Worldwide climate change conventions have begun promoting at the global lever as a result of global warming issues due to the rise in energy consumption. Energy consumption in our domestic transportation section alone has risen 43.4% over the past 22 years. This has allowed for the ``Allocation of CO2 Emission and Trade`` to come into effect starting January 1st of 2015, which imposes an adequate carbon tax to a business if CO2 emission exceeds the standard amount. Therefore, reduction of greenhouse gas emission has become an important aspect to all business industries. Most domestic delivery services for large-sized consumer electronics include delivery and installation of a product. Currently large-sized appliances are being delivered by separate vehicle while same-day delivery service is practiced in response to faster delivery requests made by consumers after purchase. Unfortunately, however, the same-day delivery principle for small and medium-sized appliance is inefficient in comparison to large-size electronics due to the limited amount of product load being transported by a same-sized transportation vehicle. Therefore, negatively effecting both the logistics cost and greenhouse gas emission. This study was to analyze the possibility of reducing greenhouse gas emissions according to the vehicle dispatching method and vehicle routing decision policies for the delivery of sold consumer electronics. In order to reflect the current delivery environment, actual data from the K logistics company were referenced while the research environment parameter was divided into urban and non-urban areas. The vehicle dispatching method was tested and performed using two 2.5 ton trucks for daily delivery and one 2.5 ton truck for deliveries made every other day. The Sweep and Genetics algorithms were applied at the VRP (Vehicle Routing Problem) environments for the vehicle routing decision policies. Proposed alternative shipping methods to reduce greenhouse gas emissions were proposed via comparative analysis of the emission volume caused by conventional delivery methods to targeted urban and non-urban areas.
