The Mayor of London and TfL are helping to clean up London's air through the Ultra Low Emission Zone.
Toxic air pollution is the biggest environmental risk to Londoners' health, and traffic emissions are the biggest source of toxic air in London.
Toxic air pollution increases your risk of heart and lung disease, worsens chronic illnesses such as asthma, and puts children's health at risk. It's not just a central London problem. Many areas across the city are exceeding the legal limits for pollution.
The aim of the expanded ULEZ is to help reduce harmful nitrogen dioxide by around 30% across London.
Many of those who travel in the expanded ULEZ have already taken action to clean up their vehicles and help clean up London's air. More than 80% of vehicles are now compliant, which is up from 39% in February 2017 when plans for the larger area were first announced.
We don't make a profit and we are committed to reducing our costs. Any money received from the ULEZ will be reinvested into improving the transport network, including cycleways, buses and Tube, and helping to improve London's air quality.
Use our vehicle checker to find out if your vehicle meets the emissions standard and the charges you need to pay.
To help clean up London's air, we are encouraging all Londoners to walk, cycle or use public transport.
People who walk or cycle 20 minutes a day as part of their regular journeys feel improved mental and physical wellbeing. Look out for the temporary cycle lanes and wider pavements so you can walk or cycle more safely.
To encourage cycling, we:
Travel off-peak anywhere between Zones 2 and 6 for £1.60, and use our Hopper fare to take unlimited bus or tram journeys within one hour for £1.65. This includes our night buses.
Download the TfL Go app on the Apple Store or Google Play for live travel updates and to find quiet times to travel. We regularly clean our services using hospital grade antiviral disinfectant.
Every bus you catch meets the highest emissions standards.
We've also been working to create cleaner taxis and cleaner private hire vehicles.
Car Clubs are short-term car rental services. They give members access to locally parked cars, through paying by the minute, hour or day.
Many car clubs now operate electric or hybrid vehicles, which can help reduce emissions and improve air quality. Find out more about car clubs and the companies that provide them.
