Lords ChamberMy Lords, I am delighted to support the idea that we should go for 20 miles per hour speed limits. The consequences of accidents at 20 miles per hour are much reduced. It makes for a much friendlier environment for walking and cycling and, as the noble Baroness said, it absolutely results in improvements in air quality. We do not need the centres of our towns and cities to be places of rush and danger, particularly with the decline in the viability of our high streets. We want them to be places where people feel comfortable, enjoy being and want to go to for all sorts of reasons. It ought to be easy and conventional. It ought to be the rule that, where people are numerous and we want them to be at ease, we go for a 20 miles per hour speed limit. It is absolutely justified in terms of the objectives of this Bill.
So far as air quality generally is concerned, I come back to the point, which I made in earlier debates, that we must have better research. We are quite capable of it. It is not very helpful to talk about PM2.5 as if this is some universal characteristic; it is just a size. It does not tell you anything about where the particles came from and what, therefore, can be done to reduce their concentration. As the noble Lord, Lord Tope, pointed out, in some places lockdown resulted in sharp drops in nitrogen oxides and other such pollutants but no drop in PM2.5, so what is going on here? Were the particulates really coming from diesel engines, or have we, again, been barking up the wrong tree? It is not difficult to find the answer. All you have to do is pick out individual particles, analyse them and find out what their origins are. A particle that comes from burning wood is very different from a particle that comes from diesel—at least on average. A particle from emissions from a heavy industrial source is very different from one from a light engine. We need to do this research, and we need to do it locally, so that we can undertake actions that make a difference.
The main difficulty that I have with the amendments tabled by the noble Lord, Lord Tope, is that they seem to assume the sources of pollution are all local. How do we know unless we have done the research? If we do the research, that immediately gives us the moral and intellectual authority to take action against a particular source of pollution. If we just generalise about these things, we will end up hitting lots of imaginary enemies as well—perhaps—as a real one. It is really important that we get the level of research well up. We should make it local and consistent so that we really understand what is going on when it comes to air pollution.
I understand that the noble Lord, Lord Krebs, has withdrawn so I now call the noble Baroness, Lady Finlay of Llandaff.
I have received requests to speak after the Minister from the noble Lord, Lord Lucas, and the noble Baroness, Lady Bennett of Manor Castle. I call the noble Lord, Lord Lucas.
My Lords, I would be very grateful if the Minister—in writing if not immediately—could let me know what steps the Government have taken or intend to take to enable local action in this area? My particular concern, as ever, is the town of Eastbourne. We are told from time to time that our air quality is bad; we are never told why. What support can the Government offer for properly testing the air pollution we are said to have, so that we can have a proper diagnosis of where it is coming from and therefore direct our local efforts accurately at dealing with it?
Similarly, the current system for trying to get speed limits moved to 20 miles per hour is very time-consuming and difficult and imposes a lot of burdens on the higher county authority. Is there not some simpler way in which an expression of local will might convert into something happening without the need for deep, long consultations? This is a matter of policy and of the direction we want to take a community in. It really should not have to justify itself at every cobblestone.
