Carbon Emissions Assessment of Urban Transport - A New Approach for 10 Major Vietnamese cities

Abstract

With rapid economic development, Vietnam is experiencing substantial growth in vehicle numbers and motorized mobility. This is causing rapid increase in greenhouse gas (GHG) emissions and air pollution. There is a need to better understand the effectiveness of transport measures so as devise policy measures to reduce GHG emissions. Quantifying the emissions is vital for this. However, the databases and modelling tools for the quantification of traffic-related GHG emissions are not available in Vietnam. This study offers a practical approach to quantify road transport sector energy consumption and GHG for 10 (5 major, 5 secondary) cities located in Southern Vietnam from 2014 to 2016 based road network traffic, estimated fuel consumption and emissions factors.
