The emission of the greenhouse gases is one of the disadvantages of standard gasoline and other types of fossil fuels. These gases affect our climate and acts as a major source of air pollution. The continued use of fossil fuels for powering of internal combustion engine is being debated. The compressed natural gas proves to be effective and clean alternative to gasoline. This fuel is created by compression of traditional natural gas and its storage in the canisters. It can be used in many ways including the clean fuel for internal combustion engine operating in numerous motor cars. It is also becoming famous in Europe and South America due to continuing rise in gasoline prices.

South America has the largest market share of global Natural Gas Vehicle with 48% of the total NGV. The CNG cars have proven to be major alternative to gasoline-driven models. It is done by retrofitting gasoline models with the CNG Kit needed for operating the vehicle on CNG rather than gasoline. The usage of CNG is practised a lot in Brazil and Argentina that run approx 3 million of the world’s fleet out of 7 million NGVs. In fact, most of the taxi cabs in these two countries are CNG based and takes the benefit of government initiative for making the conversion to CNG cheaper and easier. As South America has the largest reserve of natural gas, most of the countries are increasingly using the CNG.

There has been continuous rise in CNG in the developed countries of the world.  One of the major factors that attract the persons to use CNG is that it is cheaper alternative and those who run it would pay up to 60% less as compared to gasoline. It is environmentally friendly gas that is answer to our needs of clean fuel in today world that is threatened by the global warming.
