As mandatory climate reporting under AASB S2 becomes enforceable for an increasing number of Australian organisations, the market for carbon accounting software is growing rapidly. There are now dozens of platforms available, ranging from global enterprise tools to local Australian-built solutions. Choosing the right one is a significant decision that will affect your compliance quality, audit costs, and reporting efficiency for years to come.

This guide walks you through the key criteria to evaluate when selecting a carbon accounting platform for ASRS compliance.

1. Built for Australian Standards (Not Just Retrofitted)

The most important question to ask any carbon accounting software vendor is: was this platform built for AASB S2 and ASRS, or is it an international product adapted for the Australian market?

Australian carbon accounting has specific requirements that differ from international frameworks:

• The use of Australian National Greenhouse Accounts (NGA) emission factors for electricity and energy
• Alignment with the specific disclosure requirements of AASB S2 (which has some differences from IFRS S2 in its Australian implementation)
• Integration with Australian regulatory reporting obligations

A platform built from scratch for the Australian market will have these features natively. An international platform adapted for Australia may require workarounds or manual adjustments that increase your audit risk.

2. Scope 3 Coverage and Supplier Integration

Scope 3 is where most organisations’ emissions are — and where the most significant data challenges exist. Evaluate any platform on how it handles Scope 3 specifically:

• Does it support all 15 Scope 3 categories defined by the GHG Protocol?
• How does it collect and integrate supplier data?
• Does it apply credible spend-based and activity-based methodologies where primary data isn’t available?

Look for platforms that offer automated supplier data collection — portals or integrations that allow your supply chain to submit their own data, rather than requiring you to manually chase information via surveys and emails.

3. Audit-Ready Evidence Chains

Under AASB S2, climate disclosures are subject to external assurance — initially limited assurance, with a pathway to reasonable assurance. This means every figure in your disclosure needs to be traceable back to source data. Ask vendors:

• Can an auditor drill down from the final emissions number to the underlying data source?
• Is that evidence chain documented, timestamped, and tamper-evident?

Platforms that simply produce a summary output without full data lineage will create significant problems at audit time.

4. Automation and Integration with Your Existing Systems

The real productivity gain from carbon accounting software comes from automation — eliminating the manual data entry and spreadsheet manipulation that makes carbon reporting so time-consuming. Evaluate platforms on their integration capabilities:

• Can they connect directly to your accounting software, energy management systems, fleet management tools, and procurement platforms?
• Do they offer direct API integrations or pre-built connectors to the systems you actually use?

Manual data upload via CSV is a baseline requirement, but the best platforms go significantly further.

5. Scalability Across Sites and Business Units

If your organisation operates across multiple sites, business units, or legal entities, you need a platform that can handle multi-entity carbon accounting with appropriate aggregation and reporting at each level. Some platforms are designed primarily for single-entity reporting and struggle with complex organisational structures.

6. Reporting and Disclosure Output

The platform should be able to produce disclosure-ready outputs aligned with AASB S2’s specific reporting structure — not just a general ESG summary. Ask to see a sample report and verify that it maps to the governance, strategy, risk management, and metrics & targets pillars required by AASB S2. The best platforms produce board-ready and regulator-ready outputs with minimal manual formatting effort.

7. Pricing Transparency and Total Cost of Ownership

Carbon accounting platform pricing varies widely — from subscription-based SaaS models to consulting-led implementation fees. Ensure you understand the total cost of ownership, including:

• Implementation fees
• Annual licence costs
• Support charges
• The cost of any customisation or additional integrations you need

Compare this against the cost of alternative approaches (spreadsheets, consultants) to understand the genuine return on investment.

Questions to Ask in a Demo

• How does the platform specifically align with AASB S2’s disclosure requirements?
• Can you show me the audit trail from a final emission number back to the source data?
• How does the platform handle Scope 3 supplier data collection?
• What Australian emission factors does the platform use, and how are they updated?
• What does a typical implementation timeline look like for an organisation of our size?
• What level of assurance have your clients achieved with their reports?
