Why Starting a Soil Carbon Project Now Makes Sense

Soil Health, Market Signals and Strategic Timing: Why Early Movers in Agriculture Are Gaining Ground

Soil health sits at the foundation of agricultural productivity and stability of our food systems. Healthy soils hold water, cycle nutrients, support biodiversity, and store more carbon than the world’s atmosphere and vegetation combined.

Globally, soil organic carbon (SOC) reserves to two metres depth are estimated at approximately 2,400 gigatonnes of carbon – nearly four times the carbon held in all vegetation worldwide and three times that held in the atmosphere.

Yet since the advent of agriculture, research suggests around 133 billion tonnes of carbon has been lost from soils. Intensive agriculture, land clearing, erosion and declining groundcover have significantly depleted these reserves.

Critically, this loss has occurred primarily from topsoil: the most valuable part of the soil profile. Topsoil is the plant‑accessible, biologically active layer where soil health is built. Losing topsoil carbon directly undermines the capacity of land to retain water and grow pasture, weakening the ecological foundations of food systems worldwide.

In this context, restoring soil carbon is not simply a land stewardship objective. It is increasingly understood as essential to maintaining productive, resilient farming systems.

Australia is in the enviable position of rewarding farmers for adding carbon to soils through a carbon trading scheme. While there are some strict requirements to the method, the rewards can be financially significant.

Therefore, the question is no longer whether soil carbon projects matter – but whether producers participate early enough to maximise their full value.

Soil Carbon and National Climate Policy

Australia’s commitment to lowering emissions by 2050 places agriculture and land use at the centre of national climate policy.

Unlike most sectors, agriculture has the ability to both reduce emissions and remove carbon from the atmosphere. This dual role positions it as one of the few industries with scalable, nature-based abatement opportunities available today.

Soil organic carbon sequestration is recognised in the Australian Government’s Long‑Term Emissions Reduction Plan and Agriculture and Land Sector Plan. The policy direction is clear:

  • Reduce emissions where we can
  • Increase carbon storage within productive landscapes
  • Maintain food and fibre output

This reflects a broader shift – climate action in agriculture (such as through carbon projects) is no longer framed as a trade-off with productivity, but as a driver of long-term performance and resilience.

How Soil Carbon Projects Fit This Framework

The Australian Carbon Credit Unit (ACCU) Scheme provides a regulated pathway for producers to generate carbon credits from verified emissions reductions or removals.

Each ACCU represents one tonne of carbon dioxide equivalent (tCO₂-e). Official Soil carbon projects registered with the Clean Energy Regulator (CER) use a prescribed measurement and modelling approach to quantify changes in soil carbon over time.

Where soil carbon increases over time against a baseline measurement, carbon credits (ACCUs) can be issued.

Importantly, this is a project-level outcome, not a whole-of-enterprise one.

  • ACCU-generating soil carbon projects measure net abatement relative to a defined baseline within the project boundary – not total farm emissions. Participation does not, by itself, equate to achieving net zero at the enterprise level.

However, there is an opportunity for soil carbon sequestration to offset farm emissions. This requires calculating your total farm emissions (Scope 1, 2 and 3), so that they can be effectively “inset”.

This distinction is critical, particularly as carbon metrics become more visible in market and reporting contexts.

Another opportunity is “offsetting”, where a producer sells carbon credits to an “emitter”. Emitters are generally large companies or facilities (think mining, electricity production, etc), that are making an effort to reduce their emissions over time. If they cannot completely reduce their own emissions, emitters can purchase ACCUs to make up the gap. In this case, they can buy credits from landholders who have pulled carbon out of the atmosphere, to ensure their extra emissions are “offset”.

From Theory to Verified Results

Historically, many producers have viewed carbon projects as a future consideration – something to revisit once methodologies, markets, or technologies had matured.

That perception is changing.

Across Queensland and New South Wales, soil carbon projects across grazing and cropping have now completed first – and in some cases second – measurement cycles, with verified ACCU issuance.

These outcomes shift soil carbon from concept to demonstrated performance.

For producers, this provides two forms of validation:

  • The methodology is measurable and auditable
  • Soil carbon projects can operate within commercial grazing and cropping systems

Verification converts interest into confidence.

Carbon Performance Is Becoming a Market Signal

Beyond policy and methodology, a broader shift is underway.

Discussion is ever-evolving around how agricultural businesses are assessed and valued, and the influence of measured environmental performance (particularly from carbon farming projects). This includes:

  • Supply chain preferences and procurement decisions
  • Lender and insurer perspectives on risk and resilience
  • Expectations around sustainability reporting and disclosure

In terms of sustainability reporting, soil carbon measurement provides producers with defensible, audited data that can support future environmental positioning – rather than relying on estimates or generic benchmarks.

As mandatory requirements continue to emerge, voluntary disclosure and verified abatement data positions producers ahead of the curve.

Immediate Operational Benefits

One of the reasons soil carbon projects are gaining traction is that their benefits extend well beyond carbon credit generation.

Producers undertaking soil carbon measurement frequently report improvements in:

  • Groundcover and pasture persistence
  • Rainfall infiltration and reduced runoff
  • Soil structure and water-holding capacity
  • Drought resilience and seasonal stability
  • Increased carrying capacity

These outcomes are not incidental.

The management practices that build soil carbon – maintaining groundcover, optimising rest and stocking rate, supporting living root systems, and addressing soil constraints – are the same practices that underpin productive and resilient farms.

In this sense, carbon becomes a measurable indicator of system health, not a separate objective.


Industry data supports this trend. Resource Consulting Services (RCS), working with extensive grazing businesses over four decades, reports average returns of ~40% on fencing and water infrastructure investments used to optimise grazing systems – often with payback periods of around 2–3 years.

Importantly, these investments are typically justified on production gains alone, with carbon outcomes representing an additional upside rather than the primary driver.

The Strategic Case for Starting Now

For producers weighing timing, the question is less “Will soil carbon matter?” and more “What position do I want to hold when it does?”

Starting a soil carbon project today positions producers to:

  • Establish baselines before further soil change or lost opportunity
  • Capture early-cycle sequestration gains
  • Build operational and reporting capability ahead of tighter market expectations
  • Generate verified data that can support future commercial positioning

Soil carbon farming participants are not only optimising their practices – they are building familiarity with the systems, metrics, and expectations that are increasingly shaping agriculture.

A Tool for the Transition – Not the Entire Solution

Soil carbon is not a complete solution to delivering net zero agriculture – but it is one of the most immediate, scalable and commercially aligned tools available to the sector today.

It sits at the intersection of:

  • Climate response
  • Farm productivity
  • Market access and evolution
  • Long-term land resilience

For this reason, Soil Carbon Farming is a strategic decision, not a speculative one.

Starting a soil carbon project is not about chasing a trend.

It is a considered decision about positioning, within a system that is already shifting across policy, markets, and the physical performance of agricultural land.

Producers who move early are not only participating in this change – they are better placed to shape and benefit from it as it accelerates.

Frequently asked questions about soil carbon and productivity 

Does soil carbon farming actually improve productivity? 

Yes. When projects are built around good land management, productivity improvements are often part of the outcome. Better soil function can support stronger pasture growth, improved water use, healthier ground cover and more resilient grazing systems. CarbonLink reports that many participating producers have seen productivity improvements alongside soil carbon outcomes.

Will a soil carbon project restrict how I run my farm?

No, soil carbon projects are designed to work alongside farm production, not replace it.

While projects involve monitoring and reporting requirements, practice changes are intended to support long-term productivity, drought resilience and stronger land condition rather than limiting day-to-day decision-making.

Does soil carbon work for livestock businesses only?

No. Soil carbon projects can apply across grazing, cropping, mixed farming and pasture-based systems. 

The objective is not a one-size-fits-all model. Projects are designed around the operation, land type and management flexibility required.

What practice changes help build soil carbon?

There isn’t one formula.

Eligible practice changes can include:

  • Changing grazing intensity or stocking strategy
  • Rejuvenating or establishing pasture
  • Introducing legumes or cover crops
  • Improving irrigation efficiency
  • Retaining stubble
  • Moving toward reduced tillage
  • Applying soil amendments where appropriate
  • Improving landscape function and water movement

Projects are designed around what suits each farm, rather than prescribing one method.

I’m already doing regenerative practices, does that mean I’ve missed the opportunity?

Not necessarily.

A higher starting point doesn’t automatically mean lower returns. Existing regenerative management may create healthier, more biologically active systems that still have capacity to continue building soil carbon over time.

Eligibility depends on demonstrating a meaningful step-change compared with historical management, not starting from poor conditions.

What happens if I don’t build carbon in the first reporting period?

If no ACCUs are issued, there is nothing to repay.

In practical terms, the main downside is the cost associated with measurement during that reporting round.

While outcomes can vary, consistent application of your selected practice changes – combined with CarbonLink’s strong track record and specialised approach to project design, sampling, and measurement – means it is highly unlikely that you would not demonstrate an increase in soil carbon over time.

Why choose soil carbon over other carbon project types?

For many producers, soil carbon stands out because it can work alongside normal farm production.

Rather than changing the purpose of the land, the goal is to strengthen resilience, support productivity and potentially create an additional income stream through measured improvements in soil carbon.

How can I get started with a soil carbon project?

Start by understanding whether a soil carbon project aligns with your property, management approach and long-term goals.

Many of the practices that support soil carbon are already recognised as good farming principles.
