A Study on the Metro Logistics for Reduction of Greenhouse Gas and Social Logistics Cost Using the Modal Shift

Abstract

After the Kyoto Protocol was negotiated, reducing greenhouse gases (GHGs) emissions has become a global issue and challenge to most of countries in the world. Korea belongs to non-Annex B parties without binding targets, but has been devoting a lot of effort into low-carbon policies and reduction of GHGs emissions to cope with predictable future demand. Based on the concept of modal shift, this paper proposes a logistics system using underground (railway) trains and the route network as part of eco-friendly green logistics to reduce GHGs emissions in the transportation sector. The proposed system also is to reduce logistics and road transport-induced social costs. Computational results show that GHGs emissions as well as overall travel distance are reduced and as a result, logistics and social costs are saved significantly.
