Delhi has been engulfed in hazardous levels of air pollution, with the AQI consistently breaching the "severe plus" category. Authorities have activated Stage 4 of the Graded Response Action Plan (GRAP), which includes bans on diesel vehicles, suspension of construction activities, and shifts to remote work and online education. The measures aim to curb emissions from vehicles and industries while tackling the immediate health risks posed by PM2.5 and PM10 pollutants. Residents are advised to minimize outdoor activities and adopt cleaner energy solutions to combat the crisis.
