Of them, ambient air pollution — caused by industries, cars and trucks, among others – killed 4.2 million people. While indoor pollution caused 3.8 million deaths, in 2016. In India, mitigation measures have tended to focus on Delhi although other, smaller cities too confront toxic levels of pollution. The government and judiciary have proactively led the battle against pollution. India is to switch to Bharat Stage VI vehicle emission norms in April 2020, skipping an intermediate stage.
