Explain how the use of CNG in automobiles has reduced pollution in cities?

The burning of carbon fuels produces unburnt carbon particles, particulate pollutants, smoke, oxides of sulphur and nitrogen, carbon dioxide etc into the environment which pollutes our cities. Use of CNG in our automobiles has rapidly decreased the level of pollution as CNG being a cleaner fuel produces the harmful products in very small amounts and hence, protects our environment.
