New figures suggest pollution levels of gases linked to traffic rose by about 10% in the centre of Glasgow after the introduction of a ULEZ scheme a year ago.

The Telegraph reports Nitrogen dioxide levels in the city’s Hope Street, which has repeatedly had the country’s worst air quality, were measured at an average of 34 micrograms per cubic metre between June and August this year.

This compared with a figure of 31mg in the same period last year, before the city’s low emission zone (Lez) was introduced – a rise of 9.7 per cent. The legal limit is 40mg.
