Sun Jan 18 12:40:00 UTC 2026: ### Delhi Chokes: GRAP-4 Implemented as Air Quality Plummets

The Story:
Delhi and its surrounding areas are once again grappling with severely degraded air quality. The Air Quality Management Commission (CAQM) has implemented Grade-4 of the Graded Response Action Plan (GRAP) in response to the deteriorating conditions. On Saturday evening, the capital’s Air Quality Index (AQI) reached 428, a level considered hazardous to health, prompting authorities to take stringent measures.

The implementation of GRAP-4 brings a complete ban on all construction and demolition activities in Delhi, as dust from these sources significantly contributes to pollution. Furthermore, the entry of trucks into the capital has been prohibited, with limited exceptions for essential services vehicles. To protect children, all schools in Delhi have been instructed to conduct classes in hybrid mode, offering both online and offline options to minimize exposure to the toxic air.
