Environmental Effects:
Due to the more natural form of CNG, it is preferred by many environment conscious consumers over gasoline in running vehicles. CNG reduces emissions of harmful gases like carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxide by huge percentages.
Moreover, burning of CNG expels lower amounts of carcinogenic particles into the air. Burning gasoline on the other hand produces large amounts of CO and CO2 which leads to the greenhouse effect, commonly known as global warming.
