India’s effort to control air pollution is centred around two major plans—National Clean Air Plan (NCAP) and the Graded Response Action Plan (GRAP). NCAP focuses on the country as a whole while GRAP focuses on the National Capital Region of Delhi (NCR). GRAP was initiated in response to the seasonal increase in the level of air pollution in the NCR. The fundamental basis of GRAP is that strict and urgent measures for varied sources of pollution are key to bringing down air pollution. GRAP assumes that if a set of measures are taken, the level of pollution with respect to particulate matter will reduce and be within the acceptable standards.
