Safeguard Mechanism: Australia's Industrial Emissions Reduction Scheme
The Safeguard Mechanism is Australia's key policy for reducing emissions from the nation's largest industrial facilities. Reformed in 2023, it sets declining emissions baselines for facilities emitting more than 100,000 tonnes of CO2-e annually, driving Australia's largest emitters toward net zero by 2050.
Effective from: 1 July 2023 (Reformed)
Overview
The Safeguard Mechanism was introduced in 2016 under the National Greenhouse and Energy Reporting Act 2007 (NGER Act) and significantly reformed in 2023. It applies to Australia's highest-emitting facilities – approximately 215 facilities responsible for around 28% of national emissions. Under the reformed mechanism, facilities must keep their net emissions at or below a baseline that declines by 4.9% annually, aligned with Australia's commitment to reduce emissions by 43% below 2005 levels by 2030 and achieve net zero by 2050. Facilities can meet their obligations through actual emissions reductions, purchasing Australian Carbon Credit Units (ACCUs), or acquiring Safeguard Mechanism Credits (SMCs) from facilities that beat their baselines.
Key Points
- Applies to facilities emitting 100,000+ tonnes CO2-e per year
- Baselines decline 4.9% annually to 2030
- Covers approximately 215 facilities (28% of national emissions)
- Compliance through reduction, ACCUs, or SMCs
- New facilities subject to international best practice baselines
- Administered by the Clean Energy Regulator
Disclosure Pillars
Key areas of disclosure required under Safeguard Mechanism
Emissions Baselines
Each covered facility receives an emissions baseline that declines 4.9% annually, representing the maximum net emissions allowed.
- Production-adjusted baselines reflect output changes
- Site-specific baselines for unique circumstances
- Industry average baselines where applicable
- New facilities get best practice baselines
Compliance Options
Facilities have multiple pathways to meet their baseline obligations, providing flexibility in how they achieve compliance.
- Actual emissions reductions at facility
- Purchase Australian Carbon Credit Units (ACCUs)
- Acquire Safeguard Mechanism Credits (SMCs)
- Combination of reduction and credits
Safeguard Mechanism Credits (SMCs)
Facilities that reduce emissions below their baseline can earn tradeable credits, creating incentives for early action.
- One SMC equals one tonne CO2-e below baseline
- Tradeable between Safeguard facilities
- Can be banked for future compliance
- Creates market-based incentive for overperformance
Reporting & Verification
Facilities must report emissions annually under NGER and demonstrate compliance with their Safeguard obligations.
- Annual NGER reporting of emissions
- Safeguard compliance reporting
- Third-party verification for large emitters
- Clean Energy Regulator oversight
Implementation Timeline
Key dates and milestones for Safeguard Mechanism compliance
Original Mechanism Commenced
The Safeguard Mechanism began operation with static baselines, applying to facilities above the emissions threshold.
Reform Legislation Passed
Parliament passed the Safeguard Mechanism (Crediting) Amendment Act 2023, introducing declining baselines and the crediting mechanism.
Reformed Mechanism Commenced
New declining baselines took effect, with 4.9% annual reduction trajectory aligned with Australia's 2030 target.
First Full Compliance Year
First complete financial year under the reformed mechanism with declining baselines and SMC trading.
43% Reduction Target
Australia's legislated target to reduce emissions 43% below 2005 levels, supported by Safeguard Mechanism reductions.
Net Zero Target
Long-term goal for covered facilities to achieve net zero emissions, with pathway established through declining baselines.
Who Must Report
The Safeguard Mechanism applies to facilities that emit 100,000 tonnes or more of covered emissions (Scope 1) in a financial year. Approximately 215 facilities across Australia are currently covered.
Entities Included
- Large industrial manufacturing facilities
- Mining operations (coal, iron ore, gold, other minerals)
- Oil and gas extraction and processing
- LNG production facilities
- Aluminium smelters
- Steel manufacturing
- Cement production
- Large transport hubs and logistics
- Waste management facilities above threshold
Key Benefits
Why organisations choose to comply with Safeguard Mechanism
Regulatory Certainty
Clear, predictable declining baselines provide long-term certainty for investment and operational planning through to 2050.
Flexibility
Multiple compliance pathways allow facilities to choose the most cost-effective approach based on their circumstances and abatement opportunities.
Early Mover Advantage
Facilities that reduce emissions faster than required can earn and sell SMCs, creating revenue from environmental performance.
International Competitiveness
The mechanism includes provisions to protect trade-exposed industries while driving emissions reductions aligned with global trading partner expectations.
Carbon Market Participation
Integration with the ACCU market and new SMC market provides opportunities for carbon market engagement and price discovery.
Alignment with Net Zero
Declining baselines create a clear pathway to net zero by 2050, aligned with Australia's international commitments.

Frequently Asked Questions
Common questions about Safeguard Mechanism compliance
Key Terminology
Baseline
The maximum amount of net covered emissions a facility can emit before needing to surrender credits.
ACCU
Australian Carbon Credit Unit - a tradeable carbon credit representing one tonne of CO2-e avoided or removed.
SMC
Safeguard Mechanism Credit - issued when a facility's emissions are below its baseline, tradeable with other covered facilities.
Covered Emissions
Scope 1 emissions from industrial processes, fuel combustion, and fugitive sources at a facility.
Production-Adjusted Baseline
A baseline that adjusts for changes in facility production, allowing increased production without immediate baseline breach.
EITE
Emissions-Intensive Trade-Exposed - industries that face international competition and have high emissions intensity.
