A long weekend drive on the highway sounds like a good way to unwind, but the massive, often overloaded trucks and other commercial vehicles belching black-grey smoke can make city roads less pleasant. While commercial vehicles are crucial for the supply of essential goods across cities, they also cause major pollution. In Bengaluru, commercial vehicles make up just 4% of the total vehicle population but contribute a staggering 49% of the city's PM2.5 vehicular emissions. A recent study published by the National Institute of Advanced Studies (NIAS) revealed this fact. Particulate matter from vehicle emissions penetrates deep into the lungs…

Ramesh S, a resident of Perambur, stands at his local bus stop, waiting to start his daily commute. A beat-up Metropolitan Transport Corporation (MTC) bus, painted pink at the front and rear, arrives, emitting visible black smoke from its exhaust. The fumes and unpleasant smell make him cough. In 2023-24, the average age of MTC buses was 9.61 years as opposed to the recommended 9 years. With the addition of a few new buses into the fleet in 2024, this improved to 7.56 years, yet the overall situation remains concerning. The new buses still run on fossil fuel and the…
Read moreAir pollution is a silent epidemic killing people and chipping away at the quality of life the world over. “Not only long-term exposure, but short-term exposure to large quantities of particulate matter can cause an increase in mortality rate. Globally, the death rate due to air pollution is as high as 65 lakhs because of multiple causes, including pollution-related respiratory, cardiac and neuropsychiatric illnesses. Overall they are the outcomes of poor AQI,” explains Dr Snehal Jadhav, the Head of the Department of Respiratory Medicine at R. N Cooper Hospital, Mumbai. This is more than evident in a study published in…
Read moreManvi Goyal, a PR professional, struggled to adapt to Mumbai's polluted air after living in the pristine hills of Kurseong, Darjeeling. “In two years, I have fallen ill several times,” she recounts. She suffers from breathing difficulties and constant dehydration despite drinking water. Manvi is one of many Mumbaikars affected by the city's worsening air quality. On December 30th, the BMC implemented certain sections of Stage IV of the Graded Response Action Plan (GRAP) in parts of Mumbai to improve air quality. Which GRAP IV measures did BMC implement?* Immediate stop to private and public construction in areas where the…
Read moreAs the first light of dawn paints the sky in hues of orange and gold, 17-year-old Ravi steps out of his home. The cool breeze brushes his face as he walks towards the expansive, 150-acre Sembakkam Lake for his morning bath. Millipedes and blanket worms scuttle across the road, their movements as steady as a train on its tracks. A flock of white pelicans glides across the sky as he nears the lake, where a few people fish in the serene waters. After his bath, Ravi returns home to prepare for college. This was M Ravi's experience as a young…
Read moreThe metropolis of Bengaluru, once celebrated as a garden city, is now grappling with the loss of its green spaces, leaving its dwindling lakes as the last line of defence against urban heat. Citizen groups deeply committed to preserving these lakes, have actively engaged in restoration efforts despite challenges like conflicting stakeholder priorities. This is Part 3 of a three-part Citizen Matters explainer series on Bengaluru's lake systems. Part 1 explores Bengaluru's lake system, highlighting its functions and features. Part 2 focuses on the assets of a lake, including core zone assets (ecological assets) and social zone assets (recreational assets). …
Read moreHazy mornings with the air thickened by vehicular smoke during peak-hour traffic are synonymous with Bengaluru winters. The city may have lower PM2.5 levels overall when compared to other mega cities, but high-density traffic corridors and emissions in industrial hubs are causing localised pollution spikes. A November 2024 study by Respirer Living Sciences, analysing PM2.5 pollution levels across ten Indian cities, revealed this data. The study examined AQI information from 13 Continuous Ambient Air Quality Monitoring (CAAQM) sites in Bengaluru that recorded an average of 39 micrograms per cubic metre (µg/m3) of PM2.5 air pollutants in November 2024. This is…
Read moreA lake is much more than a mere water body, it is a complex ecosystem. All those resources or features that make this ecosystem complete and sustainable can be considered lake assets. Assets are generally classified into core zone assets (ecological zone assets) and social zone assets (recreational zone assets). Each serves a set of distinct purposes, supporting the ecological, infrastructural and social functions of a lake system. This is Part 2 of a three-part Citizen Matters explainer series on Bengaluru’s lake systems. Part 1 explores Bengaluru’s lake system, highlighting its functions and features. Part 2 focuses on the assets of a…
Read moreOn December 22nd last year, the Chennai District Collector and the Joint Chief Environmental Engineer of the Tamil Nadu Pollution Control Board (TNPCB) abruptly left Perunthalaivar Kamarajar Maligai in Ennore in the middle of a public hearing. The reason? Chaos and backlash from the local communities of Ennore, who wanted to voice their concerns regarding the Ennore Thermal Power Station (ETPS) Expansion Project. Since the meeting, the unrest has persisted, with many attendees saying they were not allowed to participate, express their views, or raise their concerns. Of the 44 people who spoke at the hearing, only two were women.…
Read moreFor Emil Vinayaraj, a resident of Jayamahal, regular commute has changed. “I have to take a different route now, avoiding Pottery Road where Namma Metro construction is happening. The situation in the area is far from livable right now for residents, as the dust and pollution is just too much,” he says. Emil’s house is close to three new metro stations along the Pink Line — Shivaji Nagar, Cantonment Station and Pottery Town — and residents of this entire area have been facing the brunt of the ongoing work. Similarly, Sri Shanthini, who lives near the Electronic City metro construction…
