My Lords, I intervene for a moment in support of Amendment 191, to which I have added my name, and to say a couple of things, partly by way of reiteration of what the noble Lord, Lord Ravensdale, said in what I thought was a very capable exposition of the reasoning and purpose behind the amendment.
First, of course we already have in legislation, and have had for some time, a duty in plan making to contribute to the mitigation of and adaptation to climate change, but I am afraid it is not doing enough.
That much is evident, and what the noble Lord said, which is absolutely right, is that some local planning authorities who want to do the most to change their approach to plan making and spatial development in order to mitigate and adapt to climate change are finding that the structure of planning law makes that more difficult.
In resisting the amendment, my noble friends may say that it would lead to litigation. Well, first, it all leads to litigation. Secondly, the problem at the moment is that, for a local planning authority, going down the path of doing the really necessary things to mitigate climate change involves transgressing other objectives under planning law. For example, we can have a big debate about the green belt, but sometimes—as Cambridge’s examination before its local plan process demonstrated—if you really want to make a difference, the structure of development must focus on urban extensions and along public transport corridors—and if you try to do that around London, you hit the green belt. So you have to balance these things.
If we are serious about adaptation to or mitigation of climate change, we must raise it in the hierarchy of considerations—which is exactly what the amendment from the noble Lord, Lord Ravensdale, sets out to do. It is not an objection to the amendment that we create a hierarchy that could give rise to challenges; it is its purpose and objective and that is why we should do it.
I will reiterate a second point he made so that noble Lords understand the value of the amendment. It takes a principle presently applied to plan-making and applies it both to the Secretary of State’s policy-making functions, including national development management policies, and to determinations of planning permissions. It puts it right in the midst of the whole structure, from the Secretary of State making policies to local authorities making plans and looking at planning applications and determining them. That is the only way competently to address the range and scale of issues that climate change presents to us. It takes it from policy through to individual decisions, and that is why I think it deserves our support.
