London's Congestion Charge policy will be shaken up if proposals by London Mayor Boris Johnson get the go-ahead.
Johnson wants to scrap the automatic charge exemption for all hybrids, replacing it with free entry to the zone for vehicles emitting less than 100g/km of CO2 and meeting other Euro V emissions standards.
The proposal is part of a consultation released for public comment by Transport for London, which is also looking at scrapping the westward extension of the zone, effectively halving its size.
In addition, the charge will increase from £8 to £10, or £12 if you pay the day after.
However, it has also been proposed that people can spend £10 to register for the charge in order to get access to a simplified payment system.
