Vehicular emission is one of the identified sources of dust. The study has been coordinated by the Central Pollution Control Board.

Based on the study conducted, the approximate contribution of transport sector to dust in residential areas varies between 9.8 to 48.3 percent in the cities. Re-suspension of road dust due to movement of vehicles is also a prominent source and accounts for 6.3 to 57.4 percent. As an outcome of the study, the Government has undertaken the task to set up Working Groups in respective thematic Ministries to deal with the sectoral recommendations of the study.
