The vehicle routing problem is an optimization problem in which the minimum cost set of routes is determined to deliver the orders to the customers. With the increase in environmental awareness in recent years, practitioners and researchers have started to focus on the environmental aspects of transportation activities to reduce the environmental impact of fossil fuels. The type of vehicle routing problem that takes this sensitivity into account is called the green vehicle routing problem. The green vehicle routing problem is a subject that has been studied extensively in recent years. The main motivation of the study is to develop an approach in order to minimize the emission gases resulting from the operation of load collection/distribution routes for heterogeneous vehicle fleets that are naturally encountered in daily life. In the study, the distribution activities of a company operating as a regional distributor were handled as a green vehicle routing problem with a heterogeneous fleet and environmental solutions that provide lower emission values were tried to be obtained by the simulated annealing method. In the solution approach, emission values for a heterogeneous fleet are calculated based on the amount of load carried by the vehicles and the distance the loads are transported. The green vehicle routing solutions were compared with the emission values calculated over the solutions obtained as the standard vehicle routing problem. As a result, due to the relationships between load amount, transport distance and emission, the proposed approach provided solutions with lower emission amount despite higher travel distance in some datasets. Considering the total value of all solutions, 38.5% better solutions in terms of travel distance and 86.7% better in terms of emission value are obtained.
