Indore (Madhya Pradesh): The city has recorded lower air pollution levels in the financial year 2024-2025, with a significant reduction in fine particulate matter (PM2.5 and PM10), black carbon and dust as compared to the previous financial year (2023-2024).

In this period, the city’s Air Quality Index (AQI) has seen an average decrease of 27.56%, reflecting the success of stringent pollution control measures and enhanced monitoring. Pollution Control Board scientist Sanjay Jain said that the authorities had set up air quality monitoring stations at key locations, including Chhoti Gwaltoli, Residency Area and Vijay Nagar Scheme-78.

Additionally, 19 air pollution sensors have been installed at major junctions such as Satya Sai Square, Vijay Nagar Square and Palasia Square, providing real-time data. Under the ‘Non-Attainment City’ programme, new stations are planned at Mhow Naka, Regional Park, Fine Arts College and Vijay Nagar to further strengthen air quality surveillance. The decline in pollution levels is credited to several strategic measures.

Mechanised road sweeping and stringent regulations on construction activities have significantly reduced dust levels. Industries have adopted pollution control devices like bag filters and brick kilns have been relocated outside the city limits to curb black carbon emissions.

Additionally, eateries have switched over to cleaner fuels such as piped natural gas (PNG), reducing overall emissions. In cases of rising Air Quality Index (AQI), authorities respond with immediate action, including intensified vehicle inspections to enforce Pollution under Control (PUC) norms, stricter industrial emission oversight and enhanced dust control measures. August saw a significant drop in pollution levels due to the sustained implementation of these measures. Indore’s proactive approach to air quality management has set a benchmark for urban pollution control in India, positively impacting environmental sustainability.  

The highest AQI recorded in the FY 2023-2024 was in November at 138, which saw a notable reduction to 90.8 in the same month in FY 2024-2025, marking a 34.20% decrease. Similarly, October had an AQI of 137 in 2023-24, which declined to 92.25 in 2024-2025, reflecting a 32.65% reduction.  

The lowest AQI was observed in August, where it dropped from 91 in FY 2023-2024 to 45.4 in FY 2024-2025, showing a 50.11% decrease—the most significant reduction recorded so far.
