Health Desk—Nov 28, 2017: A recent study said targets for reducing illegal levels of NO2 pollution from vehicles will be achieved more quickly than the government expects.
According to the researchers, government projections of future NO2 are too pessimistic, because they ignore the latest real world data.
They say cities may achieve roadside emissions standards several years earlier than ministers expect.
The research is published in the journal Nature Geoscience.
The authors at the University of York warn that despite the adjustment, the government is still lagging badly on NO2 targets.
And they say the air in the UK's big cities remains dangerously polluted from many different compounds.
But how did the government miscalculate NO2?
The authors say it's because they relied on projections of future emissions, rather than on real world roadside emissions data at the European Environment Agency (EEA).
Notable, the government's figures are based on tailpipe readings from vehicles with new particle filters. They projected these figures forward to estimate future pollution levels.
