NGT issues notice to Centre on persistent air pollution crisis in Delhi

The National Green Tribunal has sought a response from the Centre on the "persistent air pollution crisis" in the national capital. The NGT was hearing the matter where it had taken suo motu (on its own) cognisance of a media report based on a study about the reasons for air pollution being emissions from thermal plants and the prevailing weather conditions. In an order passed on November 27, a bench of NGT Chairperson Justice Prakash Shrivastava said, "As per the article, a recent study by the Centre for Research on Energy and Clean Air (CREA) has revealed that thermal power plants in the region are responsible for emitting 16 times more air pollution than the pollution caused by stubble burning." The bench also comprising judicial member Justice Arun Kumar Tyagi and expert member A Senthil Vel said that at present, Delhi was facing a "persistent air pollution crisis, with the Air Quality Index (AQI) (recently) reaching an alarming 488, falling under the severe plus category."

Stubble burning among causes of Delhi pollution: Officials tell House panel

Stubble burning in Punjab and Haryana is among the main reasons for air pollution in Delhi-NCR and several steps are being taken to encourage farmers to use paddy residue for animal feed and industrial purposes, a top Union environment ministry official told parliamentarians on Wednesday. Ministry of Environment, Forest and Climate Change Secretary Leena Nandan, while making a presentation on air pollution in Delhi-NCR before the Parliamentary Standing Committee on Science and Technology, Environment, Forests and Climate Change, also took suggestions from the MPs to reduce air and water pollution. Sources said she told the MPs that the government was trying to promote the use of Basmati rice, whose residue is used for animal feed, besides using the paddy straw for industrial purposes. She also listed vehicular emission as another reason for air pollution and said the government was making efforts to promote e-vehicles in the national capital.

Delhi's Nov PM 2.5 level reaches highest monthly avg in 8 yrs despite Grap

Delhi's PM2.5 level in November reached its highest monthly average in eight years despite the implementation of GRAP measures, a recent report has revealed. A report by the Centre for Research on Energy and Clean Air (CREA) highlighted that Delhi's PM2.5 concentration soared to an average of 249 micrograms per cubic metre in November -- the highest since 2017 -- despite enforcement of the Graded Response Action Plan (GRAP) and a decrease in stubble burning incidents. In November 2016, the average PM2.5 level was recorded at 254 micrograms per cubic metre, the highest November reading, followed by 249 micrograms per cubic metre this year. PM2.5 are fine particles with a diameter of 2.5 micrometres or less, about the width of a human hair. These are so small that these can penetrate deep into the lungs and even enter the bloodstream, posing significant health risks. A report by the Centre for Research on Energy and Clean Air (CREA) highlighted that Delhi's PM2.5 concentration soared

SC refuses to relax Grap-4 restrictions unless AQI shows 'downward trend'

The Supreme Court on Monday refused to relax emergency measures under Stage 4 of the Graded Response Action Plan (GRAP) dealing with air pollution in the national capital till it noticed a downward trend in the AQI level. A bench of Justices Abhay S Oka and Augustine George Masih further sought the presence of the chief secretaries of NCR states to appear through video-conferencing to inform it whether or not any compensation was paid to the construction workers who were without work owing to the restrictions. Notably, there has to be a downward trend before the Supreme Court relaxes GRAP 4 restrictions. The bench said the chief secretaries of NCR states including Delhi, Haryana, UP and Rajasthan will have to appear through video-conferencing at 3.30pm on December 5. "There is hardly any implementation of stage 4 of GRAP to deal with air pollution in the national capital, remarked the bench, questioning the Delhi government on the number of officers deployed by it to implement the

Winters of despair: How Delhi's pollution curbs affect construction workers

"When they stop our work, we don't just lose the wages. It's the food on our plates and the little we try to save for our children's future," says Raju Singh, a mason from Bihar. He was one of thousands of migrant and local construction workers rendered jobless following the November 11 ban on constructions, prompted by the Delhi-NCR's air quality plunging to hazardous levels. More such bans are likely to follow throughout the winter. While that is good news for the city's residents, the story is different for these construction workers. "Even though working in the polluted air makes it hard for us to breathe, I would rather work than sit idle," Raju Singh says, describing the crushing blow the restrictions have on his finances. These trysts with work stoppages have become an annual affair for him, and hundreds of others like him. The Commission for Air Quality Management in the National Capital Region and Adjoining Areas (CAQM) -- a statutory body responsible for formulating ...
