Free Data to Disclosure Mapping Excel Template to get ready for AASB S2 climate disclosures

Australia’s climate reporting rules are now locked in. With the AASB’s release of the final AASB S2 standard this week, mandatory climate disclosures are no longer a future concern — they’re a current reality. Reporting begins in 2025, and for most organisations, preparation needs to be underway already.

To help sustainability, finance, and risk teams get a clear head start, we’ve released our latest free resource: a Free Data to Disclosure Mapping Excel Template. It’s built to cut through the noise, simplify your path to compliance, and help your organisation feel confident about where to begin and what comes next.

Built for teams who need to move now

This resource is ideal for any organisation preparing for climate disclosure compliance in 2025. It’s particularly useful for:

• Sustainability and ESG teams that need a clear starting point and practical structure
• Finance and Risk teams supporting compliance and needing visibility into data requirements
• Executives and Boards seeking confidence that the organisation is on the right track

If you’re unsure where to begin, or if you’re already underway and want to tighten your approach, the Data to Disclosure Mapping Template will help you move faster and with more clarity.

Why this resource matters now

The final AASB S2 guidance cements a new era of mandatory climate disclosures in Australia. Based closely on the ISSB standards (IFRS S2), the framework requires organisations to disclose how they govern, manage, and assess climate-related risks and opportunities. And crucially, it requires credible, verifiable emissions and scenario data to support those disclosures.

For many companies, the challenge isn’t intent — it’s execution. Where do you even start? Who owns the right data? What systems need to be involved? This is exactly what our template helps you solve.

Our goal is to help organisations build internal clarity and confidence, especially in the early stages of planning for AASB S2 alignment. We’ve designed this template to support sustainability and ESG teams, while also being practical for finance, risk, and executive leaders who need to get across the requirements fast.

Data to Disclosure Mapping Template

🧠 Sheet 1: The disclosure summary

A high-level summary of the 4 core AASB S2 areas:

1. Governance
2. Strategy
3. Risk Management
4. Metrics & Targets

It shows:

• What each section requires
• What data you’ll need
• Where that data typically lives
• Links to the relevant AASB standards

🔗 Sheet 2: The data to disclosure guide

A practical mapping of common sustainability data types to AASB S2 disclosure requirements.

For each data type (e.g. fuel use, procurement spend, refrigerants), it shows:

• What the data is and why it matters
• Which AASB S2 section it supports
• Typical systems (e.g. SAP, EMS, travel tools)
• Typical data owners (e.g. Facilities, Finance, Procurement)

Use this to:

• Identify gaps
• Assign owners
• Prioritise systems and process changes

A structured end-to-end checklist that guides your organisation through:

✅ Setting up governance and responsibilities

✅ Collecting emissions-relevant data (fuel, electricity, waste, etc.)

✅ Performing risk and scenario analysis

✅ Setting targets and metrics

✅ Preparing disclosures in line with AASB S2

Each step includes:

• What to do
• Which team is typically responsible
