The London Assemblyâ€™s health and environment committee has called for qualifying standards for congestion charge discounts to be tougher than currently proposed by Transport for London (TFL)
Cars and vans should only get a discount on Londonâ€™s congestion charge if they meet tougher emission standards than currently proposed, according to the London Assembly.
Transport for London (TfL) is currently consulting on changes to congestion charge discounts, but the London Assemblyâ€™s health and environment committee believes qualifying standards for the discount should be stricter than put forward in TfLâ€™s proposals.
In a letter, agreed by the Assemblyâ€™s health and environment committee this week (February 5), members welcomed TfLâ€™s proposal to replace the Greener Vehicle Discount with a new discount based on updated criteria.
However, the committee also suggested that cars and vans should have to meet the EUâ€™s Euro 6 standards for vehicle pollutant emissions to qualify, rather than the proposed Euro 5 standards.
The letter, signed by committee chair and Labour member Murad Qureshi, states that the application of the Euro 5 standard for air quality â€œdoes not seem likely to add much valueâ€.
The committee also agrees in the letter that, having taken evidence on London air pollution and traffic emissions, the Euro 5 standard â€œis failing to get emissions down, particularly from diesel enginesâ€.
According to the letter, the Euro 5 standards allow nitrogen dioxide emissions from diesel cars of 180mg/km, which is more than the 150mg/km required of petrol cars in the Euro 3 standard that was superseded eight years ago.Â It allows diesel vans to emit 280mg/km of nitrogen dioxide.
The Euro 6 standards, which come into force in 2014, will limit nitrogen dioxide emissions from diesel cars to 80mg/km.
As a result, the letter to TfL states: â€œThe Euro 6 standard is expected to reduce these emissions more effectively, and some petrol and diesel vehicles currently on the market meet its requirements. Therefore the Committee supports the principle put forward in your current consultation document that car models qualifying for the congestion charge discount should have the lowest emissions on the market â€“ this would be better represented by a Euro 6 qualifying standard than by the proposed Euro 5.â€
The letter was drafted in response to Transport for Londonâ€™s consultation on its congestion charge proposals, which ends today (February 8).
TfL is proposing that the criteria for vehicles qualifying for congestion charge discounts should be tightened, which could see many owners of diesel and hybrid cars that are currently exempt having to pay the full charge (see airqualitynews.com story).
The proposals have prompted criticism from motoring groups that some drivers will have to pay more to travel in London, while air quality campaigners have also voiced concerns that the stricter criteria does not go far enough to significantly improve air quality in the capital.

The committeeâ€™s response was supported by the majority of the nine-member committee, with the exception of the two Conservative Party members. The response is available on the London Assembly website.
