Mayor says his work to address air pollution in the capital is entirely transparent and refutes suggestion London has worst NO2 levels in the world
The London Mayors office has denied claims from campaigners that Boris Johnson mislead MPs during a recent evidence hearing as part of an enquiry into air quality in the UK.
The Mayor, Boris Johnson, appeared before the Environmental Audit Committee (EAC) in September (see airqualitynews.com story), during which he refuted suggestions that London has some of the worst nitrogen dioxide levels in the world.
His comments followed a Sunday Times interview with Kings College Londons Dr David Carslaw in July, in which Dr Carwlaw suggested that Oxford Street had the highest hourly and annual mean readings for nitrogen dioxide in the world and were as high as they have ever been in the long history of air pollution (see airqualitynews.com).
And, in letter correspondence published by campaigner Simon Birkett of Clean Air in London (CAL), the Mayors advisor Matthew Pencharz again privately refuted Dr Carslaws claims to Kings College Londons Environmental Research Group (ERG), stating that he was surprised and disappointed with the comments in the Sunday Times.
Mr Pencharz wrote: I believe the statement to be misleading for three reasons: pollution levels in London are lower than for many other world cities, other monitoring sites are currently recording higher concentrations of NO2 than at Oxford Street and various monitoring sites have reported much higher concentrations of NO2 in the past.
He also wrote that it was important that public statements are supported by evidence and set in proper context, adding that I look forward to work with Kings ERG and trust that in future more rigour will be applied to public statements made by members of the Groups staff.
However, CALs Mr Birkett questioned the data and methodology in a September report by consultancy AMEC commissioned by the Mayor, which found that London ranked 9th on the health impacts index, 15th on the city wide index and 17th on the traffic-focused index in a comparison of 36 world and European cities (see airqualitynews.com story).
Mr Birkett said that as a result the EAC may have been misled by Mr Johnson over his comments regarding nitrogen dioxide levels on Oxford Street, and that Kings College London scientists were unfairly criticised by Mr Pencharz.
Mr Birkett said: In CALs considered opinion the Mayor has made statements to the EAC and elsewhere the effect of which is to distract people from the original revelation i.e. to suggest media coverage was about air quality in general not the highest NO2 in particular.
However, responding to the claims, a spokesperson for the Mayor of London said: These claims are completely untrue and unfounded. The Mayors work to assess and address Londons air quality challenge is entirely transparent. He continues to take the problem extremely seriously and is working with a wide range of stakeholders to take forward a comprehensive range of measures to reduce air pollution and protect the health of Londoners.
The Mayors spokesperson said that the AMEC study was independently peer-reviewed to ensure the methodology it used was robust and fair, adding that any claims that the Mayor misled the Environmental Audit Committee are categorically false.
In related news, Mayor-championed proposals for an ultra low emission zone in the capital by 2020 are expected to go out for public consultation next week, although a spokesperson for Transport for London was unable to confirm a date.
