Strategies like LPG subsidies and a switch to cleaner cooking fuels could help India become a leader in meeting this challenge, says Dr Maria Neira, director of environment and health at WHO

Emissions could be making rainfall more acidic over past 3 decades: Study

Air pollution could be making rainfall more acidic in cities such as Vishakhapatnam, Allahabad, Mohanbari (Assam), while dust from the Thar could be making rain more alkaline in Jodhpur, Pune and Srinagar, according to an analysis. The study by the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM), Pune, analysed the pH value -- which measures acidity or basicity -- of rainfall of ten cities in India. The data recorded at GAW stations from 1987 to 2021 were analysed. The findings are published by the IMD as a 'met monograph', a comprehensive analysis of a meteorological topic. The study suggests that atmospheric conditions and local emissions can affect the chemistry or pH of rainfall. Both acidic and alkaline rain can have toxic effects, affecting aquatic and plant life, even as the study's authors said "acid rain does not currently pose a major and immediate threat to our region". They attributed acidity in rain in Vizag to emissions

Necessary to tackle pollution: SC refuses to relax ban on firecrackers

The Supreme Court on Thursday refused to relax the ban imposed on the manufacture, storage and sale on firecrackers in Delhi-NCR noting air pollution levels had remained alarming for a considerable time. A bench of Justices Abhay S Oka and Ujjal Bhuyan said a large section of the population worked on streets and was the worst affected by pollution. Not everybody can afford an air purifier at their residence or place of work to fight pollution, the bench said. "Several orders passed by this court during last six months bring on the record the horrible situation with which prevailed in Delhi due to very high levels of air pollution...Right to health is an essential part of Article 21 of the constitution so is the Right to live in a pollution free atmosphere," the court said. Unless the court was satisfied that the pollution due to the "so-called" green crackers was bare minimum, there was no question of reconsidering the previous orders, it added. The top court said the orders passe

Delhi govt tightens pollution control measures; announces EV push

Chief Minister Rekha Gupta announced in the assembly on Wednesday that the Delhi government will introduce a new policy for issuing Pollution Under Control (PUC) certificates to vehicles from other states, in a bid to tackle air pollution. The move comes in response to the Comptroller and Auditor General (CAG) report titled 'Vehicular Air Pollution in Delhi', which flagged lapses in the national capital's pollution control mechanisms. Gupta also announced a significant expansion of electric vehicle (EV) charging infrastructure in Delhi, stating that by 2026, the city will have 48,000 charging points18,000 government-operated and 30,000 semi-private. Additionally, six new air quality monitoring centres will be set up to improve pollution tracking and enforcement.

Pollution biggest challenge, transport sector key contributor: Gadkari

Pollution is India's biggest challenge and the transport sector is a major contributor, Union minister Nitin Gadkari said on Monday, stressing the urgent need to transition from fossil fuels to alternative energy sources. He said India's dependence on fossil fuels is both an economic burden as Rs 22 lakh crore is spent annually on fuel imports and an environmental hazard, making clean energy adoption crucial for the nation's progress. Speaking at the launch of an eco-friendly electric cycle in Thane, the Road Transport & Highways Minister said cycling needs to be promoted as a sustainable urban transport option in view of increasing urbanisation. Gadkari said the rapid growth of India's automobile sector has surpassed Japan to become the third-largest globally since 2014. He said by 2030, India will be the world leader in electric vehicle (EV) production, significantly impacting the global auto market. He credited the sharp decline in lithium-ion battery prices (now at USD 100 per
