Question

Do you agree that: the PM10 daily limit value has been breached in London in 2010; the NO2 hourly limit value has been breached in London in 2010; the NO2 annual mean limit value will certainly be breached in London in 2010; the NO2 annual mean limit value plus maximum margin of tolerance may be breached in London in 2010?

Answer

Answer for Air quality limit values

Answer for Air quality limit values

Answered By: 
The Mayor

The UK Government is required by the EU Air Quality Directive to report air quality data, including compliance with limit values, to the European Commission every year. The latest report was published in September. The GLA monitors and models air quality in London and the latest data were used to inform my Air Quality Strategy which I published on 14th December.

Modelling shows that measures already underway will allow all of Greater London to be compliant with EU limit values for PM10 in 2011. However, my Strategy recognises that it is extremely challenging for the NO2 limit values to be met in London by 2015. That is why my Strategy also includes measures that need to be taken at national level by the Government to achieve NO2 limit values in London by 2015.
