London Mayor Boris Johnson says he would consider adding to the capital's controversial Low Emission Zone (LEZ), despite announcing in February that the third phase of the scheme, which would extend to vans up to 3.5 tonnes from next year, was suspended.
In his new transport strategy, the Mayor says that, if required to meet emissions targets, he would consider "using further emissions-control schemes to include charges or restrictions on movements for vehicles that do not meet minimum emission standards". These may be locally targeted: in areas around schools, for instance.
However, a spokesman for the Mayor's office says they are still working with the government to explore how vehicle scrappage and subsidies for electric vehicles could reduce emissions in London.
The FTA argues that the LEZ's benefits have been "completely overesti-mated" and only catch a few older trucks. It says the scheme's £50m set-up costs and £10m annual costs could have been 
spent more intelligently on reducing emissions.
