Air pollution, especially particulate matter, is a serious challenge in India, and transportation is a significant factor in the nation’s air-quality problems. Premature deaths from diseases directly related to air pollution in India total 1.1 million a year. The country’s vehicle fleet is expanding rapidly with sales reaching 21 million in 2016, and the number of vehicles on the road is expected to double to 200 million by 2030. In 2016, India adopted Euro 6/VI-equivalent standards to go into effect in 2020. The ICCT’s India staff works with policymakers to further mitigate vehicular air pollution.
