• Ulez: what is it, how much does it cost and why is it so controversial?

The number of the most polluting vehicles driven in London has fallen by almost half since the capital’s ultra-low emission zone (Ulez) was expanded, taking almost 80,000 older cars off the roads.

About 77,000, or 45%, fewer non-compliant cars and vans were detected on average a day in September, the first month of operation of the expanded zone – compared with June 2023.
