| Abstract | Traffic emission contributes significantly to total air pollution in Hanoi. This study conducted an emission inventory for public transport fleets (bus, taxi) and personal cars in Hanoi for the year 2010 and projected the emission to 2015 under 3 scenarios using the International Vehicle Emission (IVE) model. The effects of the technology implementation scenarios on air quality and climate were assessed. The results of this study and the results of a previous study were combined to produce the total passenger transport fleet emission in Hanoi for 14 pollutants. The inventory results for 2010 of common pollutants including CO, VOC, NOx, SOx and PM in tonnes per year for the bus fleet were respectively 35,800; 8,950; 87,800; 600 and 10,940 and for the taxi fleet were 429,200; 73,790; 17,000; 1,470 and 240 while for personal car fleet were 314,800; 55,660; 25,070; 2,660 and 360. The total emission of all passenger transport fleet (including motorcycles) were 928,930; 186,340; 138,860; 4,890 and 13,790; respectively. The taxis and personal cars were the major contributors to CO, VOC and SOx emissions while PM and NOx were mainly generated from buses and motorcycles. Climate forcing was calculated in term of CO₂ equivalent of the total emission of greenhouse gases (GHGs), O₃ precursors, BC and OC. By 2010, under scenario 1 (all vehicles should at least meet Euro II) and scenarios 2 (all vehicles should meet Euro III) plus the old vehicle scrappage would lead to considerable benefits in reduction of emission of toxic air pollutants and climate forcing agents as compared to the business as usual (BAU). Application of Euro III would get substantial benefit on air quality, i.e. a reduction by 80% of total five common pollutants (CO, VOC, NOx, PM and Benzene) as compare to BAU. Switching to Euro III (scenario 2) would bring considerable benefits of air pollution emission reduction as compared to scenario 1 but not as much gain for climate mitigation, i.e. a further reduction by only 1.5% of total CO₂ equivalent. Further study should include the emission of other types of vehicle, such as trucks and other off-road vehicles in Hanoi. The emission inventory of other non-transport sources should be prepared and used for the effective air quality management and develop necessary climate mitigation strategies. |
