Carbon Farming: What Are the Legal Risks for Landowners?

Carbon farming can be a real income stream, but a carbon deal is a long term legal commitment, often 25 to 100 years, that attaches to your land and binds whoever owns it next. Before you sign anything, you need to know who owns the carbon credits, what you can and cannot do with your land for decades, and what happens if the stored carbon is lost. Get the agreement reviewed before you commit, not after.

A carbon developer knocks on the door with a good story. Earn money from your land for doing things that are good for the soil anyway. Plant some trees, change your grazing, get paid for the carbon. It sounds like found money.

Sometimes it is a genuine opportunity. But a carbon agreement is one of the longest commitments you will ever put on your land. Some run for a hundred years. That is not a decision to make on a handshake at the front gate.

Here is what every landowner should understand before signing.

What Carbon Farming Actually Is

Carbon farming means changing the way you manage your land so it stores more carbon, or releases less. That can be planting trees, protecting native scrub, changing how you graze, or building carbon in your soil. Carbon farming turns what your land already does into something you can sell.

The way you earn from it is through carbon credits. Do the approved work, prove the carbon is being stored, and you can be issued credits you can sell to businesses that want to offset their emissions. On the surface it is simple. Underneath it is a regulated scheme with strict rules and long tails.

The Rules Behind the Credits

In Australia, most farm carbon projects run under the Australian Carbon Credit Unit scheme, known as the ACCU scheme. It is administered by the Clean Energy Regulator under Commonwealth carbon farming legislation. One ACCU stands for one tonne of carbon dioxide stored or avoided.

The detail is where it gets serious. When you register a project you choose how long you will maintain the carbon, either 25 years or 100 years, and you cannot change your mind later. Choosing the shorter period means you are issued fewer credits. A portion of your credits is also held back to cover the risk that carbon is lost down the track. One credit stands for one tonne, and the rules behind it are strict.

Who Actually Owns the Carbon?

This is the question most landowners never think to ask. You own the land. But the carbon, and the credits that come from it, are a separate matter.

In New South Wales, the right to carbon stored in trees and plants can be held separately from the land title. It can be owned, sold or mortgaged on its own. So the carbon under your feet is not automatically yours to keep once a project is set up.

Many carbon developer contracts quietly take ownership of the credits, or a large share of them, in return for running the project. If you do not own the credits, you cannot choose when to sell, you cannot use them as security, and you lose much of the value the scheme was supposed to give you. Who owns the credits should be crystal clear, in writing, before you sign.

The Fine Print in Developer Contracts

Carbon project developers, sometimes called carbon service providers, offer to do the hard work for you. Some are excellent. But these are complex commercial agreements, and there is a catch most landowners miss. There is no standard carbon contract in this country.

Every developer writes their own terms, and those terms are written to suit them. The things that matter most are buried in the detail. Who is named as the responsible party to the regulator. Who owns and sells the credits. How the money is split, whether that is a fee you pay, a share of the credits, or all of the credits in exchange for a payment. How long the deal runs. What happens if the developer underperforms or goes broke. And what it takes to get out.

A weak agreement can lock you into decades of terms that favour the developer, on land that is your family’s single biggest asset. The contract is the whole game.

A Commitment That Outlasts You

This is the part that catches families out. Once credits are issued, a permanence obligation attaches to the land. You have to keep that carbon in place for the full 25 or 100 years you signed up for. A permanence obligation stays with the land, not just with you.

If the carbon is lost, through fire, drought, clearing or poor management, you can be required to hand back credits or buy replacements at whatever the market price is by then. In serious cases the regulator can place a carbon maintenance obligation on the property, which legally limits what you are allowed to do on that land.

Walking away early is expensive. To cancel a project after credits are issued, you generally have to buy equivalent credits on the open market, and the price may be far higher than what you were paid. This is a commitment measured in decades, not seasons.

The Risks Worth Understanding Before You Sign

None of this means carbon farming is a bad idea. It means you go in with your eyes open. The risks that matter most for farming families are practical ones.

You may be locking part of your land into one use for generations. You carry the risk if the carbon is lost, even from a bushfire you did not cause. A carbon agreement can shrink the number of people willing to buy your land, and cut the price when you sell. Your bank may need to agree before you sign, because the deal affects the security over your property. The biggest risk is signing away control of your land for longer than you can see.

Case Study: Looking Beyond the Annual Return

A landowner approached us after receiving a carbon farming agreement that offered an attractive annual income. On the surface, the proposal looked like a straightforward opportunity to generate additional revenue from part of the property.

After reviewing the agreement, we identified several provisions that could have significant long-term consequences. The project was proposed for a 100-year term, the developer would retain all carbon credit benefits, and there were extensive restrictions on future grazing and land management across a substantial portion of the farm.

By negotiating amendments to the agreement and helping the client fully understand the long-term implications, they were able to make an informed decision that better balanced immediate income with the future flexibility of their farming operation.

What It Means for the Future of Your Land

A carbon project does not just affect you. It reaches forward into the hands of the next generation. The child who takes over the farm inherits the obligation, the land use restrictions and the consequences if something goes wrong.

That is why a carbon decision cannot sit on its own. It needs to line up with your succession plan, your structure and your long-term goals for the land. A deal that looks good this year can quietly limit what your family can do with the farm for the rest of the century.

Case Study: Aligning a Carbon Project with the Family’s Succession Plan

One farming family entered into a carbon farming project before considering how it would fit within their long-term succession plans. Several years later, when they began transitioning ownership to the next generation, the obligations under the carbon agreement complicated the proposed structure and limited how parts of the property could be managed.

We worked with the family to review the agreement alongside their succession plan and ownership structure, helping them understand the legal obligations that would continue after the transfer. While the project remained in place, the family was able to adjust their succession planning to account for those commitments and provide greater certainty for the next generation.

Why a Legal Review Comes First

Carbon farming is not a farming decision or a financial decision alone. It is a legal one, and the legal terms decide whether it protects your future or ties your hands.

A specialist agribusiness lawyer can tell you who really owns the credits, what the agreement stops you doing, what happens on sale or on default, and whether the deal fits the rest of your plans. Have the agreement reviewed before you sign, not after. Once credits are issued, your options narrow fast.

Carbon can be a genuine opportunity for farming families. Done properly, with the right advice, it can add income while you protect your land and your legacy. Done on a handshake, it can cost you far more than it pays. The difference is the agreement, and who read it before you signed.
