As the air quality in Delhi continues to worsen, the Graded Response Action Plan (GRAP) Stage-IV restrictions were implemented from November 18 to combat the pollution crisis. The Commission for Air Quality Management (CAQM) activated this plan to reduce harmful pollution levels in Delhi-NCR. Key measures include banning non-essential trucks from entering Delhi, except for those carrying essential goods or providing important services. In addition, the Delhi government has suspended in-person classes for all students, except for those in classes 10 and 12, to protect their health. The Stage-IV action plan also includes other steps like increasing the use of air purifiers and limiting outdoor activities. The CAQM is closely monitoring air quality levels and will continue to review the situation, taking further action if necessary to improve conditions.
