Phase three of London’s Low Emission Zone (LEZ) has been suspended just a year after the controversial emission-reducing scheme was introduced.

Phase three of the scheme - which sought to bring smaller commercial vehicles under LEZ regulation - will now face public consultation and is expected to be scrapped due to significant concerns over its cost to industry and small businesses in particular.

Gordon Telling, the Freight Transport Association’s head of Policy for London, said: “City Hall has listened to industry and the FTA and reviewed this unpopular and ill-conceived scheme, which amounted to little more than window dressing.

“The LEZ accomplished very little, mainly because a large number of emission-compliant road vehicles already operate in and around London. Unfortunately the cost to business - and to Londoners - has been far from small.”

The LEZ was introduced on 4 February last year to reduce emissions in the capital, but it has left local residents and businesses with a massive bill to pay and very little improvement in air quality, according to the FTA.

“LEZ’s benefits were completely overestimated, unlike the price tag that went with it. Taxpayers’ money has been wasted on publicity, signage and cameras to catch just a handful of older, more polluting trucks. The cost of finding this out has been about £50 million in set up costs and a further £10 million in annual running costs.

“At least now the damage has been limited and we can start to look at more intelligent ways of reducing emissions in the capital without more companies being put out of business.”

Bringing vehicles up to the required standards has already cost businesses around £40 million it was feared that if the green light had been given to widen the scheme to include small vans many thousands of small businesses, including greengrocers, would have to face significant costs.

The FTA contends that the Freight Operator Recognition Scheme (FORS) - a unique, industry-led membership scheme that aims to transform freight delivery in London - will be a far more effective way of reducing emissions in London than LEZ as it prioritises best practice procedures including reducing freight’s impact on the environment.

By contrast, the FTA claim LEZ has effectively diverted potential funds away from buying cleaner vehicles that could have been achieved via incentivising commercial vehicle operators to adopt electric, hybrid and cleaner vehicles.

“Perhaps now the ‘carrot’ and not the ‘stick’ approach will be adopted to avoid hitting smaller businesses while encouraging the larger companies who operate larger fleets to invest in cleaner vehicles,” said Telling.
