of Delhiites will be up by nearly three years if the target of the Clean Air Programme to improve by 20 to 30 per cent in the next five years is fulfilled, according to a new study.

Union Environment Minister on January 10 launched the much-awaited Clean Air Programme to improve by 20 to 30 per cent in the next five years with 2017 as the base year.

The NCAP has proposed multiple strategies to combat air in the 102 most-polluting cities in the country.

The 102 cities singled out by the NCAP have higher levels than the average, so they stand to gain more if they follow through with their reduction action plans, according to a study by Life Index report on the 'Potential Benefits of India's War Against Pollution'.

"If all of the 102 cities reduced particulate pollution by 25 per cent, their aggregate annual average PM2.5 exposure would be 14 g/m lower than 2016 levels. This would translate to an average gain in of 1.4 years," the report said.

Among the 102 cities, a 25 per cent pollution reduction would translate to a 2-3 year gain in for the residents of 13 cities in Uttar Pradesh, two in Bihar, and Delhi, the report said.

"In Delhi, reducing the annual average PM2.5 by 25 per cent, or 29 g/m, would translate to a gain in life expectancy of roughly 2.8 years for the average resident," the report added.

"The payoffs from the successful implementation of NCAP could be substantial, with people in the most polluted areas - like Delhi - living almost three years longer," said Michael Greenstone, a professor, who created the Index along with his colleagues at the Energy Policy Institute at the University of Chicago (EPIC).

"For this reason, NCAP has the potential to become a historic and watershed moment in Indian environmental policy," he added.
