With 2.51 million deaths in 2015, India has been ranked No. 1 in pollution-related deaths, according to a report by The Lancet Commission on pollution and health. China recorded the second highest number of such deaths (1.8 million). India accounted for about 28 percent of an estimated nine million pollution linked deaths worldwide in 2015.
The Lancet Commission on pollution and health is a two-year project in which more than 40 international health and environmental authors led by environmental scientist Philip Landrigan were involved.
