London mayor Sadiq Khan has announced plans to crack down on the capital's dirty air - including a daily "toxicity charge" on the most polluting cars from next year.
Speaking at Great Ormond Street Hospital on the 60th anniversary of the Clean Air Act, Khan called London's pollution problem a "health emergency", saying: "With nearly 10,000 people dying early every year in London due to exposure to air pollution, cleaning up London's toxic air is now an issue of life and death."
The toxicity charge - dubbed the "T-charge" - involves imposing an extra £10 (on top of the existing daily £11.50 congestion charge) for all vehicles entering central London with pre-Euro 4 emission standards - which basically means all cars registered before 2005.
Other proposals included introducing the central London Ultra-Low Emission Zone one year earlier in 2019 and putting forward a national diesel scrappage scheme for the government to implement.
The public have until Friday July 29 to give feedback on the proposals.
