Carbon Accounting for Australian SMEs
A credible carbon number, without adding another system.
A tender, customer, supplier or board needs emissions data, but the records sit across fuel cards, electricity bills, fleet files and accounting systems. Aethiro turns them into a documented result your Australian small business can use, without a software rollout.

When carbon accounting becomes a business task
Most SMEs arrive with an immediate decision or request, not a desire to study carbon accounting.
A tender or customer needs an answer
You need documented Scope 1, Scope 2 or relevant Scope 3 data in a format the recipient can understand.
Finance or the board needs a baseline
You need a defensible starting point for reporting, investment decisions, customer discussions or future reduction planning.
You are deciding whether to buy software
You need to know whether an annual managed inventory will solve the problem without subscriptions, onboarding and internal administration.
Take the Tender Carbon Readiness Check
See where your tender requirements, customer contracts or supply-chain requests stand, then get a clear path to closing the gaps before the next deadline.

The result is scoped to the request and clear enough for finance, operations and an external reviewer to follow.
Boundary and data map
The entities, sites, reporting period and emission sources included, plus a practical list of the records required.
Carbon inventory
Relevant Scope 1 and Scope 2 emissions, with material Scope 3 categories added where the business need requires them.
Method and assumptions record
Factor sources, calculation workings, exclusions, estimates and professional judgements documented in one traceable record.
A result in the format you need
A business carbon-footprint report, tender summary, customer response or inventory package prepared for later review.
A Hands-On Alternative to Carbon Accounting Software
You need a usable carbon result, not another platform for your team to configure, learn and maintain.
Managed work, not another platform
Aethiro works from the financial and operational records you already hold, then returns a documented, defensible result. There is no software setup, staff training or ongoing subscription required.
When software does make sense
A platform may suit businesses with many sites, data owners and reporting cycles. It still needs a sound boundary, reliable records and internal time to produce a result that can withstand review.

How Carbon Accounting Works for Your SME
Measure what your business emits. Use the number. Move on. Aethiro does the technical work while your team identifies records and confirms how the business operates.
We confirm who needs the result, what must be covered and which entities, sites and reporting period belong inside the boundary.
We map existing records, calculate the relevant Scope 1, Scope 2 and material Scope 3 emissions, and document any gaps or estimates.
You receive the agreed report, tender summary or customer response, with the method and evidence needed to support it.
Records you can normally use
Carbon accounting starts with business activity data, not a new data platform. We confirm the exact request after the boundary is agreed.
Fuel and fleet
Fuel-card exports, supplier invoices, vehicle registers, machinery records and refrigerant service logs.
Electricity and sites
Electricity bills, meter data, site lists and documentation for GreenPower, renewable certificates or power agreements where relevant.
Accounting and purchasing
General-ledger exports, supplier spend, purchased-goods records and waste invoices where material to the required inventory.
Travel, freight and operations
Freight records, business travel, accommodation and other operational data selected after a Scope 3 materiality screen.
A documented method if the result is questioned
Engagements are led by Akshay Dave, an ISO 14064 Lead Verifier Practitioner (TÜV SÜD) with 13 years of heavy-industry experience. Serving regional Queensland supply chains, including Gladstone, Rockhampton, Townsville, Mackay and the Bowen Basin, as well as businesses Australia-wide.
How the carbon inventory is prepared
Aethiro normally applies the operational-control approach under the GHG Protocol Corporate Standard. Each calculation follows activity data multiplied by the applicable emission factor, with results expressed as tonnes of carbon-dioxide equivalent.
Australian National Greenhouse Accounts Factors matching the inventory year are the primary source. IPCC AR5 factors are used where the NGA Factors do not cover the required substance. Scope 3 begins with a materiality screen, so the business does not collect data for categories that do not apply.
The handover records source data, factors, assumptions, estimates, exclusions and calculation workings. This supports later review, but it is not independent assurance. A separate assurance practitioner is required when formal third-party verification is needed.

When another service is the better fit
Match the service to the immediate request rather than commissioning a broader inventory.
Supplier Data Response
Use this when a customer has sent a supplier-emissions questionnaire and the immediate job is to produce a clear, supported response.
Tender-Ready Carbon Snapshot™
Use this when a tender needs a focused carbon position rather than a broader recurring inventory.
Ask about your situation
Describe the request in front of you. Aethiro will explain what scope and records are likely to be required.
