If your Queensland business works in mining services, logistics, transport, construction, or any industry that contracts with mid-to-large companies, AASB S2 Group 2 reporting is coming your way. Fast. You may not be the one filing the report — but your clients are, and they will be asking you for carbon data, emissions disclosures, and climate risk information as part of their supply chain. If you can't provide it, you risk losing tenders and contracts.

What Is AASB S2?

AASB S2 is Australia's mandatory climate disclosure standard, adopted from the global IFRS S2 framework developed by the International Sustainability Standards Board (ISSB). It is administered under Chapter 2M of the Corporations Act 2001, overseen by ASIC.

In plain English: if your business (or your client) is above a certain size, they are now legally required to measure and report their climate-related risks, opportunities, and greenhouse gas emissions as part of their annual report. This isn't voluntary. It isn't optional. And it isn't going away.

The reporting rollout is happening in three waves — Group 1, 2, and 3 — based on company size.

Who Is a Group 2 Entity?

Group 2 entities are mid-to-large Australian companies that meet at least two of these three criteria on a consolidated group basis:

Threshold Group 2 Level
Consolidated revenue $200 million or more
Consolidated gross assets $500 million or more
Number of employees 250 or more

You are also in Group 2 if your company is a controlling corporation required to report under the NGER Act (but not already in Group 1), or an asset owner such as a superannuation fund or managed investment scheme with $5 billion or more in assets under management.

Think: mid-market mining services companies, regional logistics operators with large fleets, food processing firms, construction contractors on major projects, and resource sector support businesses across Central and North Queensland.

When Does Group 2 Reporting Start?

Group 2 reporting begins for financial years starting on or after 1 July 2026. That means if your financial year runs July–June, your first reporting year is FY2026–27, with your first report due in late 2027.

Reporting Group Reporting Starts Revenue Threshold
Group 1 1 January 2025 $500M+
Group 2 1 July 2026 $200M+
Group 3 1 July 2027 $50M+

⏰ July 2026 is less than four months away. Data collection for Scope 1 and 2 emissions needs to be live from day one of the reporting period — which means systems and processes need to be in place now, not after July.

What Does AASB S2 Require Group 2 Entities to Disclose?

AASB S2 is built on four disclosure pillars, all mandatory for Group 2 from Year 1:

1. Governance

Disclose how your board and management oversee climate-related risks and opportunities. This includes who is responsible, how often it is reviewed, and whether climate risk is linked to remuneration or decision-making. ASIC expects this to sit at board level, not buried in an environmental team.

2. Strategy

Identify transition risks — policy changes, new carbon pricing, market shifts away from fossil fuels — and physical risks such as flooding, extreme heat, and cyclones that could affect your cash flows. You must conduct climate scenario analysis using at least two temperature pathways: a 1.5°C scenario and a 2.5°C+ scenario, referencing global frameworks.

3. Risk Management

Explain how your business identifies, assesses, and monitors climate-related risks and how this connects to your broader enterprise risk management process. ASIC is clear: climate risk should not be treated as a standalone ESG exercise; it belongs in the same framework as financial and operational risk.

4. Metrics & Targets — The Biggest Challenge

This is where most Queensland businesses will feel the pressure. The key emissions requirements are:

  • Scope 1 & 2 emissions: Mandatory from Year 1 (July 2026). Scope 1 covers your direct emissions — diesel, gas, process emissions. Scope 2 covers electricity purchased from the grid. Both must be reported location-based using Australian grid emissions factors.
  • Scope 3 emissions: Mandatory from Year 2 (FY2027–28). This covers all indirect emissions in your value chain — your suppliers, contractors, transport, purchased goods, and business travel. A one-year grace period applies, but supplier data collection should start in Year 1 given the complexity of preparation.
  • Climate-related targets: Disclose any emissions reduction targets set, the methodology used, and your progress against them.
  • Other metrics: Internal carbon price (if used in decisions) and climate-related capital expenditure.

What About Assurance?

External assurance is mandatory from your first reporting year — this isn't self-certified. Assurance is conducted under AUASB standard ASSA 5000 and is phased as follows:

  • Year 1: Limited assurance over Scope 1 & 2 emissions, governance disclosures, and selected strategy content.
  • Years 2–3: Limited assurance over all AASB S2 disclosures.
  • From 1 July 2030: Reasonable (full) assurance over all climate-related financial disclosures.

This means your emissions data needs to be credible, documented, and audit-ready from day one. A spreadsheet estimate won't cut it.

Why This Matters for Regional Queensland Businesses in Mining Services & Logistics

Here's the uncomfortable truth: you may not be in Group 2 yourself, but your clients almost certainly are in Group 1 or 2. Glencore, BHP, BMA, Anglo, QCoal, Cleanaway, Toll, Aurizon, Bechtel, and dozens of mid-market operators across the Bowen Basin, Surat Basin, and Gladstone industrial corridor — or Brisbane-headquartered companies with regional Queensland operations — will all be required to report Scope 3 emissions as part of their AASB S2 disclosures from Year 2.

Scope 3 is their supply chain. That's you.

When your client asks "what's your carbon footprint?" in a tender next year, they're not being curious. They're filling in a mandatory climate disclosure. If you can't answer:

  • You may be dropped from preferred supplier lists.
  • Your client may use generic emission factors, which often overestimate your footprint and make you look worse.
  • You lose the ability to differentiate on sustainability credentials in contract bids.
  • You have no baseline to set targets against — which is increasingly a tender requirement itself.

For mining services contractors in Gladstone, Rockhampton, Mackay, and Townsville, this is not a future issue. Procurement teams at major resource companies are already building Scope 3 data collection programs. Some are already asking contractors for emissions data in tender documentation. Whether you're based in Brisbane, Gladstone, Rockhampton, or Mackay, the questions your clients are about to ask you are the same — and the window to prepare is closing.

For regional logistics and transport businesses, fleet emissions are almost entirely Scope 1 for you but Scope 3 for your clients. As freight companies face growing pressure from decarbonisation strategies, knowing your exact fleet emissions per tonne-kilometre is becoming a commercial requirement, not just a compliance exercise.

💡 You don't need to file an AASB S2 report to be affected by it. If you supply to businesses that do, your carbon data is part of their mandatory disclosure — whether you're ready or not.

What Should You Do Right Now?

You don't need to file a report. But you do need to be ready to support the ones who do. Here's a simple action plan for regional Queensland SMEs:

  1. Know your own emissions baseline. Get a carbon footprint of your business — Scope 1 (fuel, gas) and Scope 2 (electricity) at minimum. This is the number your clients will ask for first.
  2. Understand what Scope 3 means for your industry. If you're in mining services, transport, or supply chain work, start mapping which categories of Scope 3 apply to you — purchased goods, downstream transport, waste, business travel.
  3. Have your numbers in a shareable format. A simple, credible, one-page emissions summary attached to your tender is already a differentiator in regional Queensland. Our Tender-Ready Carbon Snapshot™ is built exactly for this.
  4. Don't wait for your clients to ask. By the time they send you a supplier questionnaire, you'll have two weeks to respond. Build the data now.
  5. Talk to someone who understands regional operations. City-based consultants will charge you for complexity you don't need. At Aethiro, we work onsite, we know regional Queensland industry, and we explain everything in plain English.

Frequently Asked Questions

You are not required to file an AASB S2 report yourself unless you meet the Group 2 or Group 3 size thresholds. However, your clients who are Group 1 or Group 2 entities must report their Scope 3 emissions, which includes emissions from their supply chain — that means you. When they ask for your carbon data in a tender or supplier questionnaire, it's a mandatory disclosure requirement for them, not just a preference. If you can't provide it, they may use generic emission factors or remove you from their preferred supplier list.
Scope 3 emissions become mandatory for Group 2 entities from Year 2 of their reporting — which is FY2027–28 for those starting in July 2026. However, ASIC expects Scope 3 data collection to begin in Year 1, as building supplier data programs takes time. If you're a supplier to Group 2 entities, expect to be asked for your emissions data from late 2026 or early 2027 at the latest.
Limited assurance means an independent auditor has reviewed your climate disclosures and found no evidence that they are materially misstated — it is less rigorous than a full audit (reasonable assurance) but significantly more demanding than self-certification. For Group 2 entities, limited assurance over Scope 1 and 2 emissions and governance disclosures is required from Year 1. This means your emissions data must be credible, documented, and traceable from the very first reporting period.
