The regulation for CO₂ emissions from vehicles have become much more stringent in recent years. These more stringent regulations request vehicle manufacturers to develop the alternative fuels for reducing exhaust emissions. The exhaust emission has many sources in vehicle. In this paper. it is discussed that the correlation of CO₂ emission and fuel economy in the LPG and retrofit LPG vehicles using FTP 75 and NEDC(ECE15+EUDC) mode. In order to investigate the affects of CO₂ emission to the fuel economy using existing formula that is carbon balance method, eliminate the emission terms of less contribute relatively to the fuel economy. Computational results are similar more than 99% comparison of the carbon balance method And CO₂ emission of LPG vehicles were low level relatively gasoline and diesel about 7~10%.
