Ahmedabad Air Quality Index
Ahmedabad, Gujarat's commercial capital, faces serious air quality challenges driven by one of India's densest industrial zone clusters. The Vatva-Naroda-Odhav GIDC belt of 4,200+ industrial units combined with extreme summer heat and winter inversions makes Ahmedabad one of India's most consistently polluted cities.

Frequently Asked Questions
What is Ahmedabad's AQI in 2024?
Ahmedabad's annual average AQI in 2024 is approximately 113 (Unhealthy for Sensitive Groups). The city sits in a semi-arid zone where dry conditions, industrial emissions, and summer heat combine to create persistent air quality problems. December–January (AQI 145–155) and November (148) are the worst months.
How does Ahmedabad's textile industry affect air quality?
Ahmedabad and the surrounding GIDC (Gujarat Industrial Development Corporation) zones — particularly Vatva, Naroda, Odhav — host thousands of textile dyeing, printing, and chemical units. These emit PM2.5, volatile organic compounds (VOCs), and in some cases SO2. Vatva GIDC alone covers 4,200+ industrial units making it one of Asia's most polluted industrial estates by facility count.
Why is Ahmedabad's summer air worse despite heat?
Extreme heat in Ahmedabad (temperatures regularly reaching 44–47°C in May) accelerates photochemical reactions that form ground-level ozone from vehicle NOx. Hot, dry air also desiccates soil, lifting fine dust aerosols. The semi-arid landscape provides abundant dust sources when wind speeds increase. Paradoxically, hot summer air that should cause convective mixing sometimes creates local circulation patterns that trap pollution.
Which areas of Ahmedabad have worst air quality?
Vatva GIDC, Naroda GIDC, Odhav, and Kathwada industrial areas consistently register the highest pollution readings. Eastern Ahmedabad (Ghodasar, Vastral) near industrial estates is significantly worse than western areas (Satellite, Bodakdev, Vastrapur). South Ahmedabad near Narol and Isanpur also shows elevated industrial PM. Gandhinagar, the state capital 25km north, benefits from a planned urban layout and has markedly better air.
Does Navratri/Diwali significantly affect Ahmedabad's air?
Yes — Navratri generates noise pollution primarily, but Diwali firecrackers in Ahmedabad create acute PM2.5 spikes of 200–400+ μg/m³ over 2–3 days, compounded by cold November air that prevents vertical mixing. The city has attempted cracker bans but enforcement is limited. Diwali 2023 saw Ahmedabad AQI exceed 300 (Hazardous) for nearly 18 hours.
