AIR QUALITY MATTERS


Royal Borough of Kensington and Chelsea

The following chart presents data measured contiuously at four reference sites in RBKC and at Shepherd's Bush, doing so as annual averages for the average of each consecutive month.   Of these, "North Kensington" is classified as an "urban background" site, where there is little traffic and industry.


 Source of data: North Kensington, the other four prior to 2017 and from 2017
 

The following chart shows how the annual average concentration of NO2 changed between 2010 and 2016 at prominent sites in the Royal Borough of Kensington and Chelsea (- the data derive from monthly measurements by diffusion tubes):


Source:  based on Table D “Air Quality Annual Status Report 2016”  Royal Borough of Kensington and Chelsea (July 2017, but not yet published on the Council's website) and a London Wide Environment Programme report

The data above indicate that NO2 concentrations greatly exceed the legal limit at all the sites shown, and likely to remain so for several more years.  The legal limit (40 micrograms per cubic metre) should have been achieved by 2010.

Court rulings subsequent to cases brought by ClientEarth oblige government to ensure NO2 concentrations decline to beneath the legal limit in the shortest possible time.

Research by Imperial College [see / listen from minute  15:10] indicates that NO2 concentrations are unlikely to meet that requirement, particularly along those busy streets (and in their neighbourhood), even when the proposed Ultra Low Emission Zone is fully implemented across London.
