Solution

Automobile emissions are a major cause of air pollution in metro cities. Their added increase in number has worsened the situation.
Ways to control this include:-
  • Use of unleaded petrol and low-sulfur or sulfur-free
  • Use of catalytic converters to reduce the emission of poisonous gases
  • Application of stringent pollution-level norms for vehicles such as Bharat Stage III and Bharat Stage IV that specify mass emission standards for the vehicles.
