The plates are being brought in especially for electric vehicles and have an eye-catching green flash on the left-hand side to highlight the fact that EVs are emission-free.
As 70-plate models are introduced at Nissan dealers, trial green number plates have been fitted to show electric vehicle customers how they could look when they hit the road later this year.
The initiative was announced by UK Transport Secretary Grant Shapps in June as part of a wider plan to drive a "green economic recovery" after the turmoil caused by the coronavirus pandemic.
The green number plates will make it easier for cars to be identified as zero-emission vehicles, helping local authorities design and implement new policies to encourage people to own and drive them.
For example, drivers could benefit from local initiatives such as cheaper parking and free entry into zero-emission zones.
Shapps had said the plates could also "increase awareness of cleaner vehicles on our roads and show people that a greener transport future is within our grasp".
Nissan has been involve with EV research and development for many years now – the emission-free LEAF hatchback was launched a decade ago and the new Ariya is just around the corner. LEAF is capable of travelling up to 370km on a single charge.
"Anything that encourages electric vehicle use is to be encouraged and we think the green plates will prove incredibly useful in terms of raising awareness of the benefits of emission-free motoring," said a Nissan spokesman.
An exact date for the introduction of the green number plates has yet to be announced.
