GRAP III Restrictions Reimposed in Delhi as Air Quality Slips Near Severe

Thick layers of smog once again cover Delhi, with many parts of the city reporting poor visibility and breathing discomfort. Residents stepped out to a strong smell of smoke and dust, while doctors warned that children, senior citizens and people with asthma or other lung issues face higher health risks.

Pollution levels rose fast over a short period, pushing Delhi’s overall Air Quality Index close to 400 by the afternoon of 13 December 2025. This level sits just below the 'severe’ band, prompting officials to move from basic restrictions to tougher steps aimed at slowing further pollution build-up.

Delhi air pollution and Stage III GRAP curbs explained

The Commission for Air Quality Management ordered immediate enforcement of Stage III of the Graded Response Action Plan across Delhi and the wider National Capital Region. Officials said this decision followed continuous tracking of pollution data and weather patterns, which showed sustained worsening and little scope for natural dispersion of pollutants.

Delhi air pollution, Stage III GRAP rules and winter pattern

Stage III GRAP brings in stricter emergency curbs meant for high-pollution days. These measures are designed to prevent air quality from sliding fully into the 'severe’ category. Authorities plan to keep close watch on coming days and may add extra controls if readings remain stuck at critical levels.

The latest restrictions highlight how Delhi’s winter air pollution remains a major public health and governance issue. Each year, cold temperatures, calm winds and local emission sources combine to trap pollutants near the surface. Policymakers now face renewed pressure to find longer-term fixes beyond seasonal emergency actions.
