Australia’s carbon credit market reached record transaction volumes in August 2025, but dig into the data and you’ll find a market that’s fragmented, opaque, and difficult for most companies to navigate effectively. ACCUs (Australian Carbon Credit Units) from similar project types trade at price differences of 20-30% depending on who’s buying and who’s brokering.

Price Discovery Is Broken

There’s no central exchange for ACCU trading. Most transactions happen through bilateral agreements or brokers, with limited public price reporting. The Clean Energy Regulator publishes auction results, but private market trades—which represent about 70% of total volume—remain largely invisible.

We’ve tracked public reports and industry contacts to map pricing for different ACCU types. Savanna burning credits from Northern Territory projects trade anywhere from $32 to $42 per unit. Soil carbon credits range from $28 to $38. These aren’t small variations on low-value commodities; they represent significant cost differences for companies trying to offset emissions at scale.

Why It Matters for Business

Any company with Scope 1 or 2 emissions reduction targets will likely need to purchase offsets at some point. If you’re paying 25% more than necessary because your procurement team doesn’t understand market dynamics, that’s a material cost that flows straight to the bottom line.

The problem intensifies for companies new to carbon markets. Brokers know which buyers are sophisticated and which aren’t, and pricing reflects that information asymmetry. A mining company buying 50,000 ACCUs for the first time will almost certainly pay more than a large energy retailer with established market relationships.

Project Quality Variations

Not all ACCUs are created equal, which partially explains price differences. Some projects face higher permanence risk—the chance that stored carbon gets released back into the atmosphere. Vegetation projects in fire-prone areas carry more risk than engineered landfill gas capture. Buyers concerned about reputational risk pay premiums for projects with robust methodologies and strong co-benefits.

The market’s starting to differentiate between commodity ACCUs (bought purely for compliance) and premium credits with verified social or environmental co-benefits. Indigenous-led savanna burning projects command higher prices because buyers value the cultural and biodiversity outcomes alongside carbon reduction.

Comparison to New Zealand’s ETS

New Zealand’s Emissions Trading Scheme operates differently. NZUs (New Zealand Units) trade on an exchange with transparent pricing and daily settlement. While NZ’s market has its own issues—particularly around forestry offset quality—at least buyers can see what they’re paying relative to market rates.

Australian businesses operating across both countries notice the difference immediately. Procuring NZUs is straightforward: check the spot price, execute the trade, settle within two days. Procuring ACCUs requires broker relationships, negotiation, due diligence on project credibility, and hope that you’re not overpaying significantly.

Registry and Verification Challenges

The Clean Energy Regulator’s registry system wasn’t designed for high-volume, rapid trading. Transfers can take weeks to settle, creating counterparty risk and complicating financial planning. Companies can’t use ACCUs as liquid assets the way they might trade NZUs or international carbon credits.

Verification standards also vary more than they should. The Regulator audits projects, but sampling rates are low and some methodologies rely heavily on modeling rather than direct measurement. Buyers doing their own due diligence add time and cost to transactions, further reducing market efficiency.

What Could Fix This

Several market participants have proposed establishing a central exchange for ACCU trading, similar to futures markets for agricultural commodities. The Australian Securities Exchange explored this possibility but hasn’t moved forward, possibly due to concerns about market depth and participant appetite.

Technology could help. Better data aggregation, standardized contract terms, and blockchain-based settlement systems would all improve liquidity and price discovery. Some companies are already building these tools, though adoption remains limited.

Implications for Corporate Strategy

If your company’s developing a decarbonization roadmap, factor in carbon credit procurement complexity. Don’t assume you can buy ACCUs at whatever price shows up in consultant reports or government forecasts. Actual procurement will require either building internal expertise or engaging advisors who understand market dynamics.

Consider long-term offtake agreements directly with project developers. These contracts typically offer better pricing than spot market purchases and guarantee supply, but they require upfront commitment and due diligence on project viability.

For companies managing both operational efficiency and compliance requirements, it’s worth exploring whether team400.ai or similar specialists can help optimize your approach—this isn’t just a procurement problem, it’s a strategic planning challenge.

The Bigger Picture

Australia’s carbon market is still young compared to European schemes that’ve operated for nearly two decades. Growing pains are expected. But if the government wants business to embrace carbon reduction as part of normal operations rather than grudging compliance, market infrastructure needs to catch up.

Until then, companies should approach ACCU procurement with the same rigor they’d apply to any significant commodity purchase: understand the market, build relationships, verify quality, and never accept the first price offered.
