Will the market-based approach to controlling air pollution prove more effective than enforcement methods used by pollution control boards? After failing to check air pollution through the usual enforcement methods, the Union Ministry of Environment and Forests (MoEF) has introduced a market-based mechanism to reduce air pollution. It is called the Emissions Trading Scheme (ETS). The ministry has initiated a pilot ETS in industrial areas of three states—Gujarat, Maharashtra and Tamil Nadu—with the aim of improving overall ambient air quality.

The present study deals with the effect of urbanization and automobile emission on ambient air quality of Bhubaneswar city, Odisha. This paper examines the significant difference in seasonal variations of air pollutant concentrations in the city.
