Pollution as Growth Killer

It’s Diwali, it’s winter, and air pollution is back in the mainstream debate as Delhi’s air turns toxic again. Delhi almost always gets the attention, but the air in the rest of the country is hardly pure and pristine. There are Delhis all over India. They just don’t get noticed, partly because nobody is measuring. According to the Centre for Science and Environment’s 2026 State of India’s Environment report, more than 64% of India’s 742 districts have no continuous air-quality monitoring at all. This in the most populous country on the planet, and the seventh largest by area. And if there’s no data, there’s no problem: you can wave away anything by calling it a vibe.

The underappreciated fact, as Alex Tabarrok points out on Marginal Revolution, quoting his interview in an Outlook Business issue on the subject, is that air pollution is a tax on India’s productivity and its economy. Or, as he puts it:

Bad air is a tax on talent.

We keep harping on about India’s demographic dividend. But if today’s young people keep growing up in cities, towns and, increasingly, villages with horrendous air, we are sacrificing part of that future. Their health worsens, they fall sick more often, and they lose more productive working days. For a country that is still developing, the hit is enormous. In the same Outlook Business issue, Anumita Roychowdhury of the Centre for Science and Environment cites estimates of what air pollution costs India each year: about 3% of GDP according to the consultancy Dalberg, about 6% according to the World Bank, and roughly 9.5% according to a study in The Lancet. Even if these numbers are only directionally right, they’re scary. B.
