Scientists Urge UK Air Pollution Inequality Inquiry

Someone is being paid for the use of air they did not make and do not clean. The haulier whose lorries idle along an arterial road, the operator whose plant vents over a council estate, and the landlord whose leafy freehold commands a premium because the fumes settle elsewhere are each drawing an income. What service, precisely, does this payment purchase for the society that provides it?

Economic claims are justified by what they contribute, and the claim to discharge waste into a common atmosphere contributes nothing at all. It is a licence to transfer a cost. The transfer is not random. The facts placed before the UK government by some 150 scientists, MPs and activists are that, across England, lower-income and minority-ethnic communities breathe the dirtier air. A cost that falls with such regularity on the same people is not an accident of geography. It is an institution, and should be judged as one.

The strongest defence of the arrangement deserves a fair hearing. Its advocates will say that the cheaper flat beside the ring road is a bargain freely struck: the tenant accepts worse air for lower rent, the comfortable household pays more for its garden and its quiet, and the market has merely priced what each prefers. On this view there is no injustice, only a schedule of trade-offs.

The defence fails on its own terms. Of the three parties to the bargain, the tenant pays twice, once in rent and again in the lungs. The emitter, who produced the harm, is absent from the transaction and pays nothing. The owner of the cleaner street receives a premium for an amenity he neither created nor maintains, since the clean air is simply the dirt that went somewhere else. That premium is rent in the oldest sense, a return on position rather than on service. Cleanliness of air has become a form of property, capitalised into the price of land, and like most such property it is inherited by those who already hold the land.

This is why the inquiry is worth having, and also why it will not be enough on its own. An inquiry can map who breathes what. The more searching question is who is paid, and the Institute for Fiscal Studies, among the parties named, is in the business of that kind of accounting. If the ledger is drawn up honestly, it will show income flowing toward those who perform no function, and the cost of it carried by the people least able to bear it.

Picture a ground-floor flat facing the road on a July afternoon. A mother shuts the window against the traffic while her child sleeps. That closed window is a payment, made in heat and stale air, to people who will never know her name.
