Air quality data shows instant values, not comparable to PCB data clarifies Climate Trends

Equipment used is calibrated and the data has 90% match to the data from approved equipment, says the company that released the report.

In response to the statement issued by the Karnataka State Pollution Control Board refuting the findings of the air-quality monitoring work released by Co Media Lab and Climate Trends, the organisations have in turn issued a clarification that the exercise was done to measure peak hour pollution levels in the city for a select amount of time on select routes in the morning as well as in the evening. The objective of the study was to measure and bring to fore the personalised exposure levels one is being subjected to while traveling on busy roads for a few hours every day.

The press note issued on the 19th revealing the data has explicitly mentioned that the results are not comparable to the 24hr averages or the annual regulatory limits as it highlighted Particulate Pollution values for a short period of time only. Moreover, the values released to the press were the instant values for which regulatory limits do not apply and the issued press note emphasised the same.

The Pollution Control Board particularly mentions that the exercise carried out by us is in violation of the monitoring protocols and guidelines issued by the Ministry of Environment, Forests and Climate Change, these are guidelines laid out for measuring ambient air quality and the exercise was aimed at localised, personal exposure levels only. The two are not to be compared. Further, the was study also done to inform the public and citizen leaders who are actively championing the cause of clean air to engage in collective action with administrative bodies to minimise the impacts of pollution before the situation worsens.

This is a press note sent by Aishwarya Sudhir of Climate Trends, on behalf of Climate Trends and Co Media Lab, published here with minimal edits, in the section Message Forward, as a nonprofit public interest message.

Mumbaikars are fighting for their mangroves. Here’s how you can join them

Mumbai is about to face a monumental loss—its mangroves are being cut to build the coastal road. Citizens, however, have not given up the fight to save them.

​“What happens when we remove this natural infrastructure of the city? What happens if it floods? What happens if the air quality (index) goes really high?” asks Pooja Domadia, a member of the Save Mumbai Mangroves campaign. These are questions that many Mumbaikars have as work begins on the Versova-Bhayandar Coastal Road, which is set to affect 45,000 mangrove trees. In March this year, the Supreme Court dismissed a petition challenging the Bombay High Court order to greenlight the cutting of mangroves for the project. Is the SC decision a fatal blow to the movement? The BMC has already begun…

Where are the pollinators in Bengaluru?

Despite the volumes of citizen-generated data on the city's biodiversity, pollinators who sustain the urban ecosystem do not seem to be getting their due attention.

Urban biodiversity is often discussed in terms of tree cover, lakes, or flagship species, but far less attention is paid to pollinators—the insects and birds that quietly sustain urban ecosystems. In Bengaluru, a rapidly urbanising city with a strong culture of citizen science, large volumes of biodiversity data are now being generated by the public. But what does this data tell us about pollinators in the city? This article draws from a data jam hosted by OpenCity in Bengaluru that explored pollinator observations using publicly available, citizen-generated datasets. By analysing long-term observation records and spatial data on land use and…
