Life cycle sustainability and eco-efficiency for mass transportation in Bangkok
Abstract:
Bangkok, the capital of Thailand, is currently facing a traffic congestion issue, which is caused by private and public vehicle accumulation like the other enormous cities around the world. To achieve sustainable policy and action plans together with increased cost-effectiveness for the transportation sector, public transportation was proposed. This study aims to evaluate the sustainability of public transportation in Bangkok by using the Lifecycle Sustainability Assessment (LCSA) and Eco-efficiency concept. The public buses and rapid transit, which operated by BMTA and MRTA were selected as a case study due to the highest public utilization rates. The LCSA using three evaluation tools i.e., Life Cycle Assessment (LCA) based on ISO14040, Life Cycle Costing (LCC), and Social Life Cycle Assessment (S-LCA) based on UNEP/SETAC2012, were used to assess the impacts that occur during the life cycle service system from environmental, economic, and social perspectives respectively. The final LCSA results were integrated into monetary value to represent the impact of all aspects. The environmental impacts were changed into an environmental burden cost. While economic impacts were directly used. The social impacts were evaluated as a social-problem solving cost. The LCSA results indicated that the highest impact came from the economic aspect around 8 and 16 billion baht, which are 91 and 80 percent for BMTA and MRTA respectively. The total impact cost of BMTA and MRTA were 0.4 and 0.06 THB/pkm respectively. Then the Eco-efficiency concept was applied to obtain the sustainable indicator by using service system value divided by total cost from all impact. The sustainable indicator of BMTA is far better than MRTA due to the yearly tremendous depreciation cost from railway infrastructure and the low utilization rate of MRTA which made the service value in terms of the total number and average kilometer traveling of passengers were low. The study shows the sustainable indicator concept that included the impact of environmental, economic, and social perspectives and also provides a conclusion and recommendation to enhance the sustainability of public transport in the urban area. The public transportation sustainable efficiency can use as the indicator for tracking service system and compare sustainability with other public transportation on both local and global scale.
