The CAQM said all actions under Stage-I of the existing GRAP framework will be implemented with immediate effect and monitored closely by agencies concerned to prevent any further deterioration in air quality levels.

Authorities have also been directed to intensify anti-pollution measures and maintain strict vigilance, while citizens have been urged to follow the GRAP Stage-I citizen charter.
