According to the Government’s independent adviser on climate change, the Climate Change Committee, hedgerows are key to meeting our legally binding commitment to reach net zero by 2050. The committee has recommended increasing the length of hedgerows by 40% by 2050. Studies suggest that England’s hedges could already hold as much as 9 million tonnes of carbon. Unmanaged hedgerows are estimated to sequester over 140 tonnes of carbon per hectare, compared with 169 tonnes for a 30-year native woodland. If hedgerows are properly managed, they could sequester even more, both in their woody stems and in the roots below.

Whitehall could also be less prescriptive in the payments that it makes available to farmers. I would like to see more market-based payment rates for ELMS, reflective of our environmental needs and the demands from farmers. Options with the greatest environmental benefits or those with the lowest sign-up rates should have their payment rates boosted to increase uptake. To meet the Climate Change Committee’s recommendations to increase the length of hedgerows, SFI options for the planting and careful management of hedgerows should be included.

We have just found out that our Lib Dem-run district council will miss its 2030 net zero target after having reduced its greenhouse gases by only 16% in the last four years. I hope that the Government can facilitate our farmers in filling some of the gaps that the Lib Dems have left, and secure, enhance and extend our stunning network of hedgerows across North Devon and the country.

Hedges produce crops and provide food for people and animals. The protection and management of the natural environment is crucial for the agricultural sector and the environment, especially under the growing challenges imposed by the rise in temperature and the climate crisis, with continuing chaotic weather patterns. As a CPRE hedgerow champion—I am pleased that the hon. Member for North Devon mentioned us—I signed up to call on the Government to commit to significant hedgerow planting and restoration and to increase the extent of the UK’s hedgerows by 40% by 2050, as recommended by the UK Climate Change Committee. Under the nature recovery Green Paper, the Government have said that they are committed to protecting hedgerows, including through the ELMS scheme, but I would like to see them specify how they will encourage the creation of more.

When I attended the convention on biological diversity —the UN biodiversity conference—at COP15, Governments agreed a new set of goals for nature over this decade. Unfortunately, the UK is one of the most severely nature-depleted countries worldwide, and we have heard successive Government Ministers admit that that is the case. The Natural History Museum’s biodiversity intactness index, probably the best indicator of global biodiversity, has revealed that the world has crashed through the “safe limit for humanity” for biodiversity loss and placed the UK’s 53% score in the bottom 10% of all countries, well below China and last in the G7—not a record that we should be proud of. The Conservatives’ Environment Act 2021 target on species abundance, which they were forced to concede by Opposition amendments, promised only to “halt the decline” in species by 2030. Just halting the decline—or getting a “net zero for nature”—is not good enough. Our ambition should be to be nature-positive, both at home and when working internationally. Going forwards, we need to focus on improving our rewilding, reforesting and biodiversity targets in which hedgerows are preserved, utilised and renewed.

I am sure that my hon. Friend the Member for Cambridge (Daniel Zeichner) will tell us that Labour will take a different approach, which I will agree with. We need to be the change that we want to see. Action at home has showcased to the world how nature-positive policy can be practically delivered across Government. I am sure that my hon. Friend will tell us that Labour will have a robust, net zero and nature-positive test for every policy—we must do that now—and a green prosperity plan, with an investment of £28 billion in the latter half of the next Parliament, including funding for nature restoration. I hope that that green prosperity plan includes significant funding for the green skills needed for us to restore hedgerows and our nature-depleted environment.

A garden is a diverse landscape, which encourages multiple different plants and different layers to grow at different rates—but it is managed. The act of gardening, similar to farming, means that a garden is managed. Studies, especially those from the Royal Horticultural Society centre, RHS Wisley, now show that the benefits of our 30 million gardeners getting behind nature are absolutely phenomenal. We all know about the benefits of carbon sequestering, and if we are to fulfil our commitment of achieving net zero by 2050, gardeners will play a key role.

There are many things we can say, and I will say, about the transition to the new ELM schemes. For those who have been able to get into them, there is the prospect of local nature recovery. Many farmers and landowners are involved in the project from Kendal to Penrith, which will potentially provide a continuous corridor, much of which is based upon the extension and maintenance of hedgerows. It will bring huge benefit to our biodiversity, by tackling climate change, and by providing an improved home for nature. Let us be honest, they are important boundary structures and really effective for efficient land use.

10:24 The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Rebecca Pow)

Members really do not have to tell me how important hedgerows are, because I absolutely recognise that. The Government recognise that too. Many colleagues have mentioned the benefits we get from hedges: they provide habitats and wildlife corridors; they are great for holding the soil and stopping water run-off; they are wonderful habitats for our pollinators to shelter and hibernate in; and of course they sequester carbon. Interestingly, hedgerows were not planted for those reasons; started off as boundaries to keep our livestock in, but they have morphed into this wonderful feature that brings so many more benefits. They are so important to our landscape. They have also become important as we adapt to climate change, because they are part of our net zero commitment. They store carbon, and they are really valuable for that.

It is for all those compelling reasons that our environment improvement plan is supporting farmers to create and restore 30,000 miles of hedgerows by 2037, and 45,000 miles by 2050. That will enable all of those multiple benefits to be multiplied even more. We have calculated how much carbon can be sequestered by all those hedges, and we have the figure for 2037. It is interesting that my hon. Friend the Member for North Devon mentioned that her own Liberal Democrat council has failed its net zero target on hedges. It should probably look to its hedges and to see what it could do to get there. My hon. Friend is right: hedges can make a real difference on that agenda.
