Carbonly vs Greener: Choosing an Australian Carbon Reporting Platform for AASB S2
Greener suits a retail chain with the same six bill formats across 300 stores. Carbonly suits a construction JV where the quantities sit on supplier dockets. Here is how each gets you to an AASB S2 disclosure your assurance provider can trace.
The platform fit for a 300-store retail chain is not the same as the platform fit for a Tier 1 construction joint venture. Both need to file under NGER. Both need AASB S2 climate-related financial disclosures. Both need an audit trail that stands up to ASSA 5010 limited assurance. The data-collection problem underneath, though, is shaped completely differently.
A distributed retail network has hundreds of small sites, standardised utility bills across a handful of retailers, and material diversity that is comparatively low. A construction JV has a handful of large sites, dozens of suppliers with wildly different invoice formats, subcontractor fuel and equipment records, and material inputs (concrete, steel, aggregate, AdBlue) that dominate the emissions picture. Same disclosure regime, different data problem.
That is the split we want to unpack in this comparison, because it is the honest way to answer "Carbonly or Greener?" without pretending one product wins every buyer.
Where Greener sits in the market
Greener is a legitimate Australian carbon reporting platform. Everything we say about it here is drawn from public materials as at September 2026. We have not run a hands-on evaluation, so read this as a description of published positioning rather than a tested review, and confirm anything decision-critical with the vendor.
On that public positioning, the design centre appears to be governance-first: evidence chains, workflow across a sustainability team, and the pattern-matching that works when your data flows look similar across many locations. If you are a retailer operating hundreds of stores under a single brand, needing to consolidate utility and waste data across those stores into an AASB S2 disclosure that survives assurance, that is a real strength aimed at a real buyer profile, and Greener belongs on your shortlist.
Where Carbonly sits
Carbonly's centre of gravity is different. The design constraint was set from day one against construction paperwork: a Tier 1 civil operation generates more fuel dockets, delivery notes and subcontractor invoices in a quarter than a reporting team can key in by hand. The data does not arrive as clean utility bills. It arrives as supplier documents with wildly variable formats, and the reporter cannot control which formats show up.
The result for that reporter is one ledger record per docket, with the quantity read from the supplier's document rather than keyed in. That shaped the AI Document Engine toward source-document extraction across 8 file formats (PDF, Word, PowerPoint, Excel, CSV, RTF, image, scanned), and drove the 5-tier material matching against the NGA 2025 factor library or a construction EPD factor library. The buyer profile that matches this shape is construction, mining, property, infrastructure, and manufacturing. That is where physical activity data lives in supplier invoices and where JV structures dominate the reporting boundary.
Head-to-head
The most useful thing we can put in front of a buyer is a fair comparison of the shape of each product, not a scorecard. Both platforms answer the compliance question. The question is which one fits your data-collection problem.
The Greener column reflects what we could find in public documentation as at September 2026. It says what is documented publicly, not what the product can or cannot do internally. Put every row to the vendor before you rely on it.
| Dimension | Greener (per public materials, Sept 2026) | Carbonly |
|---|---|---|
| Primary buyer profile | Retail chains, complex enterprise sectors, governance-heavy sustainability teams | Construction, mining, property, infrastructure, manufacturing, resources |
| Data-source model | Evidence chain across store networks and enterprise sites | Source-document extraction across supplier invoices, dockets, meter reads, subcontractor records |
| Scope 1/2/3 coverage | All three scopes with 15 Scope 3 subcategories (standard for AASB S2) | All three scopes with 15 Scope 3 subcategories |
| NGER Measurement Determination fit | Described in public materials; depth not verified by us | NGA factor library; NGER facility and corporate-group threshold status computed from the ledger |
| AASB S2 assurance readiness | Governance and evidence-chain focus | Evidence pack for assurance, emission factor version recorded per record, period locking with restatement reasons, seven-year retention |
| JV consolidation | No public documentation found of multi-method consolidation (Sept 2026) | Operational, financial, and equity-share methods built in |
| Pricing model | Greener does not publish a public price list that we could find; confirm directly with the vendor | Per-project (Small/Medium/Large/Enterprise) with $100/month workspace minimum, published on our pricing page |
One table is enough. The nuance behind each row matters more than the row itself, so let's walk the important ones.
Where Greener is genuinely the better fit
If you are running a national retail chain with 200-plus small stores, receiving similar electricity, gas, and waste bills from a small number of retailers, and your main AASB S2 challenge is governance workflow across a large sustainability team, the shape Greener's public materials describe matches your problem more directly than ours does. That is not a euphemism. If your data flow is "same six bill formats replicated 300 times", you do not need document-extraction depth, you need governance rigour and rollup discipline.
Similarly, if your team is structured around a central sustainability function that assigns evidence-collection tasks to store managers or regional leads, and the AASB S2 disclosure is the primary deliverable rather than the NGER submission, the workflow-first design pattern that a governance-heavy product tends to build is the right fit.
Where Carbonly is the better fit
The buyer we optimise for is different. A Tier 1 construction company running a road project in NSW is not receiving 300 identical utility bills. It is receiving Boral concrete delivery notes, Holcim invoices, InfraBuild steel dockets, subcontractor fuel receipts from every diesel supplier within 200 km of the site, AdBlue invoices, aggregate delivery notes, and equipment hire records. Each supplier's format is different. Many of them arrive as scanned PDFs or photographed dockets emailed by a site supervisor.
That is a source-document extraction problem, not an evidence-chain rollup problem. The document engine keeps one record per docket on multi-docket invoices and keeps the verbatim line text as evidence. The 5-tier material matching runs each extracted line item against NGA factors or a construction EPD factor library, and low-confidence matches go to a reviewer. When a reviewer corrects a match, the line text is saved as an alias for your organisation, so later documents with the same wording match through it.
JV consolidation is where construction and resources buyers pause
Australian resources, infrastructure, and construction don't operate through clean single-entity reporting boundaries. They operate through joint ventures. A road build under a JV. A gas project under a JV. A mining tenement under a JV. That is the reporting shape that AASB S2 and NGER both have to accommodate, and it does not fit a standard corporate consolidation model.
Carbonly's JV consolidation supports operational, financial, and equity-share methods built into the ledger. You can consolidate the same underlying emissions record under three different methods and produce three different views for three different disclosure obligations. For a construction or resources buyer, this can be the feature that decides the platform choice.
What a construction or resources reporter gets
If your data flow includes any of the following, we think Carbonly's shape is likely closer to what you need than a retail-oriented platform:
- Concrete delivery notes with strength grade, volume, and supplier plant references that need to match against embodied carbon factors
- Fuel dockets from multiple suppliers with different columns for litres, product code, and fuel type
- Subcontractor fuel and equipment data that has to be collected from suppliers project by project
The construction data-entry problem, where the quantity that matters sits on a supplier document rather than in a ledger, is the workload these features were architected against. If your buying committee includes a project accountant who has ever had to reconcile a subcontractor fuel claim against a JV cost-share model, they will recognise this shape immediately.
What your assurance provider sees under ASSA 5010
Both platforms aim at ASSA 5010 limited assurance readiness for AASB S2 disclosures. The question is what the assurance provider sees when they walk your trace.
On Carbonly, each record in the ledger links back to its source document, and the evidence pack bundles that trace for the assurance provider. Each record stores the emission factor version applied, so a newer factor edition doesn't quietly change historical numbers. Records are retained for seven years, longer than the five-year NGER record-keeping obligation.
None of that is unique in principle. Every serious platform is heading in this direction. The specificity matters because the assurance provider does not care about the marketing description of "audit-ready", they care about the exact evidence they can put in front of a partner's review.
Where Greener may fit better than Carbonly
We want to be honest here rather than pretend there is a universal winner. If your organisation is a large multi-store retail chain, if your utility bill formats are homogeneous across hundreds of locations, if your AASB S2 disclosure work is framed primarily as a governance and workflow challenge rather than a document extraction challenge, and if your sustainability team is structured around central rollup discipline, the product shape Greener describes publicly maps more directly to that reality.
We would rather you buy the platform that fits your data problem than sign onto ours because a comparison blog told you to. Assurance costs go up quickly when the platform is fighting the shape of your data.
Consultants are buyers, not competitors
Consultants are not competitors to either product. They are buyers. A sustainability practice choosing a platform will weigh it against the client roster in front of them. A consultancy whose clients are mostly retail and services will lean toward one shape. A consultancy whose clients are mostly construction, resources, and infrastructure will lean toward the other. That is not a fight, it is a category split.
If a consultant is leading your AASB S2 engagement, ask them which platform they have used most recently on a client whose data profile matches yours. They will have a view.
Pricing
Carbonly is priced per-project across Small, Medium, Large, and Enterprise tiers, with a $100/month workspace minimum. That structure lets an SME start on the same platform that an ASX-listed reporter uses, without a leap in cost that scares smaller buyers off. As the project scope grows, the pricing grows with it.
Greener does not publish a public price list that we could find as at September 2026, and we won't put numbers on a competitor's pricing that we can't substantiate. If pricing is a decision-critical factor for your buying committee, ask both vendors for a written quote against the same scope of work: number of sites, number of documents per quarter, number of user seats, level of assurance the disclosure will be taken to. A like-for-like quote is the only fair way to compare.
The way to decide
The answer is not universal. In our view, if your organisation is 80% retail-shaped, Greener is likely the better platform. If your organisation is 80% construction, mining, property, or infrastructure-shaped, Carbonly is likely the better platform. Most Australian mid-market reporters sit closer to one end or the other than they realise.
The practical way to make the call is to run a 3-month pilot on a single site or single store-cluster with each platform. Push real supplier documents through. Have the assurance provider walk the trace under ASSA 5010 at the end of the pilot on both platforms and tell you which one they can sign more easily. That is the answer. The rest is marketing.
If you want to run that pilot with Carbonly, email hello@carbonly.ai and we will set up a workspace on your NGER register and put your real supplier documents through the AI Document Engine. If Greener's shape fits your problem better, we would rather you know that early than three months into an implementation.
