AASB S2
Implementation for Group 2 & Group 3 Companies
A systemised, DIY solution built from Tier 1 work.
Run it internally. Own the system. Avoid Big 4 dependency.
BRINGS CLIMATE TO THE BOARDROOM
AASB S2 has moved climate from sustainability reporting into governance, enterprise risk, strategy and financial decision-making.
This system is designed for CFO-led teams who need this done properly, without overspending on consultants or locking the business into external dependency.
THE PROBLEM CFOs ARE ACTUALLY DEALING WITH
AASB S2 is now mandatory for Group 2 and Group 3 Australian Companies.
What that really mean is:
- boards expect documented governance and judgement.
- auditors expect traceable evidence.
- finance teams are accountable for consistency and defensibility.
- sustainability teams are no longer operating in isolation.
Most companies quickly run into the same constraints:
- Big 4 and large consultancies quote $300k or more.
- platforms focus on visualisation, not decision structure.
- internal teams do not have time to build systems from scratch.
- CFOs end up personally carrying the risk.
This is not a capability problem.It is a system problem.
The Cheat Code
We’ve developed you a systemised AASB S2 implementation template suite that allows you to integrate climate risk, opportunity, scenario analysis and strategy into your existing business processes.
The system is available as a full end-to-end suite, or as individual modules that you can deploy where you need them most.
The suite covers:
-
- governance and accountability
- basis of preparation and judgement
- risk and opportunity assessment
- scenario analysis and financial integration
- value chain and Scope 3 screening
- strategy and target setting
- disclosure control and assurance readiness
It is not software.
It is not consulting.
It is implementation infrastructure.
WHY THIS SYSTEM WORKS
This system was:
-
- built from Tier 1 delivery experience.
- reviewed and assured in Big 4 environments.
- re-engineered specifically for Group 2 and Group 3 companies.
- designed to be practical, proportionate and reusable.
You own the system.
You reuse it year on year.
You keep the money in-house to actually execute your climate strategy.
Every module:
-
- enforces sequencing so teams do not skip steps.
- makes assumptions and judgement explicit.
- links disclosures back to underlying evidence.
- supports board and audit scrutiny.
WHO THIS IS FOR
This solution is designed for you:
Group 2 and Group 3 Australian companies
In scope for AASB S2 and facing near-term reporting expectations.
CFOs accountable for risk and assurance
Who need defensible outputs without creating consultant dependency.
Lean sustainability, finance and risk teams
Who need structure, not more software.
Asset-heavy and emissions-exposed sectors
Including mining, energy, manufacturing, infrastructure, logistics and processing.
If you want someone else to run this for you, this is not the right solution.
If you want a system your team can own, it is.
HOW COMPANIES USE IT
Companies typically:
- Purchase the full suite for end-to-end coverage, or select individual modules to fill specific gaps.
- Assign internal owners across finance, risk and sustainability.
- Follow the sequencing set out in the system.
- Populate templates using their own data and judgement.
- Produce board-ready and audit-ready outputs.
- Reuse the system in subsequent reporting periods.
For teams that want additional confidence while executing internally, an optional climate support package is available.
0 CLIMATE SUPPORT PACKAGE (OPTIONAL)
This includes:
- monthly check-ins to maintain momentum and accountability
- on-call guidance to sense-check decisions and documentation
- access to targeted training and assessments as teams progress
Execution remains internal.
The support is there to keep teams moving, not to replace them.
WHY THIS EXISTS
This system exists because most mid-market companies:
- cannot justify $300k plus in external consulting.
- don’t want another software platform to add to the list.
- do not want to rebuild the same work every year.
- still need outputs that auditors and boards accept.
- want internal capability, not long-term dependency.
There is a gap between Big 4 consulting and starting from a blank page. This system fills that gap.
WHAT THIS IS NOT
This is not:
-
- a reporting dashboard.
- a compliance shortcut.
- a consulting engagement disguised as templates.
- a stripped-down Group 1 solution.
It is the same underlying system used in Tier 1 companies, adapted for companies that need control over cost and capability.

A systemised, DIY AASB S2 implementation suite built from Tier 1 work, designed specifically for Group 2 and Group 3 companies to run internally, without Big 4 consulting.
PROCUREMENT JUSTIFICATION
This purchase replaces traditional external consulting spend with an internally owned AASB S2 implementation system.
Rather than paying for repeated advisory engagements, the company acquires a structured, reusable framework that can be run internally across reporting periods.
Commercial Rationale
Traditional AASB S2 advisory delivered by large consulting firms typically:
- costs in excess of $300,000
- requires significant internal time in addition to consulting fees
- creates dependency on external advisers
- must be repurchased or substantially repeated each reporting cycle
The systemised template suite:
- represents a one-off investment
- is reusable year on year
- removes the need for repeat consulting engagements
- enables delivery at a fraction of the cost
This approach materially reduces long-term cost while maintaining quality and defensibility.
Capability and Knowledge Retention
Under a consulting-led model:
- knowledge, methodology and decision logic sit with the adviser
- internal teams remain dependent on external expertise
- capability does not materially improve over time
Under this systemised approach:
- methodology and decision logic are owned internally
- finance, risk and sustainability teams build capability as they execute
- knowledge is retained within the company
This supports stronger governance and more efficient future reporting cycles.
Risk and Assurance Considerations
The system has been:
- built from Tier 1 delivery experience
- reviewed in Big 4 assurance environments
- structured to align with audit expectations
It:
- documents assumptions, boundaries and judgements
- links disclosures to underlying evidence
- supports consistency across governance, risk, strategy and reporting
This provides audit confidence without requiring external consultants to run the process.
Fit with Internal Delivery Model
The system is designed to:
- integrate into existing finance, risk and sustainability processes
- be executed by internal teams
- support staged implementation where required
Optional light-touch support is available, but delivery and accountability remain internal.
Value for Money
This purchase:
- replaces a high-cost, consultant-led delivery model
- reduces repeat expenditure in future years
- improves internal capability and control
- supports audit and board scrutiny
It represents a lower-risk, higher-value alternative to traditional consulting for Group 2 and Group 3 companies.
Summary Statement
This investment enables the company to:
- meet AASB S2 requirements using an internally owned system
- avoid ongoing dependency on external consultants
- maintain audit confidence and governance integrity
- retain more capital to execute the company’s climate strategy
FREQUENTLY ASKED QUESTIONS
Is this a consulting engagement?
No.
This is a systemised AASB S2 implementation template suite designed to be run internally by your team.
We provide the structure, templates and guidance.
Your team executes the work.
Optional light-touch support is available, but ownership and delivery remain internal.
Is this a software platform or reporting tool?
No.
This is not a dashboard, data platform or reporting system.
It is implementation infrastructure that sits around your existing finance, risk and sustainability processes and tools.
Who is this designed for?
This system is designed specifically for:
- Group 2 and Group 3 Australian companies
- CFO-led teams accountable for governance, risk and assurance
- Lean sustainability and risk teams that need structure
- Asset-heavy and emissions-exposed businesses
It is not designed for Group 1 entities or companies looking to outsource delivery.
Can we purchase individual modules or do we need the full suite?
Both options are available.
You can purchase the full end-to-end suite or select individual modules to address specific gaps such as scenario analysis, governance or disclosure readiness.
Most companies choose the full suite to avoid rework and sequencing issues, but modular purchase is available where appropriate.
Will auditors accept outputs produced using this system?
Yes.
The system has been built from Tier 1 delivery experience and reviewed in Big 4 assurance environments.
It is structured to:
- make assumptions and judgement explicit
- link disclosures to underlying evidence
- support traceability and consistency
Auditors assess the quality of governance, documentation and evidence, not who produced it.
How much internal effort is required?
This is not a “set and forget” solution.
You will need to invest internal time across finance, risk and sustainability.
The system replaces consultants, not effort.
Most companies find the structured templates significantly reduce time compared to building from scratch or responding to ad-hoc consultant requests.
What internal capability do we need?
You do not need climate specialists.
You need:
- finance and risk leads who understand the business
- access to operational and asset data
- the ability to make and document judgement
The system is designed to guide teams step-by-step.
How long does implementation typically take?
Most companies work through the system over 6-9months, depending on scope, internal availability and which modules are purchased.
Because it is modular and reusable, work can be staged over time if required.
What is the optional climate support package?
The climate support package is a light-touch support option for teams who want guidance without handing over delivery.
It can include:
- monthly check-ins
- on-call guidance for sense-checking decisions
- access to targeted training and assessments
Execution remains internal at all times.
How is this different from using a platform?
Platforms help you visualise data.
They do not:
- establish governance
- document judgement
- define boundaries and assumptions
- control disclosures
- prepare audit-ready narratives
This system focuses on decision structure and documentation, which platforms do not provide.
How is this different from Big 4 consulting?
Simply, we don’t rip you off.
Big 4 consulting typically:
- costs $300k or more
- runs the work for you
- retains IP and knowledge externally
- requires repeat spend every year
This system:
- is owned by your company
- is reusable year on year
- builds internal capability
- costs a fraction of traditional consulting
Is this just a compliance solution?
No.
While it supports AASB S2 requirements, the system is designed to integrate climate into governance, risk and strategy, not just produce a report.
Many companies use the outputs to inform capital planning, asset strategy and risk prioritisation.
What happens in Year 2 and beyond?
You reuse the same system.
Most companies find Year 2 effort drops significantly because:
- governance is already defined
- assumptions are documented
- disclosure logic is established
Updates focus on data, judgement changes and refinement rather than rebuilding from scratch.
How do we know if this is the right fit for us?
The best way is a short walkthrough.
We will show you:
- how the system is structured
- what internal effort is required
- where it fits and where it does not
No sales pitch.
Just clarity.
