Lord Fuller (Con)

My Lords, I want to speak strongly for Amendments 334, 346DD and 346DE in the name of my noble friend Lord Roborough. Two years after your Lordships’ House last considered nutrient neutrality, my noble friend’s amendments seek to break the nutrient neutrality deadlock, de-layer this cat’s cradle of conflicting regulations and allow us to focus on those things for best effort. Three and a half years ago, in 2022, nutrient neutrality rules were created, and then, at a stroke, they hunky-bunkered over 200,000 planning applications in over 75 planning authorities—planning authorities which for the most part have the greatest housing potential, because they are the ones clustered around the conurbations and thus have the greatest capacity to deliver housing growth. I was the council leader in one of these areas. At a stroke, together with our two neighbouring authorities, over 45,000 houses in a plan were made mute. We will never get roofs over people’s heads, including through affordable and social housing, while homes are not being built. My noble friend’s amendment gets to the heart of this; it allows us to ask the fundamental question as to whether stopping housebuilding will clean up our rivers. At the outset, let us be clear: the statutory responsibility for ensuring a clean environment falls variously upon Defra, the Environment Agency, Natural England—the statutory water undertakings for the effective running of sewage treatment works. These bodies have the funding, the powers and the responsibility for cleaning up our rivers, but the nutrient neutrality rulings transfer those responsibilities to a completely different class of organisation with no obvious statutory or financial resources to do so: local councillors, the planning departments of local planning authorities, and the housebuilding industry more generally. It is a buck-passing from those who should be designing and implementing solutions, in favour of the LPAs and builders who do not have any control over the matter at all. Taking all the homes in the UK, the Home Builders Federation estimates that, of all the current planning applications that would be built, it would add just 0.92% to the overall housing stock of 25 million dwellings. We have to consider materiality here. At this point, I feel I should declare that, when I was not leading a council in a previous life, my business was in the fertiliser industry. I have a degree in agriculture, I studied soil science, and I have built a career around advising on effective plant nutrition and the role of nutrients in soils. If I was on Mastermind, this would be my specialist subject. As I reflect on my own experience, it is now widely understood that the nutrient effect of the impact of new homes, over and above the existing homes in rural places such as Norfolk or Herefordshire, might contribute just 0.2% of the total phosphate load in a catchment. Put another way, out of 500 potential mitigating strategies, 499 are more likely to reduce phosphate emissions in a catchment than prevent new homes being built. In essence, not building a handful of homes in Holverston connected to a Klargester will not clean-up Rockland Broad, to give a very local example. It is important to restate why the restrictions have been imposed. The test in the habitats regulations and in law is to avoid “significant damage” to a special area of conservation—significant damage, not purely harm. I will never understand why we have stopped our second-largest economic sector, construction, and put tens of thousands of people out of work while serially sacrificing our housebuilding targets on the altar of nutrient neutrality—a marginal future gain of just 0.2%, when the problem exists here and now. We are aiming at the wrong target by stopping housebuilding. Just ask the people of the Hereford catchment of the River Wye whether building a few less homes will clean up their river, or whether the wholesale processing and removing of animal waste from the catchment might be a better approach. There, it is generally accepted that 80% of the nutrient load in places like Herefordshire comes from poultry manures—not from industry, or even existing homes; still less from homes that have not yet been built. Elsewhere in your Lordships’ House, the Environment and Climate Change Committee recently heard that over 20 million tonnes of sludges, slurries and digestates are applied to land from anaerobic digesters, and some of it on valley sides. I would venture to say that the Government would be better advised to focus on this issue, rather than stopping builders building. In essence, there is a dilemma. Do we focus on the 80%, or the 0.2%? That is why I like the noble Lord’s amendment. It enables us to focus our minds on where the substantive problem is. It directs us at the big numbers, not the trivial numbers. It stops us worrying about the 0.2% that might come from the building of new homes and from the flushing of their loos, damaging a significant contributor to the local economies and supply chains. Instead, the amendment seeks to allow a regulatory focus on where the real problem lies, which is principally with organic manures and digestates applied to land on bare stubbles, with nutrients which become mobilised much later in the summer, after harvest, when the ground has warmed up. The summer rains produce the ideal conditions to break them down into mobile phosphates, but not when the growing crops are there to absorb them, so they run off. If we focus on some of the bigger issues rather than the marginal ones, it might allow the Government to have a joined-up approach. We might even start to provide the grounds again for slurry schemes and storage, which were cancelled in the previous year; that is the key to handling the problem. The best chance of breaking this deadlock and getting new homes built quickly, as the noble Lord has said, is to take the rapier to Part 3 of the Bill and to work out how can we solve the problem, rather than misdirecting ourselves towards small harms. We need to address the big consequences that are harming our economy and our ability to grow, and to get roofs over the heads of the people who need those homes. These are not rich people. We need affordable housing, housing in villages, and housing on brownfield land. All this is hunky-bunker, and we must sweep it away and focus on the big target, not the little one.
