London is the first city in the world to implement 24/7 Ultra Low Emission Zone. The vehicles will face emission standards inside or face a charge. ULEZ aims to reduce toxic air pollution, protect public health & a centrepiece from cleaning up London's air. Drivers can check whether their vehicle meets ULEZ emission standards using an online tool given by travel authority. Polluting vehicles will not be allowed to enter ULEZ.
