Green Logistics is an approach that aims to minimize costs by incorporating economic and environmental
objectives into the traditional goals of distribution management. Studies on Green Logistics address topics such
as the use of electric vehicles, renewable energy, shared vehicle usage, intelligent transportation systems, fuel
efficiency, low-emission vehicles, and route optimization. Considering that transportation constitutes a major
part of logistics, environmentally sensitive logistics policies can lead to a sustainable distribution network with
fewer negative impacts on the environment and ecology by changing the transportation network. In this context,
the type of problem addressed in vehicle routing studies is called the 'Green Vehicle Routing Problem (GVRP).
Since it is known that a significant portion of CO2 emissions originates from transportation, one of the solutions
approaches to GVRP is the minimization of the carbon footprint. Various approaches are used in calculating the
carbon footprint, with the Tier-1 method being the most general and widely used.
This study addresses a bi-objective GVRP that aims to minimize both the total distance and the carbon footprint
of the route. An application conducted on student shuttle services determined the shortest routes that also
minimize the carbon footprint for these school services. According to the study's findings, the new routes can
result in an 11% reduction in carbon footprint.
