The need to reduce greenhouse emissions through changes in transportation operation is dire leading the industry to implement a variety of Green Logistic Practices (GLP). However, the freight industry to date still relies heavily on the use of fossil fuels. The question of fuel alternatives is present but passive in current research, thus opening the gap for further exploration into fossil-fuel alternatives. The purpose of this study is to summarize the research currently represented in published literature discussing green practice options in freight transport and logistics and to explore the use of fossil-free fuels. Focus on biomethane derives from its regional importance for the research group.
This study was completed in two parts. The literature review was completed in a systematic manner to ensure quality. The authors collected additional information through semi-structured, exploratory interviews from various stakeholders involved in research and general interest of switching to biomethane with a purpose of ensuring the practical relevance.
The literature review identifies patterns and trends among discussed GLPs. Practices utilized and researched include but are not limited to intermodal transport, platooning, and implementation of fossil-free fuels. Most of the practices researched involve limited new technology or innovation rather a repurposing of traditional techniques. While the revisiting and greenifying of traditional techniques aids in reducing the emission of greenhouse gases, freight transport and logistics lags in understanding of switching to fossil-free fuels.
