Environment Bill

The Minister is being generous and kind in giving way again. Has she seen the experiment in the cities of Oxford and London, where air quality detectors are on every waste truck? Every week, waste trucks go to every house in every street in the country. If we put those on every waste truck—and it is cheap—we would know the hotspots and the British public would know very quickly what sort of atmosphere their children were growing up in and what air we are breathing. Will she have a serious look at that and, in the process, discuss it with Sir Stephen Holgate, who is such a magnificent expert on all that?
