The new measure is part of an 875 million pound effort by the mayor's office to address air pollution in London, with the introduction of an Ultra-Low Emission Zone (ULEZ) slated for 2019.
Broadly speaking, that means if your auto was built prior to 2006 and you drive into certain parts of London between 7am and 6pm during the week, you'll have to pay the £10 T-Charge as well as the £11.50 Congestion Charge.
RHA chief executive Richard Burnett said: "We fully appreciate Mayor Khan's vision for a cleaner, healthier London".
The £10 emissions surcharge is expected to affect around 10,000 of the oldest, most polluting vehicles - those that do not meet "Euro 4" standards, one of the EU-wide categories that define acceptable levels of harmful exhaust emissions.
"This is the time to stand up and join the battle to clear the toxic air we are forced to breathe". He explained that the introducing the T-Charge over an extended area of the capital "will be a much bigger issue for many more London road users than if it had just been in a central area".
"As mayor I am determined to take urgent action to help clean up London's lethal air", commented mayor of London, Sadiq Khan.
It is applicable to Pre-Euro 4 vehicles in the zone, which covers all of central London to the south of King's Cross station, to the east of Hyde Park, west of the Tower of London and north of Elephant and Castle.
A report last week found that pollution is killing 50,000 people in the United Kingdom each year, with the chief executive of the British Lung Foundation saying air pollution is reaching "crisis point worldwide".
Bailey says that small businesses with older vehicles will be hardest hit, facing fees of £2,600 a year or having to fork out between £3,000 and £7,000 to renew their vehicles.
"By boasting about a policy that so disproportionately penalises London's poorest drivers and puts jobs at risk, the Mayor is simply blowing more smoke into the capital's already-polluted atmosphere".
"The Ultra-Low Emissions Zone, plus this means that by 2020 - the end of my first term - [there will be a] 50% reduction in nox and particulate matters in Central London", he said. Will it be rolled out across other United Kingdom cities in the near future?
