Understanding ACCU prices is essential for Australian businesses navigating the transition to a low-carbon economy. Just like electricity contracting and renewable PPAs, carbon procurement requires strategic timing, diversification, and expert advice.
By working with Energy Action, businesses can optimise their approach to ACCUs—reducing risks, lowering compliance costs, and demonstrating sustainability leadership.

Australian Carbon Credit Units (ACCUs) play a central role in the country’s carbon market, helping businesses offset emissions and achieve compliance with government requirements. As Australia moves towards its net zero targets, ACCU prices have become an increasingly important factor for companies looking to manage sustainability costs and carbon liabilities.
This article explores how ACCU prices are determined, why they matter to businesses, and what strategies can help organisations stay ahead in a changing energy and carbon landscape.
An Australian Carbon Credit Unit (ACCU) represents one tonne of carbon dioxide equivalent (tCO₂-e) stored or avoided through eligible emissions reduction activities. These can include:
Businesses use ACCUs in two main ways:
The ACCU price therefore directly affects the cost of doing business sustainably in Australia.
Much like LGC spot prices, ACCU prices are market-driven. They fluctuate based on several critical factors:
| Factor | Impact on ACCU Price |
| Government Policies | Changes in climate policy, Safeguard Mechanism settings, or carbon pricing rules can drive demand. |
| Supply of ACCUs | More eligible projects increase supply, often lowering prices; shortages push prices higher. |
| Corporate Sustainability Demand | Stronger ESG and net zero commitments increase voluntary demand, supporting higher prices. |
| International Carbon Markets | If linked to global markets, Australian ACCU demand and prices may rise. |
| Speculation and Trading Activity | Investor behaviour and trading dynamics can create short-term price swings. |
While ACCU prices have been less volatile than early LGC markets, they still show fluctuations influenced by regulation and demand.
| Year | Average ACCU Price (AUD) | Market Conditions |
| 2017–2019 | $15–$20 | Steady demand, modest project supply. |
| 2020–2021 | $20–$30 | Increased voluntary offsets, pre-Safeguard changes. |
| 2022 | $30–$55 | Policy shifts and corporate net zero strategies drove demand. |
| 2023–2024 | $30–$40 | Stabilisation with more project supply entering market. |
Note: ACCU prices are expected to fluctuate further as Safeguard Mechanism reforms deepen and more corporates pursue offsets.
Companies subject to the Safeguard Mechanism must surrender ACCUs if their emissions exceed baseline limits. Rising ACCU prices increase compliance costs.
Businesses aiming to be carbon neutral face higher costs when prices rise, impacting budgets for ESG initiatives.
Much like forward electricity contracting, timing ACCU purchases can lock in better value and reduce long-term risks.
Securing affordable ACCUs helps companies demonstrate climate leadership while maintaining financial responsibility.
Businesses can adopt several strategies to minimise risks and optimise costs:
Just as Corporate PPAs provide stability in electricity costs, structured ACCU purchases can hedge against future price spikes.
Sourcing ACCUs from a range of project types (forestry, agriculture, industrial) can balance risks.
Forward contracts or aggregated buying groups allow businesses to secure ACCUs at stable prices.
Reducing emissions directly can decrease reliance on ACCUs, cutting exposure to price volatility.
Advisors like Energy Action can help businesses assess carbon strategies, negotiate contracts, and align procurement with broader sustainability goals.
Looking ahead, several factors will influence ACCU pricing:
Overall, while prices may fluctuate, the long-term trend suggests steady or rising ACCU demand as Australia advances toward its climate commitments.

An Australian Carbon Credit Unit (ACCU) represents one tonne of carbon dioxide equivalent (tCO₂-e) reduced or stored through eligible projects. These credits can be used for compliance under the Safeguard Mechanism or voluntarily to offset emissions, supporting corporate sustainability and carbon neutrality.
ACCU prices are driven by market supply and demand. Factors include government climate policies, corporate offsetting demand, the availability of eligible projects, and international carbon market developments. Prices may also shift due to investor speculation and trading behaviour.
Businesses buy ACCUs to either comply with government regulations or voluntarily reduce their carbon footprint. For compliance, ACCUs prevent penalties under the Safeguard Mechanism. For voluntary purposes, they allow companies to showcase climate responsibility, meet ESG goals, and improve stakeholder trust.
While exact predictions are difficult, ACCU prices are likely to trend upwards as demand from both compliance and voluntary markets grows. Policy tightening and stronger net zero commitments could drive prices higher, though increased supply from new projects may soften some of this impact.
Businesses can manage risks by locking in forward contracts, diversifying their ACCU sources, reducing in-house emissions, and partnering with experts. Energy consultants help align carbon strategies with broader energy procurement, ensuring businesses get value while staying compliant and sustainable.
