India’s killer smog is piling on the costs to citizens, the economy

Noxious smog smothering the plains of north India is not only choking the lungs of residents and killing millions, but also slowing the country’s economic growth.

India’s capital New Delhi frequently ranks among the world’s most polluted cities.

Each winter, vehicle and factory emissions couple with farm fires from surrounding states to blanket the city in a dystopian haze.

Acrid smog this month contains more than 50 times the World Health Organization recommended limit of fine particulate matter – dangerous cancer-causing microparticles known as PM2.5 pollutants, that enter the bloodstream through the lungs.

Experts say India’s worsening air pollution is having a ruinous impact on its economy – with one study estimating losses to the tune of US$95 billion annually, or roughly 3 per cent of the country’s GDP.

The true extent of the economic price India is paying could be even greater.

“The externality costs are huge and you can’t assign a value to it,” said Vibhuti Garg, of the Institute for Energy Economics and Financial Analysis.
