Question

which fuel is the government insisting on to be used in vehicles? will it be helpful in reducing air pollutions?If yes, how?

Answer 1

govt. is insisting us to use CNG in vehicles...
it does not cause any pollution as it does not emit any harmful emissions..

Answer 2

The government is insisting to use CNG in vehicles as it doesn't cause air pollution. Other fuels used in vehicles combust partially and cause air pollution by giving out smoke containing carbon particles. CNG is a gas that combusts fully and does not give out smoke that contains carbon particles which will lead to reduction of pollution in the air.
