National Clean Air Programme (NCAP), was launched by the Ministry of Environment, Forest and Climate Change (MoEFCC) in 2019, with the target to reduce particulate matter concentration level by 20-30% in several non-attainment cities in India. These non-attainment cities do not meet the National Ambient Air Quality Standards (NAAQS). Bengaluru has been identified as one of the non-attainment cities of India under NCAP. Considering this, the Government of Karnataka has been trying to generate scientific evidence on the causes of air pollution and to identify sectoral control measures to improve the quality of air in the city. As part of its efforts to generate scientific evidence on air pollution, the Department of Forest, Ecology and Environment (DoFEE) along with the Karnataka State Pollution Control Board (KSPCB) invited the Center for Study of Science, Technology, and Policy (CSTEP) in 2018 to conduct an emission inventory (EI) study for Bengaluru.
