Delhi's air quality during the winter season has shown significant fluctuations, with recent improvements noted. As of December 16, 2024, Delhi has experienced the highest number of 'good' and 'moderate' air quality days since 2018. This improvement is a notable shift from the severe pollution levels observed earlier in the season.
Preview
In November 2024, Delhi recorded its highest-ever Air Quality Index (AQI) level, reaching an unprecedented 795 on November 18. This extreme pollution level was attributed to various factors, including stubble burning in neighboring states, temperature inversions, and increased vehicular emissions during the Diwali festival. The severe pollution led to widespread health issues, with hospitals reporting a surge in patients suffering from respiratory problems.However, recent data indicates a positive trend. On December 14, 2024, the AQI in Delhi was recorded at 193, categorized as 'moderate'. This improvement is part of a broader trend where the city has seen more days with 'good' to 'moderate' air quality compared to previous years. The Graded Response Action Plan (GRAP) has been revised to include stricter measures to combat pollution, such as banning certain vehicles and implementing hybrid learning for schools during severe pollution days.Overall, while Delhi's air quality remains a significant concern, especially during the winter months, recent efforts and improved conditions suggest a potential for better air quality management in the future.
