<p>Information on road traffic deaths in London boroughs is not collected by the Department
for Transport in the form requested, because the Department does not hold information
on which London boroughs have implemented 20mph limits, nor when the limits were installed.</p><p>
</p><p>The Government has not conducted any specific research into levels of pollution
produced by a new 20mph limit in the relevant London boroughs. The air quality plan
for tackling roadside nitrogen dioxide concentrations in the Greater London Urban
Area published in July 2017 provides details of measured nitrogen dioxide concentrations
in London between 2001 and 2015.</p>
