to find the right balance between these two dimensions. A multi-objective problem (MOP) model that simultaneously considers the internal costs and environmental issues can better describe the real logistics operations than a single objective model. This paper proposes an eco-efficient MOP model based on a realistic variant of the VRP with time windows constraints and a heterogeneous fixed vehicle fleet, in which vehicles are characterized by different capacities, costs and emission factors. Three objective functions are run to minimize the total internal costs, while minimize carbon dioxide (CO2) and nitrogen oxides (NOx) emissions. Finally, this paper presents a case of study to analyse the results of the choice of eco-efficiency routes which can help to reduce the emissions of air pollutants and greenhouse gases.
