My Lords, I start by thanking all noble Lords who have spoken in support of 20’s Plenty. It has been much appreciated. I know it has not been discussed in this House much before, if at all; it is a new concept but I think it is a really worthy one. I am sorry that the noble Lord, Lord Whitty, did not feel able to express his support, but I hope in time to convert him to the cause.
I found the Minister’s response disappointing and complacent. Air pollution is such a devastating killer, and it is not a pleasant way to pass away—particularly in light of the compelling and chilling evidence from the noble Baroness, Lady Finlay of Llandaff, who speaks with huge knowledge in these matters. The noble Lord, Lord Lucas, had already asked about the Minister’s assertion about 30 mph limits being in place and the opportunity for local authorities to change that to 20 mph. That is exactly the situation we are trying to reverse; it is complicated and costly, et cetera, and it would be far better to have a default limit of 20 mph and for local authorities to have the power to change it to 30 mph or whatever speed limit they think appropriate.
The Minister also asserted that we are looking for less traffic, not slower traffic. The point is that all the evidence shows there is less traffic in areas with 20 mph speed limits, because people are more willing to switch to walking and cycling when traffic around them is calmer. These 20 mph limits are really popular. The national attitude survey on transport shows that substantially more than two thirds of the public are in favour of this. The Atkins report also showed the public were in favour.
I think the Minister was referring to the Atkins report when she said there was evidence that, in some areas, 20 mph limits can lead to higher casualty rates. That report has been challenged extensively, and I believe the 20’s Plenty campaign group wrote to the Government to say it was concerned about some of the report’s findings and to ask what evidence the Government could provide on the use they made of the various comparators in particular. The group has yet to have a reply from the Government; maybe this is an opportunity for it to receive that reply, which would be much appreciated.
The 20 mph limit is popular, practical, cheap and affordable, and there are numerous bodies of evidence to support the social and environmental benefits it would bring. It would be a bold step; it would help tackle climate change and public health issues at a single stroke. I hope the Government will take the amendment seriously, but, for now, I beg leave to withdraw it.
