When Nature Became an Asset Class

When Nature Became an Asset Class

First Britain put a new value on land for energy. Now biodiversity, carbon, habitat and environmental restoration are acquiring prices of their own. Government wants more than £1 billion a year of private money flowing into nature by 2030. The question is familiar: who owns the land, who captures the new income — and what happens to the person already farming it?

By Shane Oxer

There was a time when the economics of a field were relatively easy to understand. A farmer planted wheat, grazed cattle, cut hay or rented the acreage to somebody who did. The value of the land ultimately depended, in large part, on what could be produced from it.

Britain is now constructing something altogether different. The same field can potentially produce food, solar electricity, biodiversity units, carbon benefits, nutrient mitigation, flood protection or other environmental services. Government policy increasingly gives those services an economic value, private investors are being encouraged to finance them, and landowners are being offered new ways to make the countryside pay.

Nature, in other words, is becoming an asset class.

The language used by government is considerably gentler. It speaks of nature recovery, public goods, green finance and environmental markets. Much of what those policies seek to achieve is perfectly defensible. Britain has lost habitats and species. Rivers need restoring. Peatland can be damaged. Hedgerows and woodland matter. There is nothing wrong with paying somebody to improve the environment.

But once government creates a market around an environmental outcome, another question immediately follows. Who owns the land capable of supplying it?

That question matters because Britain has already discovered through the solar expansion that the person working a field and the person owning it can be entirely different people. Net Zero made the distinction economically important. The natural-capital economy may make it more important still.

Thirty-by-thirty is the obvious place to begin. The UK has committed to effectively conserve and manage 30 per cent of land and sea for nature by 2030. In England, the Government’s new delivery plan, published in July, contains an important reality check. Only around 7 per cent of England’s land currently meets the Government’s 30by30 criteria. Its analysis says land covering about 32 per cent of England either already appears likely to qualify or has the potential to contribute, but getting from seven to thirty requires a dramatic acceleration over the remaining four years.

This is not, as sometimes claimed, a law allowing Whitehall simply to confiscate 30 per cent of England. The current assessment process for additional land is voluntary. That fact should be stated plainly. But what government proposes to do to encourage participation is far more interesting than the caricature of a compulsory land grab.

The official delivery plan says long-term habitat protection must represent a “financially viable option for land managers” if they are to participate. It promises to reduce barriers by increasing incentives, aligning funding streams and making it easier to combine public and private investment. It also talks about using guarantees, first-loss capital, procurement and tax mechanisms to reduce the risk to early private investors.

That is not merely a conservation programme.

It is the construction of an investment environment.

Government has gone further still. Its Green Finance Strategy set an explicit goal of mobilising at least £500 million a year of private finance into nature recovery in England by 2027, rising to more than £1 billion every year by 2030. The money is expected to flow into activities including carbon sequestration, flood management, water quality and compensation for biodiversity and nutrient impacts.

One billion pounds a year does not arrive because investors suddenly become charitable.

Capital expects a return.

That means nature recovery requires something capable of producing an income stream, and Britain has begun constructing precisely such markets.

Biodiversity Net Gain is perhaps the clearest example. In England, most qualifying development has to deliver a biodiversity improvement of at least 10 per cent. A developer unable to provide all of that improvement on its own development site can purchase biodiversity units created elsewhere. Government guidance explicitly tells landowners, farmers, estate owners and habitat-bank operators how to create those units and sell them to developers.

Pause there for a moment.

A developer wants to build houses, warehouses or other development.

The planning system requires additional biodiversity.

Somebody elsewhere owns land capable of providing it.

That owner or land manager can enhance habitat, register the resulting biodiversity units and sell those units into a private market.

The field has acquired another product.

It no longer produces only wheat or beef.

It can produce regulatory compliance.

The habitat created or enhanced for off-site BNG must generally be maintained for at least 30 years and secured through a legal agreement such as a Section 106 obligation or conservation covenant. Government makes clear that the landowner is legally responsible for delivering and managing the habitat over that period.

Thirty years.

For a Treasury official or fund manager, that is a contract duration.

For a farmer, it can be most of a working lifetime.

And the financial values are no longer theoretical. Defra’s statutory biodiversity-credit system — the deliberately expensive last resort for developers unable to obtain sufficient biodiversity gains elsewhere — currently prices a low-distinctiveness habitat credit at £42,000, hedgerow credits at £44,000, watercourse credits at £230,000, and certain high-distinctiveness lake credits at £650,000 each. Developers using statutory credits must also buy two credits for every biodiversity unit they need because of the spatial-risk multiplier.

Those are not private-market prices and should not be presented as such. Government deliberately sets statutory credit prices high so they do not undercut private suppliers. But that is precisely what makes the figures so revealing.

Government has deliberately constructed a system in which biodiversity can be measured in units, legally secured, registered, allocated to development and assigned a monetary value.

The language sounds as though it belongs in an ecology textbook.

The machinery looks increasingly like finance.

There are registers. Metrics. Buyers. Sellers. Brokers. Habitat banks. Legal covenants. Thirty-year liabilities. Prices. Credits. Investors.

Nature has entered the balance sheet.

And where there is a balance sheet, ownership matters.

Government guidance says biodiversity units can be sold on land you own or on somebody else’s land with the owner’s permission. A landowner or qualifying leaseholder can register a gain site, but the legal agreement securing the environmental obligations has to survive for the required period. Conservation covenants can bind future owners and, on freehold land, can even continue indefinitely where no duration has been specified. If land is rented, official guidance says those establishing the covenant should ensure the tenant has consented or agreed to become a party to it.

The reason for that caution is obvious.

A conservation agreement can affect what may be done with a farm long after the current tenancy has ended.

This brings us back to the person with whom this series began: the tenant farmer.

England’s own Land Use Framework acknowledges that 32 per cent of English agricultural land — around 2.9 million hectares — is managed by the tenanted sector. More remarkably, the Government concedes that policy has historically been “designed for owner occupiers”, leaving tenants locked out of opportunities created by changing land use. It now says a just transition requires tenants to remain on the land and gain access to the value created by those changes.

That is a remarkable official admission.

Because it describes almost exactly the structural problem this investigation has uncovered.

The tenant possesses the agricultural business.

The owner possesses the asset whose alternative uses may suddenly become much more valuable.

Solar demonstrated the problem first. An estate could discover that a field generated far more rent under solar than under agriculture. The tenant’s business might depend upon farming it, but the underlying opportunity belonged to the freeholder.

Natural capital creates another suite of opportunities.

If the field can generate biodiversity income, who gets it?

If woodland creation attracts carbon finance, who owns the carbon rights?

If peat restoration attracts investment, who signs the agreement?

If land is entered into a long-term conservation covenant, whose balance sheet receives the money and whose farming choices are restricted?

The Government-appointed Rock Review of tenant farming saw the danger years ago. It recommended that environmental schemes should be designed around the principle that tenants should not automatically require landlord consent where the scheme fits within the length and terms of their tenancy — and, equally, that landlords should not be able unilaterally to enter tenanted land into schemes over the heads of tenants.

That recommendation was not an obscure technicality.

It was recognition that a new market in environmental land use could reopen one of the oldest power imbalances in rural Britain.

Who controls the land?

The Government’s 30by30 plan now places large estates directly within the delivery architecture. It has created a National Estate for Nature grouping and says large landowners in that group have been asked to screen their holdings for present and potential contributions to 30by30. Members are being asked to update estate-management plans so newly created and restored habitat can enter the 30by30 pipeline. The Government explicitly says that the extensive holdings of these estates give them the capacity to drive nature recovery at scale.

Once again, concentrated ownership has advantages.

The same feature that makes a great estate attractive to a solar developer makes it useful to national nature policy: scale.

One estate can deliver hundreds or thousands of hectares under a coordinated management plan. One landowner can sign agreements affecting an area which might otherwise require negotiations across dozens of separate holdings.

For biodiversity, as for energy, Britain’s historic ownership pattern can make large-scale land-use transformation easier to organise.

That does not mean every great estate is exploiting the system. Many have managed woodland, wetlands and habitats for generations and will genuinely improve biodiversity.

The important point is economic.

When the Government sets a national target, creates incentives to meet it, encourages private capital into the market and asks large landowners to bring estate-scale holdings into the programme, ownership acquires a new type of value.

The asset does not merely appreciate because somebody wants to build houses on it.

It can appreciate because somebody wants the environmental services attached to it.

Scotland is constructing its own version of the same model. NatureScot’s Nature30 system allows landowners or managers to nominate qualifying areas for recognition towards Scotland’s 30by30 commitment. NatureScot explicitly says that recognition should provide a route to attracting private or public financial incentives to support management.

Wales is doing something strikingly similar. Its updated 30by30 framework describes qualifying OECM areas as Naturfa sites. Recognition itself is not a new regulation imposed on landowners, but the Welsh Government says it provides a foundation for attracting further public and private investment into nature recovery.

The vocabulary changes across the border.

The financial logic does not.

Recognise environmental value.

Secure it over time.

Attract capital.

Pay for outcomes.

This is how a modern market is constructed.

There is nothing automatically wrong with that. Somebody has to pay to restore peat, plant woodland, manage species-rich grassland and improve rivers. If private investors are willing to supply capital that would otherwise come from taxpayers, there can be genuine public benefit.

But investors do not usually invest simply because butterflies are attractive.

They require measurable outcomes, legal rights and anticipated returns.

Government understands that. That is why it talks about making conservation financially viable, de-risking private investment and building nature markets capable of scaling.

The danger is not that somebody has discovered a way of paying for environmental improvement.

The danger is that Britain quietly changes what land is for according to whichever policy-created income stream produces the highest return, while treating the people who presently use the land as secondary considerations.

We have already seen where that can lead in energy.

The agricultural rent cannot compete with the solar rent.

The tenant cannot compete with the infrastructure fund.

A 40-year energy lease may be described as temporary, but it is an entire farming generation.

Now add nature markets.

Agricultural income may one day be compared not merely with solar rent, but with biodiversity-unit income, carbon payments, nutrient credits, public environmental schemes and private conservation finance.

Government itself encourages the combination of compatible public and private environmental payments where double funding is avoided.

The farmer is no longer simply deciding what crop to plant.

The owner is deciding which economic function of the landscape produces the best return.

That distinction becomes important when food production is treated as though it were simply one optional land use among many. Farms are businesses with machinery, buildings, labour, livestock, supply chains and accumulated knowledge. Removing 100 acres from a 200-acre farm does not merely change the colour on a land-use map. It can change whether the remaining enterprise works at all.

A biodiversity investor looking at the same 100 acres may see something different.

Units.

Credits.

Habitat uplift.

Thirty-year cashflows.

Portfolio diversification.

This is why language matters.

A countryside described entirely through “natural capital” is subtly different from a countryside described as farms, woods, rivers and communities.

Capital is something to be valued, allocated, traded and made productive.

Once nature becomes capital, somebody will inevitably ask what return it produces.

The Government is no longer coy about wanting that market to grow. Its stated ambition is more than £1 billion of private finance into nature every year by 2030. BNG creates a compulsory source of demand from development. Nature markets are intended to attract private investors. Thirty-by-thirty creates a national direction for long-term land management. Large estates are explicitly being asked to align their plans with it. Scotland and Wales are creating their own routes to attract private and public finance around recognised conservation land.

The architecture is taking shape in plain sight.

And then, from 2 November 2026, the circle becomes tighter still: Biodiversity Net Gain will also apply to nationally significant infrastructure projects in England. The giant infrastructure developments reshaping land for the energy transition will themselves enter the statutory BNG system.

Think about the circularity.

Policy drives large infrastructure.

Infrastructure changes land.

The same development creates a requirement for biodiversity improvement.

If that improvement cannot all be delivered on site, developers may buy environmental units generated on other land.

A second land market is therefore created partly by the consequences of the first.

The solar farm needs fields.

Its biodiversity obligation can create demand for somebody else’s fields.

The energy transition and the natural-capital economy begin to feed one another.

Again, none of this proves corruption or conspiracy.

It proves something much more important.

Government policy is creating new forms of economic value attached to control of land.

That value will be captured by somebody.

The proper question is who.

If an owner-farmer creates habitat and receives the resulting income while keeping a viable farm, that may be an excellent outcome.

If a tenant shares fairly in the value created from land they manage, that deserves recording too.

If environmental investment restores genuinely degraded land while supporting rural communities, there is a public benefit.

But if a great estate can collect a new environmental income while a tenant loses productive acreage, or if land becomes more valuable as a bundle of biodiversity and carbon contracts than as the foundation of a working farm, the distributional consequences deserve exactly the same scrutiny we have applied to solar.

Because the great transformation underway in Britain’s countryside is no longer simply about generating electricity.

It is about creating new economic identities for land.

The field can become an energy asset.

The hedgerow can become a biodiversity unit.

The peatland can become a carbon project.

The river margin can become an environmental service.

The whole estate can become part of a national nature-recovery strategy.

And each transformation creates contracts, rights and income.

The person who owns the underlying asset enters those negotiations from the strongest position.

The person who merely works it does not.

That is why 30by30 should not principally be investigated as a mythical government plan to seize 30 per cent of the countryside. The truth is subtler and potentially much more consequential.

The Government does not necessarily need to own the land.

It needs owners to make participation financially attractive.

Private capital does not necessarily need to buy the land either.

It needs contracts giving it exposure to the environmental value produced by it.

The freeholder can retain the asset.

The investor can receive a return.

The state can record another hectare towards its environmental target.

And the tenant can still be the person standing in the middle wondering what happened to the farm.

That is the next stage of Robin Hood in Reverse.

First we financialised energy.

Now we are learning how to financialise nature.
