Study the current status of emissions from motorbikes in Hanoi and propose control solutions

Abstract

The study randomly measured the emissions of 5,240 motorbikes that have been in use from 1966 until now. The results indicate that motorbikes begin to show a trend of exceeding allowable emission limits (TCVN 6438:2018) after 7 years of use, with motorbikes older than 12 years exceeding standards by up to 51% based on at least one parameter, either CO or volatile organic compounds (VOCs)...
