Lords ChamberMy noble friend makes a good point, and this is something that Public Health England is taking up. We work very closely with the Department of Health and Public Health England. It is extremely important that we encourage research into the effect of pollutants.
My Lords, what is the Government’s policy on diesel engines? Defra has now realised that they are in fact a dangerous source of pollution, as does the Mayor of London. Japan has for many years discouraged diesel engines. What is the Government’s policy in this direction?
We are looking very closely at this. The noble Lord will know that, in the past, it was thought that diesel engines would be less polluting and that studies of diesel engines in factories indicated that that was so. However, it did not prove to be the case when the engines were used out on the road, and that has serious implications.
