We propose a Genetic Algorithm (GA) to address a Green Vehicle Routing Problem (G-VRP). Unlike classic formulations of the VRP, this study aims to minimise the CO 2 emissions per route. The G-VRP is of interest to policy makers who wish to reduce greenhouse gas emissions. The example shows how to add route zones associated with the routes in a vehicle routing problem. The two routes in the input vehicle routing problem are operated by vans that are only licensed to service orders in a predetermined area and so cannot service orders that are outside of the route zone.
