London motorists driving high polluting cars have to pay an additional £10 to drive through the capital starting today, as the Mayor of London introduces his new Toxicity Charge, or T-charge.
Sadiq Khan's new charge is added to the existing £11.50 congestion charge. This means owners of affected vehicles will have to pay £21.50 to drive through central London during enforced hours.
The extra levy has been introduced to tackle the capital's growing air pollution problem, and targets pre-Euro 4 petrol and diesel vehicles manufactured before 2005 that don't meet Euro 4 emissions standards for nitrogen oxide and particulates.
Transport for London has launched a free online vehicle checker so drivers can see if the T-charge will affect them.
The T-charge is being policed by the same network of cameras that already govern London's congestion charging zone.
Cleaning up the capital
Khan's aggressive stance to cut urban emissions has seen him also propose an extension of the planned Ultra Low Emissions Zone (ULEZ) to include the North and South Circular roads - a move that would dramatically extend the zone's extremities. Under current plans, drivers entering the ULEZ will have to pay a charge depending on how clean their vehicle is from 2020, but Khan has now said he wants to bring that date forward by one year.
The capital already has a Low Emission Zone, but this does not currently apply to cars or motorbikes.
Elsewhere, a set of 'clean bus corridors' have been proposed, which would see the cleanest buses placed on the dirtiest road routes in a bid to tackle emissions. Khan has also given Transport for London (TfL) the green light to investigate whether a diesel scrappage scheme could work in the capital. The scheme, which would offer cash incentives to diesel drivers to encourage them to choose a cleaner car, has previously been shot down by MPs, who claimed it would be ineffective and expensive to manage.
When he initially announced the plans last year, Khan said he wanted to act "before an emergency, which is why we need big, bold and sometimes difficult policies if London is to meet the scale of the challenge.
"I have been elected with a clear mandate to clean up London's air. The previous mayor was too slow on this issue, the government has been hopelessly inactive and it's Londoners who are suffering as a result."
Khan cited medical research, which claims that more than 10,000 people die annually in London due to polluted air. London's air quality has come under close scrutiny in recent years, particularly in relation to NOx emissions. Parts of the capital regularly breach EU limits for NOx; Putney High Street in West London breached the EU's annual limit just one week into 2016.
