Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what recent assessment he has made of the effect of diesel engines on air quality in (a) Wallasey constituency, (b) Wirral and (c) Merseyside.

The national pollution climate mapping modelling includes assessment of air quality within Wallasey, Wirral and Merseyside. Our latest modelling for the 2017 national plan showed no air pollutant exceedances in Wallasey and Wirral.

There were modelled exceedances of nitrogen dioxide in Liverpool City Council in Merseyside. Of these exceedances, 66% of the modelled concentrations were attributable to emissions from diesel engines for the Liverpool Urban Area reporting zone.
