An analysis by the environmental think tank, Centre for Science and Environment, reported “barely any difference” in trends in particulate matter pollution (PM2.5) between the group of cities under the National Clean Air Programme (NCAP) and those outside its ambit.
The covers 132 of India’s most polluted or so-called non-attainment cities. This is defined as a city whose air quality did not meet the national ambient air quality standards of 2011 to 2015. The NCAP launched in 2019 aims to bring a 20%-30% reduction in pollution levels from PM2.5 and PM10 particles by 2024, using 2017 pollution levels as a base.
Cities are required to quantify improvement starting 2020-21, which requires 15% and more reduction in the annual average PM10 concentration and a concurrent increase in “good air” days to at least 200. Anything fewer will be considered ‘low’ and the funding consequently reduced.
