Introduction
Carbon pricing in Australia has shifted from background noise to a line item that can move earnings. With the reformed Safeguard Mechanism now live and Australian Carbon Credit Unit prices expected to rise, the window for low‑cost action is narrowing. This guide sets out what changes by 2030, how the numbers flow through budgets, and the practical moves that protect margins while positioning for growth.
The carbon price trajectory to 2030 in plain numbers
Where prices sit today
- Australian Carbon Credit Units (ACCUs) have traded around 40–41 per tonne in 2024.
- Government cost containment ceiling: 75 per tonne in 2023–24, indexed by CPI plus 2 percent annually.
What credible modelling says next
- Carbon Market Institute survey: almost two‑thirds of businesses expect ACCUs above 90 by 2035.
- EY Net Zero Centre: prices could approach the cost containment ceiling before 2035.
- RepuTex scenarios show faster rises if baselines tighten to 7–10 percent annually later this decade.
Why this matters: A move from 40 to 80–90 per tonne doubles compliance outlays. For facilities with thin margins or inflexible processes, delayed planning can translate into rushed purchasing at peak prices.

How the Safeguard Mechanism works in practice
Coverage and scope
- About 215 facilities, responsible for roughly 28 percent of national emissions, with a threshold of 100,000 tCO2‑e per year.
Declining baselines at 4.9 percent annually
- Baselines now decline each year to 2030, removing previous headroom.
- Production‑adjusted baselines recognise output changes but still require intensity improvement over time.
Credits, timing and cash flow
- Over‑baseline emissions must be covered by ACCUs or Safeguard Mechanism Credits (SMCs).
- Facilities that beat their baseline can generate SMCs for sale to covered peers.
- Compliance surrender deadline: 31 August each year for the prior financial year.
- Government ACCU cost containment: 75 per tonne in 2023–24, indexed annually; market prices may converge toward this level over time.
Market design and price signals
- ACCUs are sourced from projects across land, industrial and waste sectors.
- SMCs are facility‑generated and may trade at a premium depending on market preferences and audit confidence.
- Expect seasonal price spikes as deadlines approach due to limited liquidity.
What it means for budgets and compliance costs
System‑wide spend
- Annual compliance costs across covered facilities are estimated at about 1.7 billion, summing to roughly 11.7 billion through 2030.
Translating prices to your P&L
- Every 10 per tonne change in ACCU price equals 1 million per 100,000 tCO2‑e exposure.
- Baseline decline compounds exposure even if absolute emissions are flat.
- Banking can smooth costs, but rising baselines mean stockpiles deplete faster without abatement.
Procurement tactics for volatile markets
- Ladder purchases across the year to avoid deadline spikes.
- Set guardrails with minimum and maximum buy bands tied to price triggers.
- Maintain a split between ACCUs and SMCs based on availability, audit posture and counterparty preferences.
Industrial decarbonisation strategies that move the dial
Renewable energy procurement and PPAs
- Long‑dated PPAs can lock in price certainty and reduce Scope 2 emissions.
- Consider shaped products and firming solutions to manage intermittency, particularly for 24/7 processes like smelting.
Mining fleet electrification
- Diesel combustion can be around one‑fifth of mining emissions; electrified haulage and in‑pit crushing offer sizeable cuts.
- Remote sites may require new substations, microgrids and storage; staged rollouts reduce disruption.
Hydrogen direct reduction for steel
- For integrated steel, hydrogen‑based direct reduction plus electric arc furnaces is the key technology pathway.
- Requires access to low‑cost renewable electricity and hydrogen; front‑end studies de‑risk later capex.
Carbon capture and storage (CCS)
- Most relevant for process emissions and gas processing; assess local geology, transport options and long‑term liability frameworks.
Process electrification and efficiency
- Heat pumps, electric boilers and high‑efficiency motors tackle medium‑ and low‑temperature heat loads now.
- Waste heat recovery and advanced controls typically pay back faster than greenfield technology shifts.

Sector snapshots to 2030
Mining
- Key sources: diesel haulage, electricity for processing, coal mine methane.
- Electrification and renewable microgrids cut Scope 1 and 2; methane management requires measurement upgrades to target real leaks.
Manufacturing
- Steel: hydrogen‑DRI pilots position assets for the 2030s; interim steps include scrap‑based EAF capacity where feasible.
- Aluminium: grid decarbonisation and PPAs deliver outsized gains; cell technology and energy efficiency improve intensity.
- Chemicals and fertilisers: process redesign and electrification, with CCS considered for concentrated streams.
Oil and gas
- Focus areas: compressors, flaring, venting, and offshore power. CCS and electrification of platforms are emerging.
Power generation
- Covered by sectoral baselines aligned to the grid transition. Industrial buyers should align PPA strategies with expected grid emissions intensity paths.

Supply chain and Scope 3 moves
Why Scope 3 shapes demand and pricing
- Customers are building supplier scorecards that preference low‑carbon inputs.
- Early suppliers of low‑carbon commodities can unlock long‑term offtakes and price premiums where available.
Practical steps
- Build emissions clauses into procurement and logistics contracts.
- Request primary data from strategic suppliers; default to quality secondary data where necessary.
- Align product‑level footprints with marketing and sales to avoid inconsistent claims.
Governance and planning actions for the next 12 months
- Set an internal carbon price that reflects expected 2030 ACCU levels and use it in capital allocation.
- Establish a credit procurement policy with price bands, counterparties and risk limits.
- Run a baseline‑to‑budget bridge showing how the 4.9 percent decline flows through to 2030.
- Prioritise no‑regrets abatement: energy efficiency, metering, renewable PPAs for load pockets, and methane measurement.
- Commission pre‑FEED or feasibility studies for larger shifts such as fleet electrification, CCS or hydrogen‑DRI where relevant.
- Stand up a monthly carbon close: reconcile activity data, update factors, and track forecast surrender needs and cost.
- Lock in independent assurance capacity and test controls ahead of the deadline.
Risks to watch, opportunities to capture
- Policy tightening risk: higher baseline decline rates would lift credit demand and prices; scenario test 7–10 percent declines.
- Liquidity risk: concentrated buying ahead of 31 August can spike prices; stagger purchases.
- Supply risk: land‑based ACCU supply can vary with seasons and approvals; diversify sources and evaluate SMC availability.
- Reputation and access to capital: transparent, audit‑ready reporting supports stakeholder confidence and borrowing costs.
- Market positioning: outperforming baselines can create SMC revenues and preferred customer status for low‑carbon products.
Quick FAQ
Q: ACCUs vs SMCs — which should be prioritised?
A: Both have roles. ACCUs offer broader supply; SMCs are generated within the scheme and may be valued for compliance clarity. Maintain flexibility and price discipline.
Q: Can international credits be used?
A: The government has indicated potential for high‑quality international units with strict limits. Timing and quantity remain uncertain, so plan for domestic credits first.
Q: Does banking credits remove future exposure?
A: Banking helps smooth timing, but declining baselines increase needs over time. Pair banking with real abatement to avoid being outpaced by the decline.
Conclusion
By 2030, the Safeguard Mechanism will reward organisations that treat carbon like cash: measured daily, forecast monthly, governed tightly. Prices trending toward 80–90 per tonne and baselines falling at 4.9 percent a year reshape capital planning and procurement today. The organisations that integrate a reliable carbon accounting spine, stage credible abatement, and buy credits with discipline will find more room to move when markets tighten.
