Seven Frameworks, One Footprint
AASB S2. SECR. CDP. ISSB. GRI. SBTi. TCFD. Same emissions data, seven different formats. The disclosure maze is real.
At a Glance
▸ A business operating in AU + UK faces 6-7 disclosure frameworks simultaneously
▸ The majority of data requirements overlap - but the divergences are where complexity lives
▸ Materiality definitions, reporting boundaries, and scenario requirements all diverge
▸ Solution: collect data once, output to many frameworks from a single source of truth
A sustainability manager at a mid-market Australian company with UK operations sits down to prepare annual disclosures. The emissions data is the same. The underlying methodology is the same. But the output requirements are completely different depending on which framework, regulator, or stakeholder is asking.
The data doesn't change. The formatting does. Formatting is consuming 60-70% of the disclosure effort for cross-jurisdictional businesses.
The Framework Map
| Framework | Where | Mandatory? | Scope | Key Difference |
|---|---|---|---|---|
| AASB S2 | Australia | Yes (2025+) | S1, 2, 3 | Climate-financial integration |
| SECR | UK | Yes | S1, 2 | Energy + intensity metrics |
| CDP | Global | Voluntary\* | S1, 2, 3 | Investor/supply chain driven |
| ISSB S2 | Global | Varies | S1, 2, 3 | Global baseline standard |
| GRI | Global | Voluntary | All ESG | Double materiality |
| SBTi | Global | Voluntary | S1, 2, 3 | Target validation |
\CDP is voluntary in theory. In practice, if your major customers or investors request it, it's mandatory by default.*
Where They Diverge
A significant share of data requirements overlap across frameworks. The divergences are where complexity and cost live.
| Dimension | ISSB / AASB S2 | GRI | CDP |
|---|---|---|---|
| Materiality | Financial materiality | Double materiality (impact + financial) | Blended |
| Boundary | Financial reporting entity | Operational impact | Operational control |
| Scenario Analysis | Required (qualitative initially, quantitative by year 4) | Not required | Qualitative accepted |
| Assurance | Moving to mandatory | Recommended | Scored, not assured |
| Same topic. Different definitions. A single topic can be material under one framework and immaterial under another. A joint venture in-scope under one and out-of-scope under another. |
The Real Cost
For mid-market businesses, the cost isn't just financial. Every hour reformatting disclosure for a different framework is an hour not spent on emissions reduction, supply chain engagement, or operational improvement.
ISSB is creating convergence. AASB S2 is the Australian adoption. UK SRS will follow. But convergence takes years. In the meantime, businesses report across multiple frameworks simultaneously.
The solution isn't picking one framework. It's building data infrastructure that collects once and outputs to many. One source of truth. Multiple disclosure formats.
One platform. Every framework. No re-keying.
✔ Multi-framework disclosure from a single data input - AASB S2, SECR, CDP, ISSB, GRI
✔ Audit-ready outputs pre-formatted for each standard's specific requirements
✔ End-to-end integrated platform: carbon accounting + risk + scenario analysis + disclosure
✔ All outputs in Excel. Your data, your way. No vendor lock-in.
