Compressed Natural Gas (CNG) fuel has long been used in the Malaysia transport industry due to its numerous advantagous properties. CNG fuel engine considered a low carbon dioxide(CO2)emission producer presents itself a viable alternative to gasoline/ diesel fuel engines. Previous studies show that the transport industry contributes a huge percentage of CO2 emission to the environment.Therefore, this study investigates the amount of CO2 emission that can be reduced when using CNG as an alternative fuel.Performance tests were conducted on a carburetor and injector car engine using both gasoline (petrol) and CNG fuel separately. These tests were done at a variable engine speed ranging from 1000 to 3000 rpm while the exhaust gas emissions were analyzed. Although the general exhaust gas emissions were measured, the focus was on CO2 emission and the results showed that using CNG as an alternative to petrol reduces about 0.9kg/L of CO2 exhaust gas emission.Formulas collected from previous researches,were used in analyzing the possible amount collected from previous researches, were used in analyzing the possible amount of CO2 emission that can be reduced by the year 2020 in the Malaysia transport industry. This analysis was a necessary to encourage the total acceptability of CNG fuel usage in the transport industry. However, from this study, it was found that the possible amount of CO2 emission that can be reduced with the use of CNG vehicle by the year 2020 would be about 4,018,546-tons CO2 emissions as against an estimated 3,058,254 CNG vehicles. vehicles. Therefore, with this level of increase Malaysia could meet up with other higher this level of increase Malaysia could meet up with other higher this level of increase Malaysia could meet up with other higher CNG users around the world like Iran and Pakistan.
