The analysis clearly indicates that even the most stringent emission control measures, if restricted to the Ha Noi area, will not be sufficient to effectively approach Vietnam’s national ambient air quality standards.

In 1998 Beijing began an intensified air pollution control program, and over the last 20 years the city has implemented a series of measures including energy infrastructure optimization, coal-fired pollution control, and vehicle emission controls. These efforts successfully reduced air pollution.

India’s national capital region (NCR) emerged as the most polluted region in the world in 2018, according to this new report. Gurugram is the worst affected followed by Ghaziabad, Faridabad and Noida are amongst the top six most worst-affected cities.

Some 385,000 people worldwide died prematurely in 2015 from air pollution caused by vehicle exhaust emissions finds this study published by International Council on Clean Transportation (ICCT) which singled out diesel engines as the main culprit. China, the EU, the United States, and India accounted for 70% of global transportation-attributable PM2.5 and ozone deaths but just under half of the global population.
