Environment Bill

Lord Harries of Pentregarth Excerpts

Committee stage
Monday 21st June 2021 Lords Chamber

[Lord Wigley (PC) [V]]

My Lords, I am delighted to follow the noble Lord, not down the road of the Great Stink but certainly on his references to his river experiences. I am delighted to support this amendment and thank the noble Duke, the Duke of Wellington, for tabling it. He spoke eloquently at Second Reading on the issue of the cleanliness of our rivers; I was pleased to support him then and do so now with enthusiasm.

The need to keep our rivers clean, as part of environment policy, is self-evident. Persistent reports of pollution impacting on river life, killing off fish stocks, affecting surrounding lands and environments and even causing health problems to people—particularly children, as has just been mentioned—swimming in rivers are a worrying feature of our contemporary world.

Obviously, there may be implications for landowners, particularly farmers, whose land abuts our rivers—but the overwhelming majority of such people also want to secure clean rivers. If the necessary steps are properly negotiated, they can surely be agreed. The Government should not steer shy of dealing with this issue in the mistaken belief that they will face severe opposition from countryside interests.

Equally, industrial interests must not stand in the way of cleaning up our rivers. Let us reiterate without equivocation that the polluter pays principle must be applied with such force that it becomes a real deterrent. Our water companies must equally be held to account. I want to learn from the Minister what new, effective action to reduce such pollution will emanate from this Bill and who will be responsible in practice for enforcing its provisions in this regard.

As the Minister might expect, I invite him to clarify how he and his department will co-operate with the Welsh Government in relation to rivers that run across the border. Most of them run from Wales into England, but not all and, as river pollution is no respecter of political borders, we must have an agreed approach that respects the wishes of Governments on both sides of the border but also ensures that we work coherently to reduce and, we hope, eliminate the tragic pollution of our rivers.

Incidentally, I have no problem whatever with having UK, or at least GB, standards for these purposes, provided that those targets can be achieved by constructive negotiation by the three, or possibly four, Governments with responsibility for various aspects of environmental policy in Britain.

[Lord Harries of Pentregarth (CB) [V]]

My Lords, I strongly support what the noble Duke, the Duke of Wellington, has said and many important points made by other Peers. I have only one point to make on top of the others: there has been no real improvement for so long now—certainly, not very much since 2016. In 2020, only 40% of waterways were classified as being in good health—meaning as close to their natural state as possible.

We all know that a major cause of this is sewage. In 2020, raw sewage was discharged more than 400,000 times over a period of 3 million hours, and this water, as the noble Baroness, Lady Jones, has claimed, brings huge quantities of microplastics as well. As the noble Lord, Lord Cormack, said, sewage is not the only cause: some 40% comes from run-off from agricultural industries.

The point is that, since legislation was passed and the Environment Agency has been in charge and responsible for it, there has been no real improvement. This may be due to lack of proper funding, but the fact is that it has not been able to bring about any real change. We now have the worst quality in Europe, with England comparing very badly with Scotland, where 65.7% of surface water bodies are in good health. We know this—it has been repeated time and again, and the environmental Ministers acknowledge it.

The question is: how can we ensure that real change takes place soon? Including Amendment 4 is where we must start in ensuring that good quality water is a goal that we fully intend to achieve. We must use this Bill to ensure that we achieve it.

[Baroness Bakewell of Hardington Mandeville (LD)]

My Lords, it is a pleasure to be speaking to this amendment moved by the noble Duke, the Duke of Wellington. During the past two years, many of your Lordships have raised the issue of the quality of the water in many of our iconic rivers and given very graphic examples of where pollution has been discharged, untreated, into our waterways. We have heard about chicken manure being discharged into the River Wye, previously one of the most beautiful rivers on our island. At Second Reading, the noble Earl, Lord Shrewsbury, reminded us about the discharge of raw sewage into rivers. As one of her first duties, the newly elected MP for Chesham and Amersham, Sarah Green MP, has visited the River Chess to hear from the local action group about the pollution of it.

During lockdown, with local authority swimming pools closed to the public, those who were able took to what has become known as wild swimming in the sea and rivers. I am assured that this is extremely invigorating and refreshing, but probably not so if you are encountering severe pollution on the scale that we have heard of from the noble Duke, the Duke of Wellington. Biodiversity is severely affected by the pollution in our rivers.

The treatment of sewage is the responsibility of the sewerage and water authorities. It is not sufficient for them to claim that new housing developments have overwhelmed their treatment plants and they have no choice but to discharge sewage into our rivers and sea. We have heard recently of the public disquiet about the Government’s proposals to change the planning laws. Often, statutory consultees respond to local authorities with “no comment”, but often they do not respond at all. Perhaps this is an issue of resources, with Defra cuts to the Environment Agency filtering down to the front line. The water authorities should be obliged to respond to consultation on proposed housing developments, especially where there is insufficient capacity in existing treatment plants to cope with the current, never mind the future, demand.

All noble Lords taking part in this debate have expressed concern on the issue of water quality. The Government must take it seriously if we are to restore the quality of the water in our rivers to enable biodiversity to increase, even if it is unlikely ever to reach its former levels. As the noble Baroness, Lady Young of Old Scone, and others have flagged, we will return to this in later amendments. This is a very serious matter, as my noble friend Lord Teverson and the noble Lord, Lord Cormack, said, and we fully support the comments of the noble Duke, the Duke of Wellington, in moving this amendment and look forward to the Minister’s response.

--- Later in debate ---

[Lord Randall of Uxbridge (Con) [V]]

My Lords, I will speak to my Amendment 10. I am grateful to my noble friends Lord Carrington and Lord Taylor of Holbeach, and the noble Baroness, Lady Bakewell of Hardington Mandeville, for signing it.

It is always a pleasure to follow the noble Lord, Lord Teverson. We spent quite a long time on the Fisheries Act, as it now is. I think I would say “marine” rather than “maritime” as a concept—“maritime” has more connotations to do with ships and so forth. But “marine” and “terrestrial” also join together, and of course, there are the shores. This issue could be solved, quite frankly, by my noble friend the Minister making it quite clear exactly what is covered by this.

Amendment 10 deals with light pollution, which has increased from a variety of sources, including domestic residences, public infrastructure—particularly lighting along roads and motorways—and industrial activity, such as energy infrastructure. Much of the earth’s population is affected by light pollution. Some 80% of the world’s population now live under sky glow and nearly every European cannot experience a natural night sky from where they live. I have not seen the night sky properly where I live—except possibly in a power cut—but when I occasionally go up to Norfolk, along the coast I am blessed to be able to see the night sky in all its glory.

In recent years, evidence of the impact of light pollution on species and ecosystems has grown and consolidated. Increased artificial light at night is directly linked to measurable negative impacts on energy consumption, obviously, human health and wildlife such as bats, birds, insects and plants. Unnecessary artificial light increases financial costs and contributes to greenhouse emissions. Light pollution should be treated with the same disdain with which we treat all other forms of pollution.

Among other organisations that I belong to, I am a member of Buglife, a charity devoted to the protection of insects. I am pleased to say that this week is National Insect Week. Studies from Germany suggest that a third of insects attracted to street lights and other fixed light sources will die. This results in the death of an estimated 100 billion insects in Germany every summer. Light pollution is reducing nocturnal pollinator visits to flowers by 62%, in some areas. Again, to show my slightly nerdy side, from time to time I put out a moth trap, but mine is not as successful as those of some of my friends elsewhere, who do not have the same light amount of light coming in from other sources. We know that moths are attracted to light, but that it confuses some.

Glow-worms use luminescence to attract prey and mates. Artificial light can affect their ability to do both. Evidence shows a decline in the abundance of glow-worm populations with increased proximity to artificial light.

Birds that migrate or hunt at night navigate by moonlight and starlight. Artificial light can cause them to fly towards lit areas. Recent research shows more birds migrating over urban, rather than rural, areas. This deviation from traditional routes can have a significant impact on energy levels during migration and lead them to stop in suboptimal habitats.

The US recognises bird strikes against high-rise buildings as a real problem. In Texas, the former First Lady Laura Bush heads a lights-out campaign, twice a year, to encourage high-rise buildings to switch off their lights, so that they do not kill all these migratory birds. Some of the photographs you see of the carnage caused underneath these high-rise buildings are disturbing.

Artificial lighting can cause many problems for bats, including disrupting roosting and feeding behaviour and their movement through the landscape. In the worst cases, it can directly harm these protected species. As all bats in the UK feed on insects, loss of food sources is also a considerable threat.

For us humans, light pollution is negatively impacting astronomy and our ability to observe the stars. To look up on a cloudless night and see the stars is one of the more uplifting pleasures that we can have from childhood onwards.

Many marine species such as crabs and zooplankton are attracted to artificial lights near the shore, from ports or gas facilities, which can disrupt feeding and life cycles. Many noble Lords will have seen, in one of the more recent David Attenborough programmes, the disturbing sight of turtles coming to shore when they are hatched instead of going out to the sea. They are designed to be attracted to moonlight, but are going towards cafes and restaurants, with all their lights, crossing roads and perishing. This is a real problem.

The British Astronomical Association estimates that 90% of the population of the UK are unable to see the Milky Way from where they live. Evidence shows that light exposure at the wrong time has profound impacts on human circadian rhythm, affecting physical and mental functions. Artificial lighting has been linked to trees bursting their buds more than a week early, a magnitude similar to that predicted for 2 degrees centigrade of global warming.

My amendment aims to set a commitment to act on matters that relate to light pollution currently omitted from the Environment Bill. I hope it ensures that the Government produce targets to reduce levels of light pollution in England. The evidence is clear that light pollution has a significant impact on the normal activity of invertebrates, birds, bats and plants, and that these impacts are more than sufficient to require action. It would be a failure not to address this before we have long-term data and doing so would go against the Government’s draft environmental principles, in particular the precautionary principle, but also the prevention and rectification-at-source principles.

The UK does not yet report on light pollution levels. However, measuring light pollution is simple. Satellite images can be used to establish pollution levels and the CPRE has developed a nine-band classification system that could form the basis for monitoring change. Existing policy on light pollution does not provide sufficient guidance and is not strong enough to tackle its increasing impact. Several countries have introduced national policies on light pollution, such as Germany, France, Mexico, South Korea, Croatia and Slovenia. When I was last in France, I noticed that some villages have the designation “village étoile”, which they relish, because people go to them specifically to see the night sky.

The UK’s Environmental Protection Act 1990, as amended, provides local authorities with statutory nuisance powers to address light pollution, but only when harmful to humans or if it “unreasonably and substantially” interferes with the use or enjoyment of a home or other premises. I am afraid this has not resulted in a reduction in general light pollution. The National Planning Policy Framework offers little consideration of light pollution. The only reference states:

“Planning policies and decisions should … limit the impact of light pollution from artificial light on local amenity, intrinsically dark landscapes and nature conservation.”


The last comprehensive consideration of the issue by the Government was the Royal Commission on Environmental Pollution’s 2009 report, Artificial Light in the Environment. However, I am afraid that almost none of its recommendations has been implemented.

On national targets, Clause 1 of the Environment Bill provides power for the Secretary of State to “set long-term targets” by regulation, in relation to

“(a) the natural environment, or (b) people’s enjoyment of the natural environment.”

Subsection (2) requires the Secretary of State to set long-term targets in the four priority areas of air quality, water, biodiversity and resource efficiency and waste reduction.

I strongly believe that light pollution should be considered a priority area too, so that the Government are required to set a long-term target to reduce its impact on nature and people’s enjoyment of it. This amendment is designed to achieve that outcome. A national plan intended to prevent, limit and reduce light pollution must include a series of targets and a programme of monitoring. National targets should be set to include no net increase in light pollution and an ambition to increase the number of dark sky reserves.

Finally, I support Amendment 11 in the names of the noble Baroness, Lady Bennett of Manor Castle, and the noble Lord, Lord Whitty. I have my own amendment later in the Bill, Amendment 112, on soil quality, which is as fundamental as anything in the Bill.

[Lord Harries of Pentregarth (CB) [V]]

My Lords, I have two amendments in this group. The later one, Amendment 31, concerns the health of our trees and the first, Amendment 12, planting new trees. It requires the Government to put before Parliament an annual report on the progress made towards achieving the initial target of planting new trees.

The extent and health of what is left of our forests, woodland and trees is a matter of deep concern. We all know the essential role trees play in absorbing carbon dioxide from the atmosphere, thereby making a vital contribution to slowing down climate change. A mature tree absorbs carbon dioxide at the rate of 48 pounds per year. In one year, an acre of forest can absorb twice the CO₂ produced by the average car’s annual mileage. We know in our personal lives how fundamental our trees are for physical health, aesthetic satisfaction and our spiritual well-being.

The Committee on Climate Change has said that we need to raise our current 13% forest cover to 17% by 2050 if we are to have any chance of meeting our climate goals. At the moment, the Government are missing their tree-planting targets by 40 years. If we continue at the current slow rate of tree planting, the Government’s own 2050 targets will not be met until 2091. As those figures show, the number of trees planted each year needs to be very significantly increased.
