Safeguard compliance pathways

When a Safeguard-covered facility's reported emissions exceed its baseline for a financial year, the Clean Energy Regulator (CER) requires the facility to surrender units equal to the shortfall. The facility has three surrender options: Australian Carbon Credit Units (ACCUs), Safeguard Mechanism Credits (SMCs), or Cost Containment Measure (CCM) units at the statutory price ceiling.

These three instruments differ on cost, integrity profile, supply liquidity, and counterparty considerations. Choosing between them is not just a price exercise — the choice has implications for ASRS disclosure, audit defensibility, and forward planning against the declining baseline trajectory.

This article walks through each pathway, the reasoning that favours each, and finishes with a worked example based on current reference prices.

Option 1: Surrender ACCUs

An ACCU represents one tonne of carbon dioxide equivalent (CO₂e) abated or sequestered by an approved project under the Carbon Credits (Carbon Farming Initiative) Act 2011. Projects are registered with the CER, audited periodically, and issued credits based on verified outcomes against an approved methodology.

ACCUs are the most liquid of the three Safeguard surrender instruments. The active spot market sits around $37.06 per tonne CO₂e at the reference date used in this article, with a healthy float of registered projects across method types — human-induced regeneration (HIR), savanna burning, landfill gas, soil carbon, plantation forestry, and several others. Generic-grade ACCUs trade as a fungible instrument; some buyers pay a premium for credits from specific methods or project types where integrity considerations are stronger.

ACCUs are the default surrender instrument for most covered facilities because of liquidity and the predictable supply pipeline visible in the Quarterly Carbon Market Report. The QCMR walkthrough is covered in the second article in this series — see Reading the QCMR for the supply context.

Option 2: Surrender SMCs

An SMC is issued by the CER to a Safeguard-covered facility whose reported emissions for a financial year are below its baseline. The credit represents one tonne of CO₂e of below-baseline performance. SMCs can be held, sold to another covered facility, or surrendered against a future compliance obligation.

SMC spot prices trade close to ACCU spot prices, typically within a few dollars per tonne. At the reference date, SMC spot is approximately $35.80 per tonne CO₂e — a small discount to ACCUs reflecting the narrower demand pool (only Safeguard-covered facilities are natural buyers, where ACCUs are also bought by voluntary corporates and offset intermediaries).

The case for SMC surrender over ACCU is usually one of two situations. First, when the facility's sister sites within a corporate group are net SMC generators, an intra-group transfer reduces external compliance cost. Second, when ACCU supply tightens — for example during a verification round delay — SMC supply can fill the gap. SMCs also avoid the methodology-integrity questions that occasionally affect specific ACCU project types.

The constraint with SMCs is supply scale. Total SMC issuance is bounded by the aggregate below-baseline performance of the entire covered fleet, which is structurally smaller than the ACCU pipeline. For a facility with a large compliance shortfall, SMCs alone may not be sufficient.

Option 3: Cost Containment Measure (CCM)

The CCM is a statutory price ceiling that allows compliance buyers to surrender government-issued CCM units at a fixed rate, regardless of prevailing spot prices. The rate for FY2025–26 is $82.68 per tonne CO₂e. The rate is indexed annually and the FY2026–27 rate is published by the CER each May.

The CCM exists as a backstop, not as a primary compliance pathway. It protects covered facilities from extreme price shocks if ACCU and SMC spot prices were to spike — but the ceiling is set well above current spot levels precisely so that it does not bind in normal market conditions.

Using CCM as a primary surrender choice when ACCU and SMC spot prices are well below the ceiling is economically irrational — you would be paying roughly twice the cost per tonne. The strategic interest in the CCM rate is instead as a known upper bound on compliance cost. Forward-modelling exercises can pencil in the CCM ceiling as the worst-case price, since no rational facility will pay more for ACCUs or SMCs than the CCM rate.

The decision framework

A practical workflow for selecting between the three pathways:

1. Confirm the shortfall. Calculate reported emissions less the baseline determined under the production-adjusted or site-specific methodology covered in the first article in this series. This is the surrender obligation.
2. Check intra-group SMC holdings. If sister facilities within the same corporate group hold SMCs from below-baseline performance, an intra-group transfer is typically the lowest external cost option. The transfer is administratively straightforward through the Australian National Registry of Emissions Units (ANREU).
3. Compare ACCU and SMC spot prices. For the open-market portion of the shortfall, the choice between ACCU and SMC is largely a price comparison plus liquidity check. The spread at the reference date is roughly one dollar per tonne — small enough that for most facilities, the choice falls on supply availability and counterparty considerations rather than the dollar gap.
4. Consider banking. If the facility has time before the surrender deadline and the forward curve suggests higher prices, buying earlier and banking ACCUs reduces future cost. The opposite also applies — if the facility expects below-baseline performance next year, banking current SMC holdings against future obligation may be more efficient than selling them.
5. Use CCM only at the ceiling. CCM units make economic sense only when ACCU and SMC spot prices have risen close to or above the CCM rate. At current levels, the ceiling is a planning anchor, not a purchase target.

A worked example

Consider an illustrative covered facility with a 50,000 tCO₂e shortfall against its FY2025–26 baseline. The straight cost of covering the shortfall under each pathway, using reference spot prices, is:

Indicative arithmetic using illustrative reference spot prices. Live spot prices in gridIQ are drawn from each newly published QCMR and the relevant CER releases.

The gap between the SMC and CCM totals is $2,344,000 — a material number for a single facility. The gap between SMC and ACCU on the open market is small enough to be a rounding error for liquidity decisions. The CCM ceiling matters only as the worst-case planning anchor.

Banking vs surrender now: the timing dimension

The above table treats the three pathways as a spot-price comparison at one point in time. In practice, the surrender decision interacts with timing in two ways:

• Buy-and-bank.Compliance obligations are surrendered after the financial year end. A facility expecting shortfall in FY2026–27 can buy ACCUs in late FY2025–26 if forward-curve indicators or supply context suggest prices will rise. Storage cost is zero — units sit in ANREU until surrender.
• Cumulative obligation.The declining baseline trajectory means most covered facilities face a growing shortfall over several years. Looking at FY2025–26 in isolation can mask the cumulative obligation, which is the relevant figure for setting a forward purchase strategy.

Both points argue for treating the surrender decision as a multi-year exercise rather than an annual top-up.

Where this fits in disclosure

Safeguard exposure is a material climate-related policy risk for covered facilities and their corporate parents. AASB S2 disclosure of climate-related financial information increasingly expects covered entities to quantify their compliance pathway and the assumptions underpinning it — including the surrender instruments expected to be used, the price assumptions, and the cumulative shortfall against the declining baseline trajectory.

gridIQ pairs Safeguard tracking with the ASRS Scope 2 workflow used by sustainability teams reporting under AASB S2. See the ASRS Scope 2 guide for the broader disclosure context.

Where this fits in the series

This is the third and final article in our Safeguard Mechanism series. The two earlier articles cover the methodology and the supply context:

• How Safeguard Mechanism baselines are calculated — production-adjusted and site-specific methodology, sector decline rates, and a worked baseline trajectory.
• Reading the QCMR — what the Quarterly Carbon Market Report tells you about ACCU and SMC supply, seasonal patterns, and figure-numbering gotchas.
