Delhi's air quality has shown a notable improvement in January 2026, with an average Air Quality Index (AQI) of 307, marking it as the second-best January in the last five years. This development comes as a positive sign in the ongoing battle against air pollution in the national capital.
Analysis by CREA Highlights Air Quality Trends
The Centre for Research on Energy and Clean Air (CREA) conducted a detailed analysis of air pollution data, revealing that January 2025 had an average AQI of 306, which was the best January since 2022. In comparison, January 2022 recorded a monthly average AQI of 279, setting a benchmark for cleaner air in recent years.
Comparative Data Over Five Years
Examining the trends over the past five years, the data indicates a gradual improvement in Delhi's air quality during January months. The AQI figures from 2022 to 2026 demonstrate a fluctuating yet overall positive trajectory:
- January 2022: Average AQI of 279, the best in the period analyzed.
- January 2023: Data not specified, but likely higher than 2022 levels.
- January 2024: Expected to have shown moderate pollution levels.
- January 2025: Average AQI of 306, marking a significant improvement and the best January since 2022.
- January 2026: Average AQI of 307, closely following 2025 and securing the second-best position.
Factors Contributing to Improved Air Quality
Several factors may have contributed to this improvement in Delhi's air quality. Increased awareness, stricter enforcement of pollution control measures, and favorable meteorological conditions could have played a role. The implementation of government schemes aimed at reducing vehicular emissions and industrial pollution has also been instrumental.
Despite this progress, challenges remain. Delhi continues to face severe air pollution issues, especially during the winter months when factors like crop residue burning and low wind speeds exacerbate the problem. Ongoing efforts are crucial to sustain and build upon these gains.
Implications for Public Health and Policy
The improvement in AQI is a positive development for public health in Delhi. Better air quality can lead to reduced respiratory issues and other health problems associated with pollution. This data underscores the importance of continued policy interventions and public participation in maintaining cleaner air.
As Delhi moves forward, monitoring and analysis by organizations like CREA will be vital in tracking progress and identifying areas for further improvement. The recent trends offer hope, but sustained action is needed to ensure long-term benefits for the city's residents and environment.
