KSPCB to evaluate city action plans for improving Bengaluru’s air quality based on latest studies
Bengaluru: The Karnataka State Pollution Control Board (KSPCB) on Friday said they will be analyzing their city action plans using two recent air pollution source assessment studies in their efforts to improve air quality across the state.
While Bengaluru's deteriorating air quality is a cause for concern, studies released by the Center for Study of Science, Technology, and Policy (CSTEP) have revealed that measures targeted at polluting sources can help lower pollution levels.
According to CSTEP’s research released earlier this year, the transportation industry is the largest source (40–51%) of particulate matter, followed by road dust resuspension (17–51%). Construction dust, household gasoline, and diesel generators are among the other polluting industries.
Air has suspended particulate matter (PM) of different sizes. Many of these are a complex mixture of dust, pollen, soot, and smoke and they are hazardous. Of this, PM 2.5 is the smaller kind, with a diameter, of not more than 2.5 micrometers (fine particles). PM2.5 is considered to have a very significant health impact as it can stay in the air for days or weeks, and is small enough to invade the lung airways.
The studies, titled "Emission Inventory and Pollution Reduction Strategies for Bengaluru" and "Identification of Polluting Sources for Bengaluru," identified polluting sources/activities or hotspots for the city, which has been a major concern for air pollution regulators and policymakers.
On Friday, April 29, 2022, CSTEP held data dissemination and capacity building event for over 50 Karnataka government officials at Shangri-La, Bengaluru, where findings of the two studies were shared to ensure the implementation of solutions from the studies as well as empower government officials to make informed decisions.
At the workshop, Dr Shanth A. Thimmaiah, Chairman, KSPCB reflected on the need for micro action plans that will help pollution control boards to take effective, result-oriented action toward improving air quality. “The event is an opportunity to evaluate our work. CSTEP’s reports will be used as a base for studying and making clean air action plans for three other non-attainment cities through a Plan-Do-Check-Act approach,” he said.
Shri Vijay Mohan Raj, IFS, Principal Secretary, Ecology and Environment Department, Government of Karnataka, highlighted the need for air guilt—the guilt that comes from knowing that we are contributing to air pollution (and how)—to be felt by all and drive our actions. “To do this, data needs to be presented in simple formats that could be understood even by children. I hope that such reports can bring about last-mile changes to improve air quality,” he said.
CSTEP’s study findings revealed that Bengaluru can see possible concentration reductions of approximately 26.5%, ~13.5%, and ~9.6%, respectively, for high-, medium-, and low-emission reduction scenarios (measures clubbed with varying levels of compliance) for both PM10 and PM2.5 by 2024.
Key measures considered under the scenarios were improvement in public transportation infrastructure, diesel particulate filter installation in trucks, and a strict blanket ban on open waste burning. “Considering Bengaluru’s status as a non-attainment city, conducting a scientific assessment through source apportionment and emission inventory was crucial towards preparing efficient strategies,” said Dr. Pratima Singh, Research Scientist at CSTEP who led the study.
CSTEP—as an Institute of Repute under the National Clean Air Programme—is working with the KSPCB and Bruhat Bengaluru Mahanagara Palike (BBMP) to help implement the recommendations. By training state government officials to use scientific methods to assess air quality through this event, CSTEP hopes to enhance the quality and effectiveness of policy decisions.
Ms Puja Tewary, India Coordinator, Climate and Environment Programs, Bloomberg Philanthropies, said, “Scientific evidence highlighted in the report could inform both line departments and KSPCB in preparing city micro action plans.” She reiterated that mutual collaborations among organizations are essential.
A ‘meaningful’ action plan could be prepared as a result of CSTEP’s studies, said Shri Gaurav Gupta, IAS, Chief Commissioner, Bruhat Bengaluru Mahanagara Palike (BBMP). “The studies highlight vehicular pollution and road dust as the main issues for Bengaluru. We are working on these sectors. Bengaluru is among the fastest-growing cities, and this is the main reason for air pollution,” he added.

Azerbaijani airliner with 67 people onboard crashes in Kazakhstan leaving 32 survivors
Moscow, Dec 25: An Azerbaijani airliner with 67 people onboard crashed Wednesday in the Kazakhstani city of Aktau, leaving at least 32 survivors, according to officials. More than 30 people are likely dead.
Kazakhstan's Emergency Ministry said in a Telegram statement that those on board included five crew. At least 29 have been hospitalized, the ministry told Russia's state news agency RIA Novosti.
Russian news agency Interfax quoted medical workers as saying that four bodies have been recovered and emergency workers at the scene as saying that both pilots, according to a preliminary assessment, died in the crash.
The Embraer 190 aircraft made an emergency landing 3 km from the city, Azerbaijan Airlines said earlier.
Kazakhstan's Emergency Ministry initially said 25 people survived the crash, later revising that number to 27, 28, and then 29 as the search and rescue operation continued at the site of the crash, bringing the supposed death toll down.
Prosecutor General's Office in Azerbaijan later reported that at least 32 people survived the crash, adding that the number wasn't final.
The number of survivors could mean that over 30 people may be dead.
The plane was originally scheduled to travel from the Azerbaijani capital of Baku to the Russian city of Grozny in the North Caucasus. According to Azerbaijan Airlines, 37 passengers were Azerbaijani citizens. There were also 16 Russian nationals, six Kazakhstani and three Kyrgyzstani citizens, it said.
RIA Novosti quoted Russia's civil aviation authority, Rosaviatsia, as saying that preliminary information showed that the pilot had chosen to divert to Aktau after a bird strike on the aircraft led to “an emergency situation on board”.
Mobile phone footage circulating online appeared to show the aircraft making a steep descent before smashing into the ground in a fireball. Other footage showed part of its fuselage ripped away from the wings and the rest of the aircraft, lying upside in the grass. The footage corresponded to the plane's colors and its registration number.
Some of the videos posted on social media showed survivors dragging fellow passengers away from the wreckage of the plane.
Flight-tracking data from FlightRadar24.com showed the aircraft making what appeared to be a figure-right once nearing the airport in Aktau, its altitude moving up and down substantially over the last minutes of the flight before impacting the ground.
FlightRadar24 separately said in an online post that the aircraft had faced “strong GPS jamming” which “made the aircraft transmit bad ADS-B data”, referring to the information that allows flight-tracking websites to follow planes in flight. Russia has been blamed in the past for jamming GPS transmissions in the wider region.
Embraer did not immediately respond to a request for comment early Wednesday morning. In a statement, Azerbaijan Airlines said it would keep members of the public updated and changed its social media banners to solid black.
Azerbaijan's state news agency, Azertac, said that an official delegation consisting of Azerbaijan's emergency situations minister, the country's deputy general prosecutor, and the vice president of Azerbaijan Airlines had been dispatched to Aktau to conduct an “on-site investigation”.
Azerbaijani President Ilham Aliyev, who had been traveling to St Petersburg, returned to Azerbaijan on hearing news of the crash, the president's press service said. Aliyev was due to attend an informal meeting of leaders of Commonwealth of Independent States, a bloc of former Soviet countries founded after the collapse of the Soviet Union.
Aliyev expressed his condolences to the families of the victims in a statement on social media. “It is with deep sadness that I express my condolences to the families of the victims and wish a speedy recovery to those injured,” he wrote.
Russian President Vladimir Putin spoke to Aliyev on the phone and expressed his condolences, Kremlin spokesman Dmitry Peskov told reporters.
Both Kazakhstani and Azerbaijani authorities were investigating the crash. Embraer told The Associated Press in a statement that the company is “ready to assist all relevant authorities.”
