A major aspect in inventory routing problems (IRP) is the CO2 emissions from vehicles and its impact on the environment. Vehicle emissions depend on various factors such as vehicle’s weight, traveling speed, etc. This chapter presents the Pollution-Inventory Routing Problem with perishable goods (PPIRP), which is an extension of the Inventory Routing Problem with perishable goods (PIRP) that account not just for the transportation and inventory costs, but also for the cost due to greenhouse emissions. We develop a mathematical model for the PPIRP and solve it using GAMS. Through extensive computational experiments, we evaluate the impact of vehicle emissions on the results and find that our model achieves approximately 61 % reduction in carbon emissions and a 23 % decrease in empty vehicle trips compared to PIRP model. The objective of this chapter is to shed light on the trade-off between emission costs and total costs, and make the model more environmental friendly with a potential for pareto-improvements.
