Antonia Jennings, CEO at Centre for London, comments on the successes of ULEZ on the one-year anniversary of its expansion:

“One whole year has passed since the expansion of ULEZ – bringing with it impressive milestones in the reduction of air pollution.

Most notably, levels of NO2 have dropped by 52% in central London and 21% in outer London over the past year. This has real world benefits. Children can play more safely outdoors. Those with respiratory can feel safer living in the capital without fears of their health deteriorating. All Londoners can breathe cleaner and fresher air.

But does this policy go far enough? Our polling with Savanta has revealed that Londoners are supportive of a system in which people pay in proportion to the distance that they drive – otherwise known as a ‘pay-per-mile’ charge. 41% of Londoners polled were in favour of a ‘pay-per-mile’ charge, in contrast to 27% who were opposed.

With the successes of ULEZ plain to see, it’s time we take bolder action. Pay-per-mile is a more progressive form of taxation. The money gained could be directly invested into sustainable transport. It’s a model which would further tackle the causes of air pollution in the capital, to create a cleaner and healthier city for all Londoners.”
