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.

Nine dead as massive fire breaks out in residential building in east Delhi
New Delhi (PTI): A fire ripped through a residential building in east Delhi's Vivek Vihar early Sunday, leaving nine people from two families dead, including a toddler, officials said.
The incident was reported at 3.48 am at a four-storey building in Vivek Vihar Phase-I, following which police, fire and disaster management teams rushed to the spot.
The blaze engulfed flats on the second, third and fourth floors of the building, prompting frantic rescue efforts.
With the terrace door locked, the building occupants found it difficult to escape the leaping flames.
Twelve fire tenders were pressed into service, while teams from the Delhi Disaster Management Authority (DDMA), traffic police and local police assisted in evacuation and rescue efforts.
The cause of the fire is yet to be ascertained.
According to the Delhi Fire Service (DFS), nine charred bodies were recovered from different parts of the building. "One body was recovered from the first floor, five from the second floor and three from the staircase which was found locked," a DFS officer said.

Those killed on the second floor were identified as Arvind Jain (60), his wife Anita Jain (58), their son Nishant Jain (35), daughter-in-law Anchal Jain (33) and grandchild Akash Jain.
On the third floor, three members of another family -- Nitin Jain (50), his wife Shailey Jain (48) and their son Samyak Jain (25) -- were found dead.
On the first floor, a woman identified as Shikha Jain (45) was found dead, while her husband Naveen Jain (48) sustained injuries.
A senior police officer said around 10 to 15 people were rescued from the building during the operation. Two persons with minor injuries were shifted to the Guru Teg Bahadur Hospital.
Flames had engulfed large portions of the structure, with thick plumes of smoke spreading across the locality and reducing visibility.
Fire fighters said screams could be heard from those trapped inside the building as they battled for hours to bring the blaze under control.
A firefighter involved in the operation said the intensity of the blaze was significantly higher in the rear portion of the building.
"The fire intensity was higher in the four flats at the rear as compared to the front portion. So far, we have recovered nine bodies and handed them over to Delhi Police. It is difficult to provide details at this stage. The cause of the fire is still under investigation," he said.
He said access constraints worsened the situation.
"Three bodies were found near the terrace level. The access to the roof was locked, and because of this, they could not save their lives. If it had not been locked, they might have survived," he said.
"There is a central staircase which serves as both entry and exit. The rear side gate was covered with a grille, due to which we had to cut it using tools to carry out rescue operations. We deployed five ladders from different sides and also used a turntable ladder vehicle to rescue around 15 people," the firefighter added.
Lieutenant Governor Taranjit Singh Sandhu and Chief Minister Rekha Gupta condoled the loss of lives in the fire tragedy, and said immediate medical assistance and relief are being provided to the affected people.
Delhi BJP president Virendra Sachdeva along with Union Minister of State Harsh Malhotra, local MLA Sanjay Goel, Councillor Pankaj Luthra and BJP Shahdara district president Deepak Gaba, met the bereaved families around 10 am and extended condolences to them on behalf of the ruling party.
The BJP leader said Goel reached the spot within minutes of receiving the information and helped save 18 to 20 people while monitoring the rescue operations.
While talking to reporters, Malhotra described the incident as extremely tragic.
Lauding the prompt response of the fire brigade and police personnel, Malhotra said due to their timely action, around 20 people were rescued.
