India’s capital New Delhi opened its first “smog tower” on Monday aimed at reducing the air pollution blamed for thousands of premature deaths every year, but experts were sceptical.<\/p>\n


\n <\/section>\n

Concentrations of tiny deadly particles in Delhi’s air regularly exceed safe limits by up to 20 times, particularly in winter when its 20 million people are enveloped in a noxious grey blanket of smog.<\/p>\n

Forty giant fans on the 25-metre (82-foot) tower will pump 1,000 cubic metres of air per second through filters that halve the amount of harmful particulates in a radius of one square kilometre (0.4 square miles), according to engineers.<\/p>\n

“Today is a big day for Delhi in its fight for clean air against pollution,” Chief Minister Arvind Kejriwal said after the inauguration near the busy shopping area of Connaught Place.<\/p>\n

The installation “is being looked at in an experimental way. We will analyse the data and if it’s effective, more towers will be built across Delhi,” Kejriwal added.<\/p>\n

The tower cost $2 million and critics say erecting a sufficient number to clean the air substantially across the city would cost huge amounts of public money, and that efforts would be better directed at the sources of the smog.<\/p>\n

These include vehicle exhaust, heavy and small-scale industry, construction activity, the combustion of waste and fuel, and in winter the burning of crops in neighbouring regions.<\/p>\n

“Let’s just be clear that this is futile, an absolute waste,” Karthik Ganesan from the Council on Energy, Environment and Water told AFP.<\/p>\n

“Now that taxpayers’ money has been spent, let Delhi be the test case for all other Indian cities… to ensure no other city spends on such ideas which we can’t afford,” he added.<\/p>\n

India has 14 of the world’s 15 most polluted cities, according to the World Health Organization.<\/p>\n

A 2020 study in the Lancet<\/i> found there were 1.67 million deaths in the country attributable to air pollution in 2019 including almost 17,500 in Delhi.<\/p>\n

In 2018 China built a much larger 60-metre smog tower in the polluted city of Xian, but the experiment has not spread to other cities so far.<\/p>\n\n
