The symbol is being rolled out as part of the Government’s crackdown on carbon emissions.
The measures were first announced in June, with Transport Secretary Grant Shapps saying: “Green number plates will help increase awareness of cleaner vehicles on our roads, demonstrating that a more environmentally friendly transport future is within our grasp.”
He added: “A green recovery is key to helping us achieve our net zero carbon commitments while also promoting economic growth.”
Mr Shapps was the first to have the plates installed on his car – a £40,000 Model 3 Tesla with self-driving option.
If you already have a zero-emissions vehicle, you can retrofit the green number plates for about £40 from retailers such as Halfords.
The plates are optional, so you don’t need to install them on your car.
