Volvo Car UK is claiming success in its bid to review London’s current congestion charge alternative fuel exemption that it believes unfairly biases hybrid cars over other low-emitting vehicles.

In his response to the campaign, Mayor of London Boris Johnson confirmed that the exemption to the congestion charge was introduced to incentivise the take-up of more environmentally-friendly vehicles, but that vehicle technology has developed considerably since then.

Transport for London will report their recommendations by the end of the year.
