Environment Bill

Lord Krebs Excerpts

2nd reading
Monday 7th June 2021 Lords Chamber

[Lord Krebs (CB) [V]]

My Lords, this Bill is both welcomed and long overdue. It could give us the basis for reversing decades of careless mistreatment of our natural environment and the opportunity to enjoy cleaner air and rivers and restore degraded habitats and biodiversity.

As my noble friend Lord Cameron mentioned earlier, in 1973, when we joined the European Union, we were labelled the dirty man of Europe. We have made significant process since then, largely as a result of EU rules and enforcement, but there is still a long way to go. It is said that this Bill will help us go further, but I remain to be convinced. To explain why, I want to focus on biodiversity—or nature, as the noble Lord, Lord Blencathra, prefers to call it.

The UK is one of the most depleted countries in the world in terms of biodiversity. The Natural History Museum has calculated an index of biodiversity intactness. Using this measure of the health of our natural environment, we rank 189th in the world, and we are bottom of the G7 countries. In the past 10 years, 41% of our bird species have decreased and 15% of our wildlife is threatened with extinction. The dreadful state of our nature is at least in part a result of living in a densely populated country in which nearly three-quarters of our land is used for farming or the built environment. We have simply squeezed nature out of its home.

I am therefore very pleased to learn that the Government intend to introduce legally binding targets for restoring biodiversity through this Bill. However, the Government have set targets for halting nature’s decline before and failed to meet them. For instance, in 2010 the Government signed up to the so-called Aichi targets under the global convention on diversity. In 2019, the Joint Nature Conservation Committee found that we had made insufficient progress on 14 out of 19 targets. Furthermore, in 2020 the JNCC reported that only about half the sites of special scientific interest in this country are in favourable condition and that there has been no improvement in this score over the past 15 years. So, forgive me if I sound a bit sceptical, but I would like the Minister to explain why we should believe any new commitments to meet biodiversity targets, given the Government’s past record of failure.

At the same time, I hope the Minister can unpack a bit more of the detail. First, will the targets involve halting the decline of particular species, taxonomic groups or habitats, or all three? Secondly, do the Government know what actions they will have to take to restore nature? Many of the initiatives supported under Pillar 2 of the common agricultural policy failed to enhance nature because they were not based on good science—a point just made by the noble Lord, Lord Browne of Ladyton. Will the Government be able to avoid making the same mistakes? Where is the science going to come from?

Thirdly, how will the Government calculate the trade-offs that will inevitably have to be made? Creating more space for nature means less space for human activity, be it space for producing food, building houses, roads or businesses—a point made by my noble friend Lord Cameron of Dillington. Fourthly, and more particularly, proposed new Schedule 7A to the 1990 Act refers to a “biodiversity metric”. I hope the Minister can shed light on how this is to be calculated. For example, how many stone-curlews equal one purple emperor?

Last but not least, what the sanctions be if the Government fail to meet their biodiversity targets? We have been told that the new office for environmental protection will hold public authorities, including Ministers, to account. I share the Minister’s respect and admiration for the chair, Dame Glenys Stacey. However, as we have heard this afternoon, there is a tide of expert legal opinion that the Bill does not give the OEP sufficient powers or independence to fulfil its role. These points have been eloquently explained by my noble friend Lord Anderson of Ipswich and others. I would also like to acknowledge a meeting I had with the Minister, the noble Lord, Lord Anderson, and Tim Buley QC to discuss these points.

In sum, I like the declared intentions of the Bill. I know the Minister is committed to improving our environment, but there is still a great deal of work to be done to explain how this will be achieved. I look forward to working with him and other noble Lords as we debate and improve this important Bill.

Food Waste

Lord Krebs Excerpts

Wednesday 24th March 2021 Lords Chamber

[Lord Goldsmith of Richmond Park (Con) [V]]

The noble Baroness makes an important point. We are supporting WRAP, which is our delivery partner, to help the hospitality sector to waste less food. WRAP has developed a new programme, called Guardians of Grub, to help the sector put food waste reduction, with all the associated cost savings, at the heart of its operations. As I mentioned, we are also supporting the redistribution sector to get more surplus food to those in need. In 2018, the hospitality industry provided more than 1,000 tonnes of surplus food—around 2% of its total—and since then we have invested significantly in redistribution, so we expect those positive trends to continue.

[Lord Krebs (CB) [V]]

My Lords, given that the global food system accounts for as much as 30% of greenhouse gas emissions, does the Minister agree that food, farming, dietary change and tackling food waste should form part of the Government’s commitments for COP 26? Does he also consider that it would be appropriate for England to join Scotland in signing the Glasgow food and climate declaration?

[Lord Goldsmith of Richmond Park (Con) [V]]

My Lords, it is remarkable that over the last 40 years food production has trebled, but that has come at a huge cost, in soil erosion, in the unsustainable use and pollution of water and in deforestation. Agriculture is responsible for about 80% of the world’s deforestation and deforestation is now the second biggest source of emissions. Meanwhile, efforts to produce cheaper meat have led to industrial-scale use of antibiotics, which in turn exacerbates issues around antimicrobial resistance. This absolutely is a central issue and much of the work that we are doing in the run-up to COP 26 in November is centred around the need to shift and change fundamentally the way in which we use land.

Heather and Grass etc. Burning (England) Regulations 2021

Lord Krebs Excerpts

Thursday 18th March 2021 Lords Chamber

[Lord Krebs (CB) [V]]

My Lords, I thank the noble Baroness, Lady Jones of Whitchurch, for bringing forward this Motion, which I support. I will not repeat what other noble Lords have said about the ecosystem services provided by upland peat, such as flood protection, water purification and carbon storage, as well as its importance for rare species such as sphagnum imbricatum.

We are all critical of Brazil’s burning of the Amazon, but we are doing something similar to one of our most precious habitats of global importance. As other noble Lords have said, nearly all our upland peat bog has been damaged or destroyed by a combination of burning, overgrazing, drainage and pollution. The Climate Change Committee concludes that climate change will increase the rate of degradation and carbon loss from peat bogs and that only by restoring them to good condition now will we be able to benefit from their ecosystem services in the future.

Can the Minister say whether the proposed regulations follow the Climate Change Committee’s advice and, if not, why not? Some noble Lords have argued that burning is actually good for carbon storage. There is, indeed, dispute about the precise effects. I do not have time to go into the literature but let me quote Professor Peter Smith of Aberdeen University, arguably the UK’s leading expert on soil carbon. He states:

“While there might be some merit in the suggestions that peatland burning could lead to a longer term carbon storage, we know that peatland burning does lead to additional carbon release now. At a time when we should be focused on restoring peatlands to help meet our net zero by 2050 climate change targets, allowing peatland burning does not seem very compatible from a climate change perspective.”


Does the Minister agree with Professor Smith?

Trees

Lord Krebs Excerpts

Monday 25th January 2021 Lords Chamber

[Lord Goldsmith of Richmond Park [V]]

The noble Baroness makes a really important point, which relates to an answer I gave earlier about the multiple benefits of trees and woodlands. One area that we are looking at closely is the important role of natural colonisation or natural regeneration of land in increasing woodland cover. It encourages natural establishment of local trees, species diversity and better adaptation to local conditions. It supports a wider range of wildlife but also reduces the risk of importing tree disease—a point made earlier. It also reduces plastic tree guards—a terrible blight in many parts of the country—and is, on the whole, low-cost.

[Lord Krebs (CB) [V]]

My Lords, in the past half century, we have lost many trees to disease, including an estimated 20 million mature elm trees and a projected 100 million ash trees. What are the Government doing to ensure that we have sufficient research and expertise in tree diseases to keep ahead of future threats? Will the Minister tell us how many universities in England offer postgraduate education in tree pathology?

[Lord Goldsmith of Richmond Park (Con) [V]]

My Lords, I cannot provide a specific numerical answer, but will follow up with a written answer. We know that a large number of ash trees will become infected, but not all will die. We expect 1% to 5% of ash trees to show some tolerance to the disease, which is heritable, so we are funding research into a future breeding programme of tolerant trees. We are also conducting the world’s largest screening trials and will be planting the first tolerant trees this year.

Flooding

Lord Krebs Excerpts

Wednesday 20th January 2021 Lords Chamber

[Lord Goldsmith of Richmond Park (Con) [V]]

I believe that Defra, the Environment Agency and local emergency services are fully prepared to respond to any flooding alongside the response required to Covid-19. Extensive preparations are being made to operate flood defences and flood storage reservoirs and to put up temporary barriers where needed to protect communities ahead of the incoming weather. I just make the point that the Environment Agency has 25 miles of temporary flood barriers, 250 high-volume pumps, eight principal depots spread around the country, 6,500 staff trained and ready to respond and 1,500 military on standby to provide mutual aid. The Government’s preparations have been made and we are, we believe, fully prepared. I do not accept the noble Lord’s comments about the Environment Agency.

[Lord Krebs (CB) [V]]

My Lords, as a result of climate change, the sea level will rise and some of our coastal areas will be inundated in the coming decades. Have the Government assessed the eventual need to relocate some coastal communities due to flooding risk, and have they identified which are the most vulnerable? Related to this, do the Government have a policy on how much flood risk will be acceptable in future?

[Lord Goldsmith of Richmond Park (Con) [V]]

The noble Lord highlights an important point. We know that many of our coastal settlements are at risk if trends continue in the same direction. We are also investing, as part of our response and the £5.2 billion, £200 million to support more than 25 local areas to take forward wider innovative actions that improve their resilience to flooding and coastal erosion, with a big emphasis on nature-based solutions. I cannot provide the noble Lord with a numerical answer on the level of acceptable damage, but we are increasingly emphasising nature-based solutions, because we know that, in terms of pound-for-pound investment, that is where we are likely to see a very significant return. That is as true on the mainland as it is on the coast.

Burning of Peat Moorlands

Lord Krebs Excerpts

Wednesday 14th October 2020 Lords Chamber

[Lord Krebs (CB)]

My Lords, blanket bog, to which the Minister has referred on a number of occasions, is of course a great method of storing water and holding it back so that it does not go down into the valleys and flood towns and villages below. One consequence of draining sphagnum bog and turning it into heather moor or short grass is that people in the valleys suffer increased flood risk. Does the Minister have any figures to hand on the cost to this country of flood damage in the valleys to people and properties, as compared with the financial benefit of managing moorland by draining and having it as heather moor and short grass?

[Lord Goldsmith of Richmond Park (Con)]

It is extremely difficult to attach a particular flooding event to a particular cause, because there are so many causes, but the noble Lord is absolutely right that damage to the natural environment exacerbates flood risk. That is why as part of our flood strategy, which is being developed, there is a significantly increased emphasis on nature-based solutions to flooding. Part of that is planting trees in the appropriate areas; part of it also is restoring peatlands.
