Answer 2

Many command and control instruments, such as banning old commercial vehicles and banning leaded petrol have been implemented to curb Delhi's air pollution. This paper is an attempt to investigate whether these efforts have led to a commensurate fall in air pollution in Delhi. Our analysis shows that it has not resulted in concomitant improvement in ambient air quality. One of the reasons is reliance on new vehicles, with little emphasis on in-service vehicles. The containment of vehicular pollution requires an integrated approach, with combined use of transport policies and air pollution control instruments.
