Synopsis
Key Takeaways
- Global air quality rankings are unofficial.

- Farm fire incidents have significantly decreased in Punjab and Haryana.
New Delhi, Dec 11 (NationPress) The rankings of global air quality referenced by multiple organizations lack verification from any official body, as stated by the government in Parliament on Thursday.
In a formal response within the Rajya Sabha, Minister of State for Environment Kirti Vardhan Singh mentioned that the often-quoted international rankings, including IQAir World Air Quality Report, WHO Global Air Quality Database, Environmental Performance Index (EPI), and Global Burden of Disease (GBD), are not overseen by any recognized authority.
These rankings are intended solely as advisory guidelines, not mandatory benchmarks.
Singh elaborated, "The World Health Organisation's air quality recommendations are merely suggestions aimed at aiding nations in achieving satisfactory air quality. Each country formulates its own air quality regulations based on factors such as geographical conditions, environmental variables, socio-economic status, and national specifics."
The Environment Ministry further noted that it established the National Ambient Air Quality Standards (NAAQS) for twelve pollutants in 2009 to safeguard public health and the environment, specifically tailored to India's unique conditions.
While the World Health Organisation revised its air quality recommendations in 2021 (24-hour PM2.5 threshold: 15 micrograms per cubic meter; annual: 5 micrograms per cubic meter), India continues to adhere to its 2009 standards (24-hour PM2.5: 60 micrograms per cubic meter; annual: 40 micrograms per cubic meter), which the government asserts are suitable for national circumstances.
In a related update, Environment Minister Bhupender Yadav emphasized the notable enhancement in Delhi's air quality in recent years due to targeted policy measures.
He reported an increase in the number of days categorized as "Good to Moderate" (AQI ≤ 200) in Delhi, rising from 110 in 2016 to 200 in 2025 (to date).
Yadav added that the average AQI (January-November) improved from 213 in 2018 to 187 in 2025, with no recorded days of "Severe Plus" (AQI > 450) in the capital during 2025.
Notably, incidents of farm fires in Punjab and Haryana decreased by approximately 90% during the 2025 paddy harvesting season compared to 2022.
