ULEZ reduces 13,500 cars daily & cuts toxic air pollution by a third

Since introducing the ULEZ new data reveals that:
• Roadside nitrogen dioxide (NO2) pollution has reduced by 36 per cent in the zone. This is measured from February 2017 to September 2019, to reflect when the Mayor publicly confirmed the Toxicity Charge (T-Charge) – the predecessor to the ULEZ - and people started to prepare for the schemes. Analysis in today’s City Hall report estimates that the reduction in NO2 pollution solely attributable to the ULEZ is 29 per cent*.
• None of the air quality monitoring sites located on ULEZ boundary roads have measured an increase in NO2 pollution levels since the scheme was introduced in April 2019.
• From March to September 2019 there was a large reduction in the number of older, more polluting, non-compliant vehicles detected in the zone: some 13,500 fewer on an average day, a reduction of 38 per cent.
• 77 per cent of vehicles now in the zone now meet the ULEZ emissions standards. This is much higher than the 39 per cent seen in February 2017 and the 61 per cent in March 2019 .
• NOx emissions from road transport in the central zone are now 31 per cent (200 tonnes) lower than if the scheme was not in place. This is ahead of schedule to meet the 45 per cent NOx emission reduction expected in the first year.
• There was a reduction in traffic flows in central London in May and September 2019 of between three and nine per cent when compared to 2018, indictaing the wider benefits of the ULEZ in encouraging people to switch to walking, cycling or using public transport**
• The ULEZ is also tackling the climate emergency. After six months, carbon dioxide emissions from road transport in the central zone are four per cent (9,800 tonnes) lower than if there was no scheme. When compared to 2016 levels, this equates to an expected 13 per cent reduction in carbon dioxide emissions if the current compliance rates continued over the course of this year.
