A new report from World Resources Institute (WRI) India highlights Indian cities as critical players in the country’s clean energy transition. The report, "How Cities Can Support India’s Energy Transition," underscores that urban centers, which contribute up to 60% of the country's GDP, are uniquely positioned to serve as "natural aggregators of demand" for clean energy and as testing grounds for innovative solutions. The analysis of 10 cities including Bengaluru, Chennai, Delhi, and Indore reveals that local governments are combining national policies with local innovations to accelerate decarbonization efforts. For example, Indore has pioneered a carbon market consultancy service, while Kochi and Pune are leading the way in electrifying public transport. Cities like Surat are also uti...

Your daily dental routine from brushing to flossing is a major source of plastic pollution. A growing body of research shows that the products and materials used for oral hygiene and in dental procedures are shedding billions of microplastic particles that enter our ecosystems and our bodies. Sources of Dental Plastics Microplastics from dental care come from several unexpected sources: • Toothpaste: While many countries have banned plastic microbeads in toothpaste, many modern products still contain microplastic particles. • Toothbrushes and Floss: The nylon bristles of toothbrushes shed tiny fragments during use, and most dental floss is made from non-biodegradable materials like nylon or Teflon that also shed particles. These fragments are washed down the drain, where they c...

Rural communities facing mounting environmental pressures like land fragmentation and climate change can build resilience by combining traditional ecological knowledge with modern management strategies. A new report, based on two studies from rural China and semi-arid Iran, reveals that the key to survival lies in uniting modern science with local wisdom. The studies show how larger, more consolidated land plots and the integration of traditional ecological knowledge with healthy habitats can lead to more productive and sustainable communities and ecosystems. Lessons from China: Scale and Social Support A study in Jiangxi Province, China, investigated the Forestland Management Efficiency (FME) of 505 rural households. The research challenged a common assumption by finding that famili...

As India urban centers grapple with a monumental waste problem a critical debate is emerging over the role of privatization in sanitation. While outsourcing promises efficiency through technology and performance-based contracts it often comes at a steep cost for the millions of sanitation workers who form the backbone of the system. According to a report from Outlook Business, urban India generates approximately 170,000 tonnes of municipal solid waste every day, and while nearly all of it is collected, less than half is scientifically processed. In cities like Chennai, the move to privatize waste management has sparked strikes and protests from workers fearing brutal pay cuts and job insecurity. This tension highlights a central question: Can privatization work without deepening inequal...

SYDNEY – In a significant victory for wildlife conservation, Australia has approved a new vaccine to protect its koala population from chlamydia. The disease is a major threat to the endangered marsupial, causing widespread illness, infertility, and death. Developed over a decade by a research team at the University of the Sunshine Coast, the vaccine is a critical tool in the fight to save koalas, which are facing severe population decline. How the Vaccine Works The single-dose vaccine, created by Professor Peter Timms's team, is designed to combat chlamydia in three ways: • It reduces the chance of a koala becoming infected. • It prevents the disease from progressing in already infected animals. • It can even reverse symptoms in some cases. Clinical trials have shown ...

NEW DELHI – A groundbreaking study by Indian scientists has revealed a direct connection between the ancient formation of Antarctic ice sheets and the early evolution of the Indian monsoon system. Published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology, the findings show that a major climatic event on one side of the planet had a profound ripple effect on the other, shaping the climate that now supports a billion people. Fossil Leaves Tell a 34-Million-Year-Old Story The discovery stems from the analysis of well-preserved fossil leaves found in the Laisong Formation of Nagaland. Dating back roughly 34 million years ago to the Eocene-Oligocene transition, the fossils indicated that the region once had a warm, wet, and tropical climate. Scientists from the Birbal ...

NEW DELHI – A new study by Indian researchers has found high concentrations of toxic mercury in the air of India's capital city, Delhi. According to the research, published in the journal Air Quality, Atmosphere & Health, Delhi's air contains an average of 6.9 nanograms of mercury per cubic meter, a level significantly higher than the global average for the Northern Hemisphere (1.7 ng/m³) and the Southern Hemisphere (1.3 ng/m³). The study, conducted by scientists from the Indian Institute of Tropical Meteorology (IITM), Pune, analyzed data on gaseous elemental mercury (GEM) from 2018 to 2024. It found that 72% to 92% of the mercury emissions were linked to human activities, primarily from the combustion of fossil fuels, industrial operations, and vehicular emissions. While the st...

The Kerala State Beverages Corporation Limited (Bevco) is rolling out a new plastic bottle return scheme in a pilot project aimed at promoting responsible waste disposal. The initiative, which launched on Wednesday, is a collaboration with Clean Kerala Company and is starting with 20 Bevco outlets—10 each in Thiruvananthapuram and Kannur. Under the new scheme, customers will be charged a refundable deposit of ₹20 for each QR-coded plastic liquor bottle. The deposit will be returned when the customer brings the empty bottle back to the same outlet with the label intact. According to Harshitha Attaluri, Managing Director of Bevco, this is a step towards sustainable retail practices. The labels, which were developed with assistance from the Centre for Development of Imaging Technology (C-D...

NEW DELHI – The National Green Tribunal (NGT) has raised serious objections to the ongoing practice of discharging domestic and industrial waste into stormwater drains in Varanasi. During a hearing on August 29, the tribunal stated that these drains are meant exclusively for rainwater and that connecting them to sewage treatment plants (STPs) could lead to the plants being overloaded, particularly during the monsoon season. The case focuses on the continued discharge of untreated waste into the Ganga River. While the Uttar Pradesh government sought more time to submit its action plan, the NGT, led by Chairman Justice Prakash Shrivastava and expert member Ishwar Singh, expressed its concerns directly to the National Mission for Clean Ganga (NMCG). According to reports, Varanasi has 48...

CHENNAI – Residents of high-rises along Chennai's Old Mahabalipuram Road (OMR) are once again facing a severe air pollution problem, with a pungent gas returning to localities like Kelambakkam, Siruseri, Padur, and Navalur. The foul odor, which had briefly subsided, has resurfaced in the last month, causing health issues such as throat irritation, coughing, nausea, and eye and skin irritation. This is not the first time residents have dealt with the issue. In May 2025, officials from the Tamil Nadu Pollution Control Board (TNPCB) conducted a field study and identified a pharmaceutical company in the SIDCO industrial estate in Alathur as the source of a volatile organic compound (VOC). A recent sensor reading by TNPCB staff reportedly detected VOC levels between 0.5-0.7 ppm, though offic...
