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

Ensure ban of private polluting buses in Delhi: AAP govt to authorities

Delhi Environment Minister Gopal Rai directed the transport department on Friday to conduct a special drive to prevent the entry of private polluting buses into the capital. The minister reviewed the implementation of air pollution control measures at the Sarai Kale Interstate Bus Terminal and found buses from other states flouting the ban imposed on BS IV diesel vehicles under the Centre's Graded Response Action Plan. "We have found that private buses from other states have been violating the ban and have directed the transport department to run a special drive to check the entry of such vehicles into Delhi," he told reporters. Citing experts' views, Rai said that a slight improvement in meteorological conditions might lead to marginal relief but urged agencies to remain alert. Strict restrictions, including a ban on construction work and the entry of polluting trucks into the capital, under the final stage (Stage IV) of the Centre's air pollution control plan, known as the Graded

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.

Rai had previously reprimanded the departments concerned for their negligence in executing the air pollution control plan and urged them to establish a monitoring mechanism for overseeing the teams responsible for enforcing anti-air pollution measures. Delhi's air quality fluctuated between the 'very poor' and 'severe' categories on Thursday due to unfavourable meteorological conditions hindering the dispersion of pollutants.
