City air improves but PM10 remains high – The Times of India


Kolkata: A four-year analysis by Respirer Living Sciences revealed that while Kolkata has made steady progress in reducing PM10 pollution since 2021, air quality in the city remained hazardous throughout the year. This defies the common belief that summer offers temporary relief from pollution.
The study, based on data from AtlasAQ, Respirer’s air quality platform, highlights that Kolkata’s PM10 levels declined from 111.5 µg/m³ in 2021 to 91.6 µg/m³ in 2024. While this downward trend is encouraging, every annual average still significantly exceeds the National Ambient Air Quality Standards (NAAQS) limit of 60 µg/m³ — even during summer months, which typically witness cleaner air due to atmospheric dispersion.
“Kolkata’s trend is moving in the right direction but we cannot mistake marginal progress for clean air. PM10 levels continue to breach safety limits in every season. This highlights the need for deeper urban reforms and sustained enforcement,” said Ronak Sutaria, founder and CEO of Respirer Living Sciences.
Detailed station-level analysis underscores the widespread nature of Kolkata’s air quality challenges. The Rabindra Bharati University station, which once recorded PM10 levels as high as 146.4 µg/m³ in 2021, showed the most substantial improvement, dropping to 86.7 µg/m³ in 2024. However, several key locations, including Victoria Memorial (102.9 µg/m³), Fort William (100.2 µg/m³), and Jadavpur (93.8 µg/m³), remain well above the safe threshold.
Even residential neighbourhoods like Rabindra Sarobar (71.0 µg/m³) and Ballygunge (96.8 µg/m³) reported PM10 levels far exceeding the national safety limit, emphasising that no part of the city is spared from chronic particulate exposure.
While Kolkata’s figures remain alarming, its consistent downward trend places it among a small group of Indian cities — including Mumbai and Hyderabad — that showed improvement in PM10 levels over the 2021-2024 period. This is likely the result of localised interventions, such as stricter emission controls, green initiatives, and public transportation enhancements.
In contrast, cities like Delhi, Patna, Chandigarh, and Lucknow continue to grapple with some of the highest PM10 concentrations in the country, with Delhi consistently averaging over 200 µg/m³ each year. Seasonal spikes during winter months — driven by temperature inversions and biomass burning — further compound these challenges.
The report urges policymakers to build on Kolkata’s momentum by implementing stronger emission regulations, particularly around high-traffic corridors and construction zones. It also recommends expanding public transport networks and continuing real-time air quality monitoring to ensure sustained progress.
“Air quality must be treated as a core urban governance issue. With the right investments and community engagement, cities like Kolkata can turn the tide. But the time to act is now,” the report said.
As Kolkata inches closer to cleaner skies, the message is clear: progress is possible, but only through unwavering commitment, systemic change, and collective effort.

Kochi Water Metro sails into third year with patronage of 4 million commuters

Kochi Water Metro sails into third year with  patronage of 4 million commuters


Kochi Water Metro ferries berthed at the High Court terminal. As it steps into its third year, the Water Metro is set to expand its operations both within Kerala and across India.

The fleet of 19 air conditioned hybrid-electric Water Metro ferries that are operating in Kochi transported a total of 4 million commuters across 10 terminals in the Greater Kochi area, during the past two years.

They were from among the twenty-three 100-passenger ferries for which Kochi Metro Rail Ltd (KMRL) had placed an order with Cochin Shipyard. This first-of-its-kind water transport system in India that aims to introduce 78 ferries in the Greater Kochi area in a phased manner is being implemented by the Kerala government. It was officially launched on April 25, 2023.

As it steps into its third year, the Water Metro is set to expand its operations both within Kerala and across India. The project had won the Gussies Electric Boat Award-2022 in the commercial ferry category and the Skoch Award for excellence in offering services to the public in the transport sector. The Union government had plans to probe the feasibility of replicating the model in 21 locations across the country, said a KMRL release.

The agency’s MD, Loknath Behera, hoped that the system of water transport would bring in sustainability and affordability in public transport and help decongest roads.

A feasibility study to implement the Water Metro project in Mumbai has been submitted to the Maharashtra government by KMRL. The agency was also asked to conduct feasibility studies to implement the Water Metro system in 21 urban centers across 11 States and two Union Territories, it said.

Kol-based mobile games startup to get Rs 1.2cr from Krafton | Kolkata News – The Times of India


Sarthak.G: A city-based mobile games startup has been selected for the Krafton India Gaming Incubator (KIGI) and will receive up to Rs1.2 crore in financial support and technical assistance for one year. Krafton, a South Korean mobile games provider, included Advaita Interactive among six Indian companies in the second cohort of KIGI.
The startup, founded by Judhajit Sarkar, is developing Inspectorium, a detective game set in a Steampunk-inspired version of Victorian-era Kolkata. With episodic cases, real-time AI-powered interrogations and immersive puzzle-solving, the game would be released across mobile, PC and VR platforms by next year, said Anuj Sahani, head of the KIGI programme.
“There is a common perception that not much e-sports development happens in Kolkata. Advaita Interactive has shattered that perception. KIGI has expanded its cohort from four to six startups, extending its reach to emerging gaming hubs like Kolkata and Madurai, among others. We will provide funding to the startup over the next year along with technological support,” said Sahani.

NEUFC hit MSC for a six, set up quarters date with JFC | Bhubaneswar News – The Times of India

NEUFC hit MSC for a six, set up quarters date with JFC | Bhubaneswar News – The Times of India


Notwithstanding the heartbreak of the ISL playoffs, the Highlanders fans got rights for the largest cheer in the pre-quarterfinals of Kalinga Super Cup with their star striker Alaaeddine Ajaraie scoring his first-ever hat-trick for the club as North East United FC routed Mohammedan Sporting 6-0 on a hot and humid afternoon in Bhubaneswar.
The treble from Ajaraie (18′, 57′, 90+3′), coupled with the opener from Jithin MS (3′) and strikes from Nestor Albiach (42′) and Guillermo Fernandez (66′) ensured that Juan Pedro Benali’s men romped to the quarterfinals with a show of confidence at Kalinga Stadium on Thursday.
It was a disappointing end to Mohammedan’s campaign that got very little time for preparation with Mehrajuddin Wadoo’s wards reaching the Odisha capital just three days back.
Later in the evening, a strong Jamshedpur FC contingent set up a quarterfinal with Benali’s NEUFC by beating Hyderabad FC 2-0 in the second match of the day.
Despite boasting a squad with all six foreigners, Khalid Jamil’s men faced a tough contest from the all-Indian Hyderabad side that stayed at the back to curb all of Jamshedpur’s efforts for a breakthrough.
The deadlock was broken just before the break when Ashutosh Mehta was fouled inside the box by Manoj Mohammed and Javier Siverio made no mistake in sending goalkeeper Arshdeep Singh the other way to convert from the spot.
It was a delightful move started by Siverio outside the box that led to a pass to Jordan Murray, who sent a low cross to an onrushing Stephen Eze who guided it into the goal. Replays, however, showed that the Nigerian was offside.
While NEUFC’s first and third goals were results of serious defensive lapses on the part of their rivals with an unmarked Jithin tapping in an Albiach cross inside the box in the third minute and the Spaniard turning scorer after another defensive error just before half-time, their second was a testament to the skill of Moroccan Ajaraie in front of goal.
The change of ends did not change the course of the game as the ISL Golden Boot winner powered in a rebound near goalmouth in the 57th minute and played provider to Spaniard Fernanadez nine minutes later.
Ajaraie completed his hat-trick from the spot after he was brought down inside the box in injury time.
