My Lords, it is a pleasure to speak after the noble Lord, Lord Randall of Uxbridge. I think the last time I spoke after him was to congratulate him on his maiden speech. He brings, of course, great focus and authority to this debate. I welcome this group of amendments generally and congratulate the noble Baroness, Lady Hayman, and the other noble Lords who have tabled the amendments on bringing forward the issue of targets and particularly the PM2.5 measure.
Like the noble Lord, Lord Whitty, I accept the importance of these targets while pointing to other types of air pollutant of possibly equal toxicity and potential for harm. I am informed about this because over the years I have had many emails in my parliamentary mailbox with personal accounts from those whose health is significantly and adversely affected by air pollution, particularly by being near to major road systems.
Fundamentally, all these targets have to drive a culture change. I think of my three London-resident children who during the pandemic reported how air quality in the metropolis had improved and, sadly, how it has once again deteriorated as things return to what we might call normal. While I commend municipalities bringing in ultra-low emission zones for urban centres, I think that permitting owners of polluting vehicles to pay for the privilege gives the wrong message.
The noble Lord, Lord Whitty, referred to a range of non-vehicular polluting activities, including those from construction with which I am familiar. Not so many months ago I witnessed a group of contractors engaged with public pavement repairs using a petrol disc cutter to trim concrete slabs. This was taking place in a busy London shopping street. I will not bore noble Lords with a detailed description of the noise, uncontained dust and odours that were released into the air, but it could just have easily have been welding, sanding, atomising sprays, evaporating solvents or material handling that was releasing pollution into urban air. I also observe that far too many food premises emit odours and fumes at unacceptable levels. One I know well in a major Surrey town blasts motorists as they wait at
traffic lights with the outpourings of its extractor system. I suppose one might say that that was a form of poetic justice.
Only recently I learned that the metropolitan Clean Air Act, to which the noble Lord, Lord Randall, referred, permits the burning of firewood in homes. I thought that had been banned a long time ago. The Prime Minister’s comments about insisting on seasoned firewood are very welcome, but the wood also needs to be dry, kept dry and not be full of resins, as are some softwoods. As somebody who uses a wood burning appliance—but not in an urban area, noble Lords will be glad to hear—I question how good the understanding is of these factors concerning supplies of firewood and the knowledge of consumers. Urban atmosphere is, after all, a vital common good for health and well-being, tourism, productivity and, in turn, commerce.
The noble Lord, Lord Young of Norwood Green, is right that we cannot simply all take a hairshirt approach and that the laws of unintended consequences beset us as we try to move from one mode of transport, perhaps, to the other. He rightly referred to the role of innovation. However, to repeat my earlier comment, most of all we need collective cultural change, better information and regulation that drives such responses as we wish to see come out of this Bill.
