This paper examines that transportation generates maximum pollution in Howrah district mainly in urban area. Development & urbanization has led this city population increased very rapidly in the recent past. Howrah has a well connectivity of multimode road network which is very benefiting the population but use of conventional fossil fuel slowly ruining the Biodiversity and National Wealth like Water. Vehicular emissions from transport sector are main sources of chemical hazard, which releases toxic gases to the atmosphere, like NOx, SO2 & CO, mixes with air & condense with water, evaporates to form cloud and then reaches the ground in the form of acid rain, which contaminates the fresh water sources & damages the water bodies/resources at large. This can be reduced by using of bio fuel in mixture 10% with the petroleum products.
