Ultra Low Emission Zone

Ultra Low Emission Zone, VCCP / Transport For London
London’s air is slowly killing us. Over two million Londoners live in areas that exceed legal limits for NO2, of which over 400,000 are children*. With the launch of the Ultra Low Emission Zone (ULEZ) in 2019, London met that battle head on. With the stakes so high, our campaign simply had to work. By clearly planning out three distinct objectives, we delivered a powerful new campaign that:
- Made the wider, emotive case for Londoners to rethink their impact on London’s air quality
- Encouraged compliance by informing and educating on the need for the zone
- More broadly, got the whole of London to start thinking more about how they could change their driving behaviour, switching more of their journeys from car to public transport and active travel

And we’re already driving significant change, both in priming drivers to reconsider their behaviour, and impacting actual behaviour.

93% of Londoners who recognise our campaign are aware of ULEZ. More Londoners than ever recognise that driving is one of the key contributors to air quality, and record numbers want to drive less and use public transport more.

We've delivered compliance levels significantly above target and London’s air is getting cleaner. Roadside nitrogen dioxide (NO2) pollution has reduced by 36% in the zone. After six months, carbon dioxide emissions from road transport in the central zone are 4% (9,800 tonnes) lower. With lives at stake, this progress undoubtedly benefits us all.
