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

Delhi's average AQI clocked 59 today. The earlier recorded best AQI of Delhi during current year was 64 on 9th July.

An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

"The city government is close to delivering on its promise of planting two crore saplings in the national capital in five years," he said.

Improving Delhi's air quality has been most difficult task: CM Kejriwal

A day after the Environment Ministry said Delhi registered the highest number of 'good to moderate' air quality days this year since 2016, barring 2020, Chief Minister Arvind Kejriwal Saturday said improving air quality in the city has been the most difficult task. Delhi also experienced the least number of days with 'poor to severe' air quality in the first half-year period (January to June) in 2023, compared to the corresponding period since 2016, except for COVID-19 affected 2020. "This was perhaps the most difficult task -- improving air quality. But a series of steps taken by Delhiites helped us achieve this seemingly impossible task. Still a long way to go. But Delhi people have always done what others thought impossible," Kejriwal said in a tweet. The average AQI (air quality index) for Delhi during this period also remained in 'moderate' category -- below 200. Delhi reported its lowest average AQI during 2023 (JanuaryJune) compared to the corresponding period for the seven .

Canadian wildfires causing unhealthy air quality again in parts of US

Officials to use anti-smog guns amid spike in AQI: Environment Minister

Owing to the deteriorating air quality in the national capital, Delhi Environment Minister Gopal Rai Thursday directed officials to run anti-smog guns throughout the day and sprinkle water at construction and demolition (C&D) sites. The recent bump in the air quality index (AQI) of the national capital was due to strong dust-laden westerly winds from the Thar desert and Pakistan, Rai said at a review meeting with officials of his department and the Delhi Pollution Control Committee (DPCC) at the Delhi Secretariat. "The Kejriwal government has always taken tough steps to curb increasing pollution in Delhi," an official statement quoted Rai as saying. The minister added, "On May 16 and 17, a significant portion of Delhi and NCR was engulfed by dust, causing reduced visibility." The contribution of dust pollution to PM10 levels rose from 11 per cent during May 1-15 to 65.77 per cent from May 16-17, Rai added. On Tuesday, the DPCC data showed PM10 levels soaring to 3,826 micrograms ..
