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.

Beyond the parks and gardens, Bengaluru’s ‘wasteland’ ecosystems call for protection

Open Natural Ecosystems in Bengaluru harbour rich biodiversity. Take a look at what they hold and what we risk losing to unchecked development.

When we discuss urban nature, we often forget about real natural habitats. In Bengaluru, widely called the Garden City, most talks about urban nature focus on landscaped parks, roadside trees, and manicured gardens; in other words, artificial ecosystems designed for looks and human comfort. As lay citizens, we usually notice only such nature as we see around our homes, workplaces or other areas we generally pass by. While these places do have some ecological value, they mostly support a few highly adaptable species. This has strong negative implications for native flora and fauna that depend on open scrublands, grasslands, rocky…

The wild in the city: What citizen scientists tell us about Bengaluru’s biodiversity

Spatial and temporal biodiversity patterns, as observed by citizen scientists in the city during 2016-2025, were studied at a datajam in December 2025.

Imagine you’re out on a morning walk, phone in hand, when you spot a butterfly you’ve never seen before. You snap a photo, log it into a citizen science app, and voila! You’ve just contributed to crucial biodiversity monitoring. This isn’t just a hobby; it’s part of a global movement where ordinary people collect, record, and sometimes analyse data about plants, animals, and ecosystems. Citizen science stretches the reach of ecological research. Every observation adds to unique longitudinal datasets that reveal phenology — periodic events in the life cycle of a species — along with species distribution shifts and population…
