Urban India, particularly metros, is a major hotspot of air pollution with a PM2.5 concentration level ranging above the permissible limits defined by the WHO for most of the year. Unsurprisingly, special efforts have been made by the Government of India in recent years to improve air quality. Since the transport sector is a major source of air pollution in urban India, the Government of India adopted BS-VI emission standards in 2016 in principle for all major on-road vehicle categories. The rollout of Euro 6 in India began with the capital city Delhi. Furthermore, India’s policymakers have been proactive in introducing clean fuel such as CNG, as well as electric vehicle and hydrogen fuel vehicles for urban transport. In this paper, analyze the interplay between the policy shifts on transport and the level of emissions for Delhi for the next 10 years.
