Production of 2-wheelers and 3-wheelers vehicle has been expanding rapidly over the past several years, especially in the urbanized areas of Asia. These vehicles emit substantial quantities of pollutants such as hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NO) and particulate matter (PM). These pollutants have significant adverse health effects and deteriorate environmental quality. Presented in this paper are results of experimental study carried out to investigate the 2-wheeler emissions (CO, CO, NO, and HC) by onboard measurement method at cold start conditions, in a sub-urban area- Roorkee. Total number of hundred 2-wheelers vehicles randomly selected relatively between the 1990-2010 model years at various places. According to survey, average mileage of vehicle at the instrumentation time is 45,968 km with a maximum of 158995 km and minimum of 10,389 km. Due to the very large emissions on CO2 compare to other gases, COemissions are projected from 2000-01 to 2030-31. In projection two scenarios were discussed here first is business as usual scenario in which 2010-11, 2020-21 and 2030-31, CO intensities of all 2-wheelers modes were assumed to remain at 2000-01 levels. Second scenario was efficiency gain, where CO intensities of modal were assumed to decreases at the rate of 1% and 3% per year up to the year 2030-31.
