Embodied Energy and CO2 Emissions Evaluation for Freight Transport

초록

This study aim at demonstrating the environmental performance of freight transport of the rail and road mode through an indicator of embodied energy and CO2 emissions. Using the concept of LCA, the scope of evaluation includes energy production, supply chain activity and operation. The results of embodied energy and CO2 emissions are normalized by means of traffic volume. The results shown that embodied CO2 emissions road mode is 607.07 gCO2-eq./ tkm and 284.67 g CO2-eq./tkm for road and rail mode, respectively. This number reveals that road mode is 2.1 times larger than rail mode. The results also indicate that the main contribution of CO2 emission from road mode is in the operation stage, which accounts for 70%
