Greenly is a global carbon accounting platform for SMEs and enterprises. Its announced merger with Normative broadens its methodology and reporting coverage. Australian buyers should compare that platform and service model with the source-data work, ASRS support and review process they need. We build a competing Australian tool, so weigh our view accordingly.
Where Greenly fits
Greenly is a global carbon accounting platform for SMEs and enterprises. It combines software with climate expertise and support. Greenly and Normative announced their merger in September 2026, so older comparisons that treat them as separate options are now out of date.
What to check for Australian reporting
Australian reporting has several requirements worth checking directly. NGER has its own rules, while AASB S2 sets the climate disclosures companies must make. Ask each vendor which Australian emission factors it maintains, how it handles NGER data, how it structures AASB S2 disclosures and what evidence it keeps for assurance.
The alternatives, by fit
The right alternative depends on the reporting work and the support you need. There is no ranking within each group:
| If you report | Alternatives that fit | Why |
|---|---|---|
| A consolidated Australian ASRS inventory, including overseas entities | CO2 Lab, Sumday, Avarni | Australian-built options with local reporting and implementation workflows |
| A broader sustainability programme across several reporting regimes | Watershed, Persefoni (and Greenly itself) | Broader platform coverage across measurement, reporting and decarbonisation |
For an Australian ASRS inventory, compare what the software completes and what remains with your team or adviser. CO2 Lab, which we build, pairs its carbon accounting platform with an AI Sustainability Analyst. It processes data from Xero, NetSuite and source documents, then returns the ledger and evidence for review. This workflow supports experienced teams and multi-entity groups, including those with overseas operations.
“For Australian assurance, check the factors, source records and calculation trail behind the emissions number, regardless of where the software was built.”
How to check Australian fit
Greenly combines software with climate expertise, so compare the product and service together. Give each vendor a supplier invoice and ask what the software completes, what its team completes and what remains with you. Then verify its ASRS, NGER and Australian factor support. The calculation should also retain suitable source evidence. Our software selection checklist covers the questions in more detail.
Where CO2 Lab fits as a Greenly alternative. It is built around the data work behind an Australian ASRS inventory:

Bring a bill and a ledger extract. See how much work is completed before review, then inspect the source, factor and reasoning behind the result.
