内容記述 |
In Asian developing countries, rapid motorization in mega cities could increase the amount of CO_2 emissions from passenger transport. One of counter policies to CO_2 mitigation is to promote low-carbon transport modes in urban area. But CO_2 emissions per passenger-km from passenger transport depend on the number of passengers carried. It is also important to consider throughout lifetime CO_2 emissions generated from production of infrastructure and vehicles as well as from their operation. This study proposes a method to identify low-carbon passenger transport modes for intra-urban travel by province-level region in Asian developing countries, using Life Cycle Assessment (LCA) approach. As intra-urban transport modes, the focus is on passenger car, Bus Rapid Transit (BRT), Light Rail Transit (LRT) and heavy rail. First, demand for use of each mode is estimated with the population density of the densely inhabited area of each province as transport density. Then, the number of operated vehicles to meet the demand is determined by transport density. Finally, Life Cycle CO_2 (LC-CO_2) emissions from infrastructure construction, vehicles manufacturing and operation are calculated by multiplying emission factors by the number of vehicles and their root length. The mode with the least LC-CO_2 is identified as a low-carbon transport mode for each province. As case study areas, this study analyses provinces in Thailand by using Thesaban nakhons as a densely inhabited area. In addition, as future technological scenarios for Asia are considered with emission factors of Japan. The main results of this study are as follows. (1) In a scenario with emission factors of present Japan, BRT emits the least LC-CO_2 in provinces with highly-dense urban areas and in the remaining provinces and, the introduction of mass transit mode cannot reduce CO_2 emissions. (2) In a scenario with emission factors of future Japan, passenger car is selected as a mode that emits the lowest CO_2 in most provinces. |
