Question

Why was CNG introduced as a fuel for automobiles in a city like Delhi? Has it made any difference?

Answer 1

CNG was introduced in Delhi to reduce air pollution caused by vehicle exhaust. It burns more cleanly than petrol and diesel, releasing fewer harmful gases and soot particles. Its use has helped reduce vehicular pollution and improve air quality. However, it has not removed the problem completely, because the number of vehicles and other sources of pollution have continued to increase.
