Environment Bill

Viscount Trenchard Excerpts

Report stage
Monday 6th September 2021 Lords Chamber

[Lord Carrington (CB)]

My Lords, there is very little that I can add to the speeches of the two noble Lords who have spoken already, but I will make one small point. The opportunity to prevent species’ decline and improve our environment is certainly presented by this Bill, and this amendment would assist. Addressing light pollution offers a simple solution for the species that we are trying to enhance and protect. We should bear in mind, however, that the pollution that we are trying to address does not linger when the source is dealt with—it is an easy win. It also has the added advantage of reducing carbon gases, so these two are major issues that are worth considering in relation to this amendment.

[Viscount Trenchard (Con)]

My Lords, I spoke in favour of my noble friend Lord Randall’s similar amendment in Committee. I confess to being a little disappointed that the Minister has not brought forward an amendment to deal with this. While I think that adopting too many targets that cannot be realised is not necessarily a good thing, to adopt a target for light pollution would at least show that the Government accept that it should be included together with other types of pollution. As the noble Lord, Lord Carrington, has just pointed out, it is certainly true that it can be dealt with immediately—unlike the soil—by just switching off lights or reducing the number of lights.

There is strong evidence that light pollution has a detrimental effect on birds, bats and insects. I am certainly no lover of clothes moths, and would love to find a way of introducing light pollution to my cupboards to protect my clothes, which have been devastated during lockdown. However, the Government are committed to increasing biodiversity, which means a wide range of species, including insects. Studies from Germany are among the clearest, as my noble friend Lord Randall pointed out, in showing how serious a problem light pollution is for insects, frogs, bats, birds and hedgehogs, among other species.

As for homo sapiens, we have indeed evolved to rely on the cycle of night and day to govern our physiology. We all know how exposure to light at the wrong time affects our mental functions. Light pollution is not included within the existing priority areas in the Bill. My noble friend’s amendment would provide clarity on how the Government could reduce the impact of light pollution on nature and, especially, on people’s enjoyment of it.

[Lord Hodgson of Astley Abbotts (Con)]

My Lords, I have not yet participated in the discussion of light pollution during the stages of this Bill. That is not due to idleness: it is because at the times the Committee or the House were discussing the light pollution issue, I was double-booked on the Charities Bill or the Dormant Assets Bill, in both of which I have a particular interest. That failure means that I should be very brief this afternoon, and indeed I will be. I add my support to the very important point made by my noble friend Lord Randall of Uxbridge and others, and will just make a comment about the all-pervasive nature of light pollution.

I have a house in Shropshire, on the Welsh border, well in the country, 500 feet up. If you go into my garden at night, the whole of the eastern horizon is suffused by the glow of the conurbation from Birmingham. If you swing your eyes round, you hit Kidderminster; south is Hereford; and even when you turn to the West—to Wales—there are frequent patches of light from small towns and villages. I hope, therefore, that the Minister will give due weight to the very important points made by people who are much more expert in this area than I am.
