India recorded a major 19.3% drop in particulate pollution in 2022 in comparison with 2021, the second-highest discount on the planet after Bangladesh, including a median of 51 days to the life expectancy of each citizen, based on a brand new report.
The annual report, “Air High quality Life Index” 2024, by the Power Coverage Institute on the College of Chicago (EPIC) additionally mentioned that Indians are more likely to lose 3.6 years of life expectancy if the nation fails to satisfy the World Well being Group’s annual PM2.5 focus customary of 5 micrograms per cubic metre.
The researchers attributed the decline in particulate ranges in India and different South Asian nations primarily to beneficial meteorological situations and a decreased variety of thermal inversions — when a layer of heat air traps cooler air close to the bottom, inflicting air pollution to construct up.
PM2.5 concentrations in India in 2022 had been round 9 micrograms per cubic metre, 19.3% decrease than 2021.
Essentially the most important declines had been noticed in Purulia and Bankura districts of West Bengal, adopted by Dhanbad, Purbi, Paschim Singhbhum, Paschim Medinipur and Bokaro districts in Jharkhand. In every of those districts, PM2.5 concentrations dropped by over 20 micrograms per cubic metre.
The report mentioned that the northern plains, probably the most polluted area in India, noticed a 17.2% discount in particulate ranges in 2022 in comparison with 2021.
Nevertheless, regardless of this enchancment, the common resident on this area remains to be more likely to lose about 5.4 years of life expectancy if the present air pollution ranges persist. However, if the decline in particulate ranges continues on the similar charge within the coming years, life expectancy within the northern plains might enhance by 1.2 years, it mentioned.
“The report clearly reveals that even a modest discount in air air pollution ranges might result in elevated life expectancy. Air air pollution, even at low ranges, considerably shortens lives and poses severe public well being dangers.

“Our present nationwide air high quality requirements fall in need of defending public well being and have to be revised in keeping with World Well being Organisation tips. We’ve the instruments and applied sciences to unravel the air air pollution disaster, what we’d like now could be the political will to implement them,” mentioned Avinash Chanchal, Marketing campaign Supervisor, Greenpeace India.
The report mentioned that PM2.5 concentrations declined by 19% on common in districts with cities lined by India’s flagship programme on air high quality administration, the Nationwide Clear Air Programme (NCAP), whereas districts not lined by the programme noticed a 16% decline.
Nevertheless, barring Dhanbad, not one of the districts with the very best decline in PM2.5 concentrations are lined by the NCAP framework.
Launched in 2019, the NCAP is India’s first nationwide effort to set clear air targets, aiming for a 20-30% discount in particulate air pollution by 2024, utilizing 2017 as the bottom yr. The revised goal is a 40% discount by 2026, with 2019-20 as the bottom yr.
The programme covers 131 non-attainment cities, which persistently failed to satisfy the prescribed nationwide ambient air high quality requirements between 2011 and 2015.
“As of 2022, air pollution in districts with non-attainment cities has declined by 18.8% relative to 2017, including 10.8 months to the life expectancy of 446.7 million residents of those districts and 4 months to India’s nationwide common life expectancy,” the report mentioned.
If India meets the NCAP goal, residents in non-attainment areas might see their life expectancy enhance by two years in comparison with 2017. India’s nationwide common life expectancy would additionally enhance by an extra 7.8 months in consequence, it mentioned.
The EPIC group emphasised that in India, the place the annual PM2.5 customary is 40 micrograms per cubic metre, greater than 40% of the inhabitants breathes air that exceeds this customary.
Nevertheless, India is responding by implementing modern insurance policies. In 2019, Gujarat launched the world’s first marketplace for particulate air pollution, which has since decreased air pollution by 20-30% in Surat and is quickly increasing to different cities and states.
These kind of modern insurance policies show that it’s doable to attain enhancements in air high quality and folks’s well being, with out unduly impeding financial progress, the researchers mentioned.
The report additionally praised India’s clear cooking programme, the Pradhan Mantri Ujjwala Yojana, saying that the decline in emissions from the residential sector in India can largely be attributed to the nationwide rollout of this scheme.
It attributed the discount in transport-related emissions to the decreased use of diesel within the transport sector.
