Delhi-NCR recorded an average Air Quality Index (AQI) of 167 from January 1 to September 30 this year, the second-best for the corresponding period in six years, the Centre's Commission for Air Quality Management (CAQM) said on Saturday. Better air quality during this period was recorded only during the pandemic-affected 2020, it said in a statement. In 2022, 2021, 2019 and 2018, the average AQI during this period ranged from 180 to 193. Delhi experienced its only "good" air quality day of the year, with an AQI of 45, on September 10, the final day of the G20 Summit. Despite less rainfall in September 2023 (82.7 mm) compared to September 2022 (165 mm), the average AQI for the month this year (108) remained on par with last year (104). Between January and September this year, Delhi saw 193 days with "good" to "moderate" air quality (average AQI less than 200), surpassing the previous five years (excluding 2020), during which the number of such days ranged from 146 to 174.

Centre's action plan to curb air pollution in Delhi comes into force Sunday

The Graded Response Action Plan -- a set of anti-air pollution measures followed in the Delhi-NCR region in the winter season -- will come into force on Sunday. The Commission for Air Quality Management, an autonomous body tasked with improving air quality in Delhi and the adjoining areas, had made crucial changes to the Graded Response Action Plan (GRAP) last year and again in July this year. The new changes include strict restrictions on the plying of overage vehicles and a complete ban on the use of coal and firewood in eateries, restaurants and hotels when the air quality index (AQI) breaches the 200 mark. BS III petrol and BS IV diesel four-wheelers will be immediately banned in Delhi and Gurugram, Faridabad, Ghaziabad and Gautam Buddh Nagar if the Air Quality Index (AQI) crosses the 400 mark. The Commission for Air Quality Management (CAQM), a statutory body formed under an Act in 2021, had amended the GRAP in July last year to ensure proactive implementation of anti-air ...

Intense, frequent heatwaves measurably worsening air quality: WMO

Increasingly intense and frequent heatwaves, compounded by wildfires and desert dust, is measurably worsening air quality, according to a new report by the World Meteorological Organization (WMO). Putting heatwaves in the spotlight, the report showed that heatwaves in the US and Europe, triggering wildfires and accompanied by desert dust intrusions, respectively, both led to dangerous air quality in 2022, affecting human health and environment. It is not just high temperatures which are a hazard, but the impacts of resulting pollution, often overlooked, are just as pernicious, the 2023 WMO Air Quality and Climate Bulletin, the third in an annual series, said. Air quality and climate are interconnected because the chemical agents affecting both are linked. This is because the substances contributing to climate change and degrading air quality are often emitted by the same sources. For example, fossil fuel combustion emitting carbon dioxide (CO2) and nitrogen oxide (NO) can lead to t
