Transport sector is the largest energy consuming sector in India. Further road transport is the most predominant sector with reference to emissions of carbon dioxide and other pollutants. It is well known that global air pollution is related to local air quality. Present paper deals with baseline inventory of greenhouse gas emissions and other criteria pollutants. Quantification of greenhouse gases (GHG) and criteria pollutant emissions has been done adopting top down and bottom up approach as recommended in Intergovernmental Panel on Climate Change (IPCC)2006 guidelines. Default emission factors are used in the inventory. The estimated direct greenhouse gases Carbon Dioxide (CO2),Methane (CH4) and Nitrous oxide (N20) are in the range of 2.19-2.24 Million tonnes, 325-350 tonnes and 19 tonnes respectively. In addition estimation of criteria pollutants have shown that 51221 tonnes of Carbon monoxide (CO), 17931 tonnes of Hydrocarbons (HC), 26300 tonnes of Oxides of Nitrogen (NOx) and 2467 tonnes of Particulate (PM) are released in the year 2005-06. Also, BAU scenario has been considered to the year 2020 where in emissions has found to nearly double the baseline inventory. The other alternative scenario to meet growing need for public transportation such as metro rail transit system has also been considered. The alternative scenario considered has shown 30% reduction in GHG emissions when compared with baseline scenario.
