I propose to take Questions Nos. 305 to 307, inclusive, together.

Policy responsibility for air quality, which would include emissions from cars, is a matter for the Department of Communications, Climate Action and Environment.

I have not commissioned any study or research into the number of persons negatively impacted by NOx emissions from diesel vehicles nor does my Department hold information regarding the cost to the public health system of health-related cases linked to NOx emissions.
