As of 4 February, almost all of Greater London will be designated a Low Emission Zone (LEZ) as part of a scheme to improve air quality in the capital. Heavily polluting vehicles like older diesel-engine lorries, buses, coaches, vans and mini-buses are to be targeted by the scheme which will charge hefty sums for driving within the LEZ if strict emission standards are not met. Cars and motorcycles are not affected by the new rules. Operative all year round, 24 hours a day, seven days a week, the LEZ sheme should be completely phased in by January 2012.
