The number of cars, motorcycles and scooters coming to Panaji which has many government offices and other private offices has increased considerably and thus the emission of greenhouse gases like carbon dioxide, carbon monoxide, sulphur dioxide, nitrogen dioxides as well as particulate matter PM2.5 and PM10 has increased to a great extent. In light of this it would be suggested that ambient air quality index of the capital city which is a smart city may be monitored by installing gauges in such a way that permissible limits are displayed in green and then in that order the impermissible limits be displayed in yellow, orange and red especially at the KTC bus stand, 18th June road and Dayanand Bandodkar road which are the main thoroughfares in the city. Additionally, even the temperature and the humidity could also be incorporated in these gauges as it has been noticed that emissions seem to be now in the impermissible limits. Even the traffic department could temporarily divert traffic in that area which has exceeded the permissible limits so that the pollution levels are brought under control.
