Impact of Compressed Natural Gas in Changing the Air Quality of Agartala City with reference to CO2 Emissions

Transport sector is one of the very significant sources of air pollution. The environmental effects of transport are huge because transport sectors are the major users of energy, and it burns most of the world's petroleum. Within the transport sector, road transport is the largest contributor to air pollution. Carbon emissions from conventional fuels such as petrol and diesel contribute significantly to this pollution. Sustainable approach to urban transport addresses the environmental concerns with the need to provide affordable mobility choices to the rapidly growing population of urban areas. The aim is to validate Compressed Natural Gas (CNG) as a safe alternative vehicular fuel to reduce CO2 emission in Agartala city. For that reason, an attempt to conversion of vehicles running on harmful conventional fuels into CNG fuel in the Agartala Municipal Corporation (AMC) area under three intervention scenarios has been undertaken and analyzed. The result reveals a huge change in environmental status, which makes it appropriate to conclude that the use of CNG as a vehicular fuel is the best sustainable approach in urban surface transport to significantly reduce CO2 emission.
