Coal-based power plants aggravating air pollution in Delhi-NCR: Report

Non-compliance of thermal power plants in Delhi-NCR with emission standards is contributing significantly to air pollution in the region, according to a new analysis. The study by environmental think tank Centre for Science and Environment (CSE) focuses on particulate matter, nitrogen oxide and sulphur dioxide emissions from the 11 thermal power plants (TPPs) in Delhi-NCR and is based on their environmental status reports sourced from the website of the Central Electricity Authority (CEA), a technical arm of the Union Ministry of Power, from April 2022 to August 2023. According to studies, the TPPs account for around eight percent of the PM2.5 pollution in Delhi-NCR. "Delhi-NCR cannot achieve the clean air benchmark and safeguard public health if continuous sources of pollution, such as thermal power plants, continue to emit pollutants at high levels. These plants have struggled to meet the standards, primarily due to continually shifting compliance deadlines, says Anumita ...

Delhi's air quality 'severe' again, brief relief likely next week

Air quality in Delhi turned 'severe' again on Friday with a dip in temperatures and slow wind speed at night allowing accumulation of pollutants. The city's air quality index (AQI) that stood at 401 at 8 am had worsened to 415 by 4 pm. A scientist at the India Meteorological Department (IMD) predicted a brief relief due to a likely improvement in meteorological conditions under the influence of a western disturbance expected to affect northwest India starting November 27. Delhi has been witnessing a gradual increase in AQI levels after a marginal improvement on Sunday. The 24-hour average AQI, recorded at 4 pm every day, was 390 on Thursday, 394 on Wednesday, 365 on Tuesday, 348 on Monday and 301 on Sunday. The rise in the AQI levels comes after the Centre on Saturday removed stringent curbs, including a ban on construction work related to linear projects and the entry of polluting trucks in Delhi, following a drop in pollution levels due to a favourable wind speed and ...

Strictly implement curbs on polluting vehicles, biomass burning: Gopal Rai

As air quality turned severe again in the national capital, Delhi Environment Minister Gopal Rai on Friday directed agencies and departments concerned to ensure strict implementation of curbs on polluting vehicles and check the increasing incidents of biomass burning. Recent data shows that vehicular emissions account for about 25-30 per cent of the capital's air pollution. Though stubble burning has reduced, biomass burning at different locations in Delhi-NCR is responsible for 21 per cent of Delhi air pollution, Rai told reporters here. Earlier during the day, Rai chaired a meeting with senior officials of various departments to review the air pollution situation. He said the transport department and the Delhi Traffic Police have been asked to strictly monitor the implementation of curbs on BS III petrol and BS IV diesel vehicles under stage III of the Centre's air pollution control plan called the Graded Response Action Plan. The Municipal Corporation of Delhi and the revenue ..

Buses from other states may face curbs if Grap Stage IV invoked in Delhi

The Delhi government has notified that the entry of buses, barring CNG, BSVI diesel and electric ones will be regulated in the capital, if restrictions under the final stage of the Centre's air pollution control plan are invoked. Stage IV is the final stage of the Graded Response Action Plan (GRAP). "Entry of all buses, including All India Tourist buses/ Contract Carriage buses/ State Transport Buses or holding any other kind of permit into Delhi from other states except CNG / Electric or BSVI diesel buses will be restricted as and when GRAP IV invokes. "The above mentioned restrictions shall stand automatically applicable, as and when GRAP - IV is invoked from the date of issuance of this order in Delhi Gazette, and if the GRAP IV is revoked the said restrictions stand terminated automatically, no separate order will be issued," an official gazette notification said. Last month, the Delhi government directed that all buses entering the national capital from Haryana will have to be

Stubble burning, a major cause of Delhi air pollution: Punit Renjen

Stubble burning, which is a major source of air pollution in the national capital region every winter, is a solvable problem, said Indian-American Punit Renjen, the Deputy Chair of German software firm SAP, based on the two pilot projects he has launched in Haryana and Punjab. It is very serious and there are multiple reasons for it. But stubble burning contributes about 25 per cent to 30 per cent of the air quality issues (in Delhi). There are 80,000 fire incidents in northern India, particularly in Punjab, Haryana, and Uttar Pradesh. About 13 million tonnes of stubble is burned and 19 million tonnes of carbon dioxide and other harmful gases are put into the atmosphere, Punit Renjen told PTI. The top Indian American CEO, who has made part of his mission to help fight air pollution in the national capital region, said 15 million adjusted life years is equivalent to 2 lakh people dying each year as a result of stubble burning. "There's USD 300 million of lost revenue," who is also th

Air pollution levels in Delhi down but need to remain vigilant: Gopal Rai

Environment Minister Gopal Rai on Sunday said that although the air quality in Delhi has shown improvement in the past two days, people should remain vigilant and adhere to pollution control measures. Rai also recalled that the progress made just before Diwali due to rain and favourable meteorological conditions was compromised by people bursting firecrackers. "Despite the recent improvements, it's crucial to stay cautious and follow all air pollution control measures," the minister told reporters. Delhi and its suburbs witnessed a further improvement in air quality on Sunday, attributed primarily to favourable atmospheric conditions such as wind direction and speed. At 7 am, the city's Air Quality Index (AQI) stood at 290. The 24-hour average AQI was 319 on Saturday, 405 on Friday and 419 on Thursday. 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', 401 and 450 'severe', and above 450

Delhi's air quality now in 'poor' category with 209 AQI, govt lifts curbs

On Friday, Delhi's AQI was close to falling into the "severe plus" category, following which, the government would have implemented the odd-even car rationing measure

Take all possible immediate remedial measures to improve AQI: NGT to states

The National Green Tribunal has observed that the various states where the Air Quality Index deteriorated did not fully comply with its earlier direction to take "immediate remedial action". Expressing dissatisfaction over the pollution situation in these states not showing any "significant improvement", the tribunal directed the authorities concerned to review their approach, come up with adequate measures to improve the air quality and submit a further action taken report. The tribunal had earlier issued notices to the chief secretaries of several states, including Delhi, Haryana, Punjab, Rajasthan, Madhya Pradesh, Uttar Pradesh, Maharashtra, Gujarat, Bihar and Jharkhand, after taking cognisance of the Central Pollution Control Board's online air quality bulletins. Some cities in these states showed the Air Quality Index (AQI) as 'severe', 'very poor' and 'poor', the tribunal had observed. An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200

Delhi's AQI close to 'severe plus'; odd-even rule may be imposed soon

Delhi L-G slams city, Punjab govts over air pollution; AAP hits back

Lieutenant Governor V K Saxena came down heavily on the AAP governments in Punjab and Delhi on Thursday, alleging that the former is playing "truant" on the issue of stubble burning and the latter involved in "over-hyped events" like the odd-even road-rationing scheme, while the national capital is gasping for breath due to alarming levels of air pollution. Setting the stage for a fresh confrontation between the LG's office and the Aam Aadmi Party (AAP) dispensation in Delhi, Saxena asserted that blaming others for the pollution problem will not help and the solution lies within the city itself. In a statement, the AAP said the Delhi government has taken a slew of measures over the past several years, which has led to a significant improvement in the air quality, as was appreciated in the Economic Survey 2022-23 tabled in Parliament. The party said it has taken several measures even in Punjab and if the Centre provides a subsidy, many more things can be done to curb farm fires. As t

Smog towers not practical solution to air pollution: Delhi pollution board

Two experimental smog towers in the city have not been effective in reducing air pollution and the operation of these costly giant air purifiers lacks merit, the Delhi Pollution Control Committee (DPCC) has told the National Green Tribunal (NGT). In a report submitted to the NGT last week, the pollution control body emphasised that smog towers cannot be a "practical solution" to the air pollution problem and the two such structures in Delhi should be re-purposed for the "dissemination of technical information on air pollution control as a museum". In the report, DPCC's senior scientist Nandita Moitra said the Rs 25-crore smog tower at Connaught Place, operational for two years, can only mitigate air pollution by up to 17 per cent within a 100-metre radius. Considering Delhi's vast area of 1,483 square kilometres, the pollution control body said the city would need more than 47,000 such towers, with each costing Rs 25 crore for installation and requiring Rs 15 lakh monthly for ...

Delhi pollution row: LG Saxena attacks Delhi, Punjab govts over crisis

Lt Governor V K Saxena on Thursday targeted AAP governments in Delhi and Punjab over air pollution in the city, saying Delhi can do little to stop smoke from stubble-burning from other states. He also highlighted that the problem in the national capital can be mitigated by reducing "dust that our unrepaired roads, unpaved pavements and construction sites cause" and curbing vehicular emissions. Saxena said the national capital can do little to stop crop residue smoke from other states and added "blaming others should not be alibi for gross inaction over years." Saxena also accused the Punjab government of "playing truant." "We can do little to stop crop residue smoke from other States, apart from pleading with them. Despite States, especially Punjab playing truant, we are, but petitioners for mercy. AQI yet hovers around 400, making the capital gasp," he said in a post. Delhi's air quality fluctuated between "very poor" and "severe" categories on Thursday as unfavourable meteorolog

Poisonous haze blanketing Delhi thickens, air quality turns 'severe' again

The poisonous haze blanketing Delhi thickened on Wednesday with the air quality turning severe again amid stable atmospheric conditions. The national capital's 24-hour average Air Quality Index (AQI), recorded at 4 pm every day, stood at 401. It was 397 on Tuesday. It was 358 on Monday and 218 on Sunday, 220 on Saturday, 279 on Friday and 437 on Thursday. Neighbouring Ghaziabad (378), Gurugram (297), Greater Noida (338), Noida (360) and Faridabad (390) also recorded very poor air quality. 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', 401 and 450 'severe' and above 450 'severe plus'. Delhi's air quality dropped over the last few days despite the state government implementing stringent measures, including a ban on construction work and the entry of diesel-guzzling trucks into the city, to control pollution. According to IQAir, a Swiss company that specialises in air quality ...

Cases of respiratory issues, eye irritation rise in Delhi hospitals

Though Delhi recorded a brief improvement in air quality last week, city hospitals continue to report a rise in the number of patients visiting hospitals for respiratory issues, prolonged coughing, throat infections and eye irritation. The national capital experienced 'very poor' to 'severe' air quality for two weeks starting October 28 with a suffocating haze lingering over the city during the period. Intermittent rain led to a rapid improvement in Delhi's air quality on Friday by over 150 points. However, the respite was short-lived as people flouted the ban on firecrackers on Diwali on Sunday, leading to a jump in pollution levels. Doctors at many government-run and private hospitals said the rise in cases of prolonged coughing, throat infection, eye irritation, nasal discharge and asthma exacerbation continues. Out-patient department (OPD) footfalls may have gone down "very slightly" as people generally avoid going to hospitals during the festive season. "We barely witnessed tw
