Delhi Chief Minister Arvind Kejriwal had earlier announced a 15-point winter action plan to curb the pollution caused by vehicles, biomass burning, dust, etc. Now this winter action plan is being implemented on the ground one by one to reduce pollution in the national capital. 

'Red Light on, Gaadi off' campaign

Since the pollution in national capital is increasing with the each passing day, Delhi government also started the 'Red Light on, Gaadi off' campaign 

The data says that in AQI the level of Particulate matter (PM) 10 is decreasing and that of PM2.5 is increasing. This means that pollution caused by vehicles and biomass burning is increasing. For this, the 'Red Light on, Gaadi off' campaign has been started. 

Notably, Air Quality Index (AQI) is a tool for effective communication of air quality status to people in terms, which are easy to understand. It transforms complex air quality data of various pollutants into a single number (index value), nomenclature, and colour
