Greenhouse Gas Emission from Freight Transport-Accounting for the Rice Supply Chain in Vietnam

Abstract

The freight transport related greenhouse gas emission has been increasing quickly in Vietnam. Vietnamese government is aiming for CO2 reduction, which focuses on accurate definition of the contribution of different industry sectors to greenhouse gas emission. The objective of this paper is a summary of studies on transport emission factors in Vietnam and other countries in the world. As a consequence, the conclusion on emission factors currently used in Vietnam is generated. The study takes the rice industry in Vietnam as an example sector for the detailed examination of total emission. The preliminary results show that nearly 100 tons of CO2 were emitted from freight movement in the rice industry in 2011, approximately 0.8% of total CO2 emission borne by freight transport sector of Vietnam. Besides, modal shift from the road to inland waterway transport in the rice supply chain can bring benefits for not only the rice industry but also environmental protection.
