Three years on from its expansion, one thing is clear: ULEZ works.
The evidence from central London shows the real, measurable impact of cleaner air - fewer toxic pollutants, healthier lungs, and better outcomes for children growing up in our city.
Expanding ULEZ was a tough decision made in the face of loud opposition, but it was the right one for millions of Londoners’ health. Toxic air worsens asthma, increases the risk of heart disease and strokes, and shortens lives.
Leadership today means making difficult decisions, and having the courage to see them through.
