This study reviews and compares five databases (three global and two regional) that provide emission estimates for air pollutants in India. These databases include EDGARv5, ECLIPSEv6b, REASv3.2, SMoGv1 and TERI (2016).

The study intends to support the Delhi government, the Central Pollution Control Board (CPCB), and the Delhi Pollution Control Committee (DPCC) in identifying priority areas of interventions needed in controlling air pollution in Delhi during the winter season of 2021.
