London takes 5 days to breach 2017 air pollution limit

LONDON — It was a powerful image: soaring high in the sky next to Big Ben was a Mary Poppins figure wearing a 
protective mask.

And for good reason: London exceeded its annual air pollution limits for the whole of 2017 on Thursday night — a 
whopping five days into the new year.

London is a world leader in nitrogen dioxide (NO2) -- levels are far higher than they are in the U.S. -- because of 
its reliance on diesel-powered vehicles. Many of the city’s iconic black cabs and double-decker buses are run on 
diesel, a major source of NO2.

Activists were expecting London to breach its limits early in the year — in 2016, it took eight days — and the 
Greenpeace environmental organization responded by staging a protest with a giant mask-wearing Mary Poppins balloon.

According to European Union and British law, no single area is allowed to exceed the hourly limits — of 200 
micrograms of NO2 per cubic meter of air — more than 18 times in a year. On Thursday night, an air-quality monitoring 
station on Brixton Road in south London breached the limit 19 times, reaching 347.7 ug/m3 at 9 p.m.

Clean Air in London, an advocacy group, said that Brixton Road reported 20 exceedances over a 24-hour period, which 
“could be a new world record for an official monitor.”

Its director, Simon Birkett, said that “with diesel vehicles responsible for 90-95 percent of NO2 from vehicle 
exhaust,” the only way to comply with the law was to “ban diesel from the most polluted places.”

He also urged pedestrians to avoid Brixton Road and urged locals to abandon outdoor dining.

“Emergency measures and action are needed,” he said.

Britain, along with other countries in Europe, bet heavily on diesel cars before they understood that they emitted 
harmful pollutants. As my colleague Griff Witte reported:
