Death by air pollution A Greenpeace Southeast Asia report on Thursday estimated that Bengaluru recorded 12,000 avoidable deaths due to PM 2.5 air pollution in 2020. The city fared better than Delhi and Mumbai, but worse than Chennai, Hyderabad, and Lucknow. The ‘Cost Estimator’ online tool estimated the real-time health impact and economic cost from fine particulate matter (PM 2.5), using real-time ground-level PM 2.5 measurements collated in IQAir’s database. Apart from waste burning, construction, industries, and DG sets, the fossil-fuelled transport sector was the key emission source. Polluted air increases the likelihood of deaths owing to cancer and stroke,…

Bengaluru is today synonymous with traffic and air pollution. Among Indian cities, Bengaluru ranked third in overall emissions and energy consumption in a recent survey by CSE (Centre for Science and Environment). PM2.5 and PM10 emissions contribute to much of the air pollution in the city, and 60-70% of these emissions originate from vehicles and road dust. Considering the high contribution of vehicle emissions to air pollution, the Karnataka Electric Vehicle and Energy Storage Policy is a welcome move. The policy targets 100% electric mobility by 2030 for certain vehicle segments — auto rickshaws, cabs, corporate fleets, school buses, public transport…

On a hot afternoon, Sachin (name changed on request) stands in the centre of a busy junction in the heart of the city. He’s wearing the iconic white uniform, a hat and black leather shoes. He also has two Mi AirPOP PM2.5 Anti-Pollution masks, which he wears during peak hours. “I can’t keep wearing the mask continuously for 8 hours, I can’t use the whistle and it’s uncomfortable”, he says. Traffic teems past him on both sides of the road, as he uses hand-signalling to direct vehicles.  He has been standing since 7 a.m. in the morning and will continue…

There are indications that air pollution is contributing to premature deaths from cardiovascular disease in people under 40, said Dr Rahul Patil, interventional cardiologist at the Jayadeva Institute of Cardiovascular Sciences and Research. Dr Patil was speaking at the India Clean Air Summit 2019 (ICAS19). “Inhalation of particulate matter is leading to thickening of blood, with patients often showing clinical behaviours of a smoker although they are non-smokers,” he said. ICAS19 was hosted by the Centre for Air Pollution Studies, CSTEP, in partnership with the Karnataka State Pollution Control Board (KSPCB) and the state government's Department of Forest, Ecology and…

Globally, air pollution reduces life expectancy by one year and eight months, on average. This loss ranks just below smoking, but above unsafe drinking water and lung cancer (State of Global Air report, 2019). Emissions from increasing vehicular population, and residential and commercial activities, are polluting even the air far from the source, and affecting the health of millions of people. Lack of scientific methods to assess pollution, inadequate data and analysis have further hampered policy efforts to improve air quality in Indian cities. The Center for Study of Science, Technology and Policy (CSTEP), a leading research-based Indian think tank,…

This article is part of a special series: Air Quality in our Cities "Even though a mechanised sweeper is being used along the arterial roads of Mahadevapura Zone, the roads accumulate dust in no time, and it feels like they have not been cleaned in the first place", says Anu Govind, a volunteer with the citizen's group Whitefield Rising (WR). Dust is something we see everyday, but never think about controlling it outside our homes. A study done in 2010 titled Air Quality Monitoring, Emission Inventory and Source Appropriation Study for Indian Cities, found that road dust accounts for 20 percent…

This article is part of a special series: Air Quality in our Cities Five out of 15 Bengaluru Metropolitan Transport Corporation (BMTC) buses that the Regional Transport Office officials from the Transport Department had randomly inspected had failed the emission tests.That was in 2016. Recent reports said that BMTC bus breakdowns have considerably reduced compared to previous years due to an improvement in their maintenance procedures. Would that also mean that there is an improvement in BMTC buses following emission standards? What are the measures taken by BMTC to ensure that their buses follow emission norms? What are the external measures…

This article is part of a special series: Air Quality in our Cities The drastic rise in air pollution levels in Indian cities over the years has been a cause of extreme concern, especially after the World Health Organization (WHO) pointed out that several Indian cities were part of the top 20 most polluted cities in terms of PM 2.5 levels. As part of a recent study by Aishwarya Sudhir ( supported by Co-Media Lab and Climate Trends), titled Bengaluru’s rising Air Quality Crisis, air pollution levels were tested for PM 2.5 (atmospheric particulate matter with diameter less that 2.5…

The Karnataka State Pollution Control Board has issued the following rejoinder on 22nd February to the press release by Climate Trends, on the air quality data monitoring exercise, published on 19th February. [Update] On 23rd February, the team behind the study, Climate Trends and Co Media Lab issued an addendum to clarify the points made in KSPCB's statement below.  On 21st February 2018, Co- Media Lab and Climate Trends have released the report on air quality of Bengaluru City, where it is reported that there are huge gaps in the KSPCB data on the smaller particulate matter ( PM 2.5).…

Bengaluru's air quality crisis, unlike that in the cities of the north, is a silent one; most online ambient stations which provide information to the public paint a fairly clean picture of the city’s air, though most of its citizens feel otherwise. In an effort to understand the palpable pollution levels in the air we breathe, in comparison to the ambient data being generated by the KSPCB, Co Media Lab and Climate Trends carried out a 7-day air quality monitoring exercise with the help of a low-cost monitor used to measure personalised exposure levels. The activity was spread over a…
