Transport is a priority issue for a sustainable development. Freight transportation is a key component of all the supply chain and logistics systems. In EU27, 31,030 persons were killed in road incident in 2010 (EU, 2012); urban outdoor air pollution is estimate to cause 1.3 million deaths worldwide per year (WHO, 2011); transport is responsible for around a quarter of EU greenhouse gas emission (EU, 2011); many people are exposed to high transport noise levels that affect their quality of life and health. These are examples of external costs generated by transport users but not paid by them. In the attempt to reduce the environmental costs of transport, EU public decision makers recognised the need to charge the external costs according to a ‘user pays’ and ‘polluter pays’ principle to drive supply chain decision makers towards sustainable choices. In order to achieve EU targets, more severe public regulations will be adopted in the near future in EU Countries. Traditional inventory models minimise logistics costs neglecting externalities. The aim of this paper is to evaluate the benefits of the internalisation of the external costs in a classical logistic problem, the inventory management problem. In order to do this, in this paper the sustainable order quantity model (Digiesi et al., 2012) has been adopted. The model allows identifying (in case of a deterministic product demand and lead time) the optimal lot-size and transportation mean which minimise logistic costs (holding, ordering and transport), as well as external costs of transport. Finally, a sensitivity analysis has been performed in order to investigate the effects of different internalisation strategies of external costs on the solution of the inventory problem. In order to evaluate the effectiveness of the proposed strategies, they have been tested on a real case study.
