London has plans in place for an ultra low emissions zone, which will also hit cars seen as the most polluting - and older vehicles - in the area currently within the Congestion Charge zone.
The ULEZ will operate 24 hours per day, seven days a week, and come into force in September 2020. Plans have also been consulted on to extend this out to the wider London area too, potentially limiting cars within the bounds of the North and South Circular.
Paris followed suit with mandatory stickers and potential fines from Monday, with mayor Anne Hidalgo determined to reduce pollution in the capital by restricting access for old cars and lorries.
A total of 22 other French towns are also mulling over introducing the emissions certification system by 2020, which would ultimately make applying for a sticker almost a necessity if you're planning to drive to France from the UK for holidays.
Admired the world over for its impeccable taste and effortless style, France celebrates beauty, sophistication and style.
