Polluted London plans restrictions on road traffic
Print Edition
GONE are the days of London’s “pea souper” smogs, but like many European cities, the British capital is again being choked by pollution — and has road traffic firmly in its sights.
In 1952, the Great Smog suffocated London for five days, bringing the city to a standstill as soot-filled clouds descended onto the streets and into people’s lungs, leaving over 12,000 dead.
The crisis prompted a clampdown on the use of coal in the city, but decades on, pollution is still causing over 9,000 premature deaths per year.
This time, the key culprit is nitrogen dioxide (NO2), produced by cars and trucks — and particularly diesel engines, which emit three times more NO2 than petrol vehicles.
“Industry ... is part of the problem, but the focus, the problem areas are next to roads,” Gary Fuller, a senior lecturer in air quality measurement at King’s College London, said.
London Mayor Sadiq Khan is on a personal mission to deal with the “lethal” air in the city, after blaming pollution for his adult-onset asthma.
This week he announced plans for new charges for diesel cars and older petrol vehicles, which could see drivers pay 24 pounds (US$30) a day to enter central London by 2019.
But the issue is not just confined to the city center, or indeed to the capital itself.
“The NO2 limit value is exceeded in many major cities up and down the country,” Fuller said.
More than 40,000 British deaths a year are attributable to exposure to outdoor air pollution, according to a survey last year by the Royal College of Physicians and the Royal College of Pediatrics and Child Health.
It warned that air pollution plays a role in many of the major health challenges of our day, linked to everything from asthma to cancer, obesity and even dementia.
It can have a particularly damaging effect on children, said a new study by environmental NGO Greenpeace.
