Calculation of Fuel Baseline and CO₂ Emission for Heavy Duty Vehicles in Viet Nam

Abstract

Nowadays, the demand for transporting passengers and goods is increasing so the number of trucks and passenger vehicles in Vietnam as well as other countries in the world is continuously increasing to meet such demand. The increase in the number of trucks and passenger vehicles has caused consequences related to environmental pollution, particularly (PM) and CO₂ emissions. GFEI’s partners agreed with the objective of reducing 35% (referred to as the “35/35 program”) of heavy-duty vehicles (HDV) average fuel consumption across the world by 2035. The basis of such reduction is presented by the International Council on Clean Transportation (ICCT) based on a report published in 2016 which assessed the potential for improving fuel savings of HDVs in major markets. The reduction of HDV fuel consumption by 35% in the period of 2015–2035 can be considered as an ambitious target but it is achievable. The paper presents the results of the analysis of the current state of new HDV in Vietnam based on the Global Fuel Economy Initiative (GFEI) Index for the period 2010–2019. Results show that if cutting down fuel is currently maintained, by 2035, the CO₂ emissions level of heavy-duty trucks and passenger vehicles will be reduced about 32% compared to that of 2015. The calculation results of GFEI and CO₂ emissions can be used as a reference for the development of emission index for motorized vehicles and scientific basis for manufactures, assemblers and regulators to reduce fuel consumption and CO₂ emissions.
