Australia’s largest industrial emitters are facing increasing pressure for accelerated decarbonisation, with a powerful A$4.6 trillion investor group publicly advocating for a significantly strengthened Safeguard Mechanism. This comes as the federal government’s 2026-27 review of the key emissions reduction policy approaches its public submission deadline of Friday, September 18, 2026.

The Clean Energy Regulator (CER) updated its public information on the Safeguard Mechanism on September 4, 2026, underscoring the ongoing nature of the scheme and its forthcoming review. The federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) initiated the review by releasing a consultation paper on August 7, 2026. The review aims to ensure the mechanism remains appropriately calibrated to achieve Australia’s emissions reduction targets of 43% below 2005 levels by 2030 and net zero by 2050.

In a significant move, the Investor Group on Climate Change (IGCC), representing institutional investors managing over A$4.6 trillion in assets, released its recommendations for the review on August 17, 2026. The IGCC’s core message is clear: the current Safeguard Mechanism settings are not driving sufficient on-site abatement and an over-reliance on offsets is worsening.

“Without effective reform, the Safeguard Mechanism will not prompt least-cost decarbonisation of Australian industries and it won’t happen fast enough to maintain competitiveness in the global economy.”

The IGCC has outlined four key objectives for the 2026-27 review:

  1. Deliver lowest-cost, most-efficient abatement: Focus on economic efficiency in emissions reduction across the Australian economy.
  2. Encourage more on-site abatement, and earlier: Shift the incentive structure to favour direct emissions reductions at facilities.
  3. Expand carbon signals: Broaden the economic reach of carbon pricing signals.
  4. Ensure proportional contribution to 2035 NDC: Align the mechanism’s outcomes with Australia’s Nationally Determined Contribution (NDC) for 2035 and the Net Zero Plan.

Key Investor Proposals for Reform

The IGCC’s submission details several concrete proposals designed to enhance the Safeguard Mechanism’s effectiveness:

  • Baseline Decline Rates: The group proposes a 5% to 7% annual decline rate for baselines from 2031 to 2035, arguing this is consistent with the 2035 emissions target range. Current modelling suggests a 7% decline rate could drive approximately 15 Mt of increased average annual abatement, with about 61% delivered on-site.
  • Differentiated Decline Rates: To ensure a more equitable distribution of the compliance burden, the IGCC recommends implementing different emissions decline rates across various industries. This would address the current imbalance where value is transferred from manufacturing to extractive industries due to differing abatement potentials.
  • ACCU Price Visibility: To improve long-term investment certainty, the IGCC suggests administering Contracts for Difference (CfDs) for Australian Carbon Credit Unit (ACCU) prices.
  • Price Corridor: Replacing the existing Cost Containment Measure with a price corridor (including a floor) would allow prices to rise predictably, providing a stronger incentive for abatement.
  • Financial Support: The investors advocate for an enduring form of financial support to accelerate investment in on-site decarbonisation projects.
  • Expanded Coverage: The IGCC recommends progressively lowering the facility emissions threshold, starting with 75,000 tonnes of CO2-equivalent by 2031, to expand the scheme’s coverage.

Industry Impact and Future Outlook

The Safeguard Mechanism applies to facilities emitting more than 100,000 tonnes of carbon dioxide equivalent (tCO2-e) per year, encompassing sectors such as mining, oil and gas production, manufacturing, transport, and waste. The review’s outcomes will directly impact how these major industrial players plan their decarbonisation strategies and allocate capital over the coming decades.

While Climate Change and Energy Minister Chris Bowen stated in August 2026 that the review is not intended to fundamentally redesign the mechanism, it will examine how the existing framework can continue to deliver effective emissions outcomes beyond 2030, with a particular emphasis on domestic abatement and industrial decarbonisation.

For businesses navigating Australia’s evolving energy policy landscape, understanding these proposed changes is critical. The push for stronger on-site abatement and more robust carbon pricing signals could necessitate significant investment in new technologies and operational efficiencies. The review process, set to conclude in early 2027 with policy positions and draft rule amendments, will be a defining moment for Australia’s industrial transition to net zero.

Maintaining a focus on emissions reduction while managing energy costs is a complex challenge for Australian businesses.

The outcomes of this Safeguard Mechanism review will play a pivotal role in shaping the commercial energy environment for years to come.

Comparison of Current vs. Proposed Safeguard Mechanism Settings
