The clean air gap: What India knows it needs vs what it’s actually doing
Despite India’s claims of progress in reducing air pollution through the National Clean Air Programme, the country is far behind targets and even ranked among 10 most polluted nations last year. But this is a problem compounded by many unimplemented recommendations – made by government committees, non-government organisations, and research institutions over the years. For example, a report by the Parliamentary Standing Committee on Science and Technology, Environment, Forests and Climate change had in 2023 recommended the Centre to revisit its monitoring framework for NCAP. It had highlighted the need for qualitative apart from quantitative data, and the inclusion of public experience and social audit as parameters. But those parameters are yet to be revised. Newslaundry audited several such recommendations, most of them made after 2022, and found that many are yet to be implemented. #1: Air quality standards status quo In 2022, CSIR-National Institute of Science Communication and Policy Research, under the aegis of the Union Ministry of Science and Technology, had suggested a stringent revision of the National Ambient Air Quality Standards. But they remain unchanged since 2009 and are much more lenient as compared to the WHO air quality standards which were revised in 2021 – for example, the PM2.5 standard under NAAQS is 40 µg/m3 while the WHO wants it limited to 5µg/m³. The same paper also recommended expanding the scope of the monitoring stations in rural areas. However, the Central Pollution Control Board’s website only shows a rural network of 26 stations in 26 villages as of November 2024. The number stood at 26 even in 2020, as per a response to a Lok Sabha query, suggesting a slow pace of expansion. Sensor ambient air quality monitors are absent. They were recommended in a 2022 report by IIT Delhi’s Centre for Atmospheric Sciences and Centre of Excellence for Research on Clean Air, and in 2023 by private thinktank Centre for Science and Environment Analysis. Between November 2020 and May 2021, a total of 40 SAAQMs, manufactured by four Indian companies, were installed alongside the existing continuous ambient air quality monitoring stations under a pilot project in Maharashtra. This project and SAAQMs were rejected in 2023. Last year, a report by IIT Delhi’s TRIP-Centre had pointed out that most cities lacked the minimum recommended number of monitoring stations. Of 562 CAAQM stations across the country as per the CPCB website, only 473 are fully operational, according to the Central Control Room for Air Quality Management. And 186 cities have just one monitoring station each to themselves. In 2019, the Fifteenth Financial Commission had recommended monitoring aerosol optical depth – a measure of aerosols such as smoke and sea salt within a column of air. In 2023, Union Environment Minister Ashwini Kumar Chaubey told the Lok Sabha that the AOD data cannot be used “for regulatory purposes”.
