In this study the exhaust emissions emitted by the Diesel buses of Bangalore Municipal Transport Corporation have been calculated and suggested that the emission levels can be reduced drastically by the use of an alternative clean fuel CNG. The pollution loads have been calculated and compared by considering usage of the Compressed Natural Gas (CNG) in place of conventional diesel buses.

To carry out this study, the Bangalore Municipal Transport Corporation was considered and collected the required information such as the total number of buses, daily kilometres operated by the BMTC buses. Total diesel consumption every day was also collected. The BMTC buses use the diesel fuel and are responsible for largest amount of lead emissions and various other pollutants. These emissions are destroying the conducive Climatical conditions of the Bangalore city. The pollution loads have been calculated on the basis of information collected from the Central Pollution Control Board (CPCB), Environment Protection Agency and previous studies carried out in this regard by various important agencies. The use of CNG shows tremendous reduction in various pollutants in gm/km. By the use of CNG we can find 84% reduction in CO, 58% reduction in NOx and 97% reduction in PM. We can conclude that in Bangalore city (India) we can reduce CO to 9401.67 tons/year, NOx to 56797.44 tons/year and PM to 1729.917 tons/year.
