Artificial Light and Noise: Effects on Human Health (Science and Technology Committee Report)

Lord Randall of Uxbridge Excerpts

Thursday 9th May 2024 Grand Committee

[Lord Randall of Uxbridge (Con)]

My Lords, I should start by declaring my interest in the register as a council member of the RSPB because I will, as noble Lords would expect, concentrate on the biodiversity angle of this issue. I say to the noble Baroness that I am a member of Buglife; I have had some excellent briefing from David Smith and Matt Shardlow.

I congratulate the committee, in particular the chair, on an excellent report. I have already heard a great deal. If there is one thing about following noble Lords, it is that, if I am not sounding reasonable, I am finding myself intellectually unequal. It is a great thing to listen to noble Lords; I rather wish I had not put my name down sometimes.

The noble Earl, Lord Russell, and the chair made a point about constituency MPs. With regard to noise in its many forms from road traffic, a new road surface was eventually put down on the A40 where it was dualled because it was causing so many problems; that was probably around when I first came into Parliament, in 1997 or 1998. The neighbour problem is huge. It is not that the neighbours are necessarily noisy; it is just that the walls are so thin. Ultimately, the two other big issues that used to be in my constituency have not gone away. One was Heathrow and the impact of noise on residents, particularly children; there was a report on cognitive problems. The other was HS2, although it put quite a lot of effort into trying to show that it was not going to be noisier than what was already there with ordinary trains. Anyway, I digress.

I want to talk about light pollution. We know that it occurs and that we have to be considerate about safety problems and things like that. Research published in 2023 revealed a rapid increase in global light pollution levels of 10% a year for the past decade, which represents a doubling of sky brightness every eight years. We occasionally see maps on TV of the light coming from Europe. It is quite scary because what is that doing to humans and to our natural world? No artificial light is truly environmentally friendly due to its disruption of the natural rhythm of day and night. I say to the noble Baroness, Lady Neuberger, that, having spent a good deal of the past year in hospital—and with another little rest period coming up—I understand her position on light. I know why it is there; I think they just switch it on to annoy me from time to time, but that is life.

These are all very serious matters. We know about the problem of insects declining. There is a great deal of evidence to show that that is due to lots of things but one of them is artificial light, such as street lights. We also have a problem, which has already been mentioned, with marine animals. I do not know whether your Lordships remember seeing “Planet Earth II”; I am talking about the last episode, I think. When young turtles hatch, they normally go towards the moon, but they were fooled by a taverna and were all crunched into the road because they thought the moon was the other way. That is a good example of the sort of problem we face.

I am not entirely convinced in some areas. In the countryside, there are a few areas where it is still quite dark at night. I am not sure that it is that dangerous. I understand the problem of personal safety, of course, but I am not entirely sure that people do not feel better just looking up at the stars—assuming it is not cloudy.

One reason why I shall be utterly reasonable is that my noble friend Lord Benyon is the most reasonable of men. I do not think that Defra is not doing its full amount; I think that it is down to some of the other departments, so I echo the call for something that encompasses all the departments. I make just a little plea on that—in an entirely reasonable way, I assure my noble friend.

Funnily enough, as I was coming here today, the Metropolitan line let me down—or a fire at Rayners Lane did—so I got an Uber with a gentleman to Harrow-on-the-Hill. It turned out that he is in the lighting industry. We were discussing this, and he said that there are lots of controls for lighting to make sure that it is not invasive in many areas. He also mentioned that there are switches, so in those large buildings that we see lit up somebody can actually go round and switch the lights off. That would save companies money and save us on some of the emissions. The other thing he said was that he had just been putting in some bat-friendly lights around Kew Gardens. These things exist; we just have to make sure that they are not just for those places that consider them but go a little wider.

I was interested to read that in France’s national biodiversity strategy and action plan, in response to COP 15, there is an ambition to achieve a 50% reduction in light pollution by 2030. Slovenia, Czechia and Croatia are adopting regional laws around that too. Perhaps we can learn something from that.

I tried making amendments along these lines to the Environment Bill and got quite a lot of support, but possibly I was too reasonable in listening to the answers. I will not let this go away, because it is incredibly important. Addressing light pollution will have multiple benefits in tackling nature, climate, energy and economic crises. I will leave it there and wait to hear from my noble friend.
