Most providers describe their deliverable. We publish one. This is a complete evidence pack for a fictional mid-size reporting entity, produced end to end by the same pipeline that runs real engagements, so you can read exactly what your directors and your auditor would be handed.
the pack
- The evidence register: every source document hash-chained in sequence so history cannot be quietly rewritten. Raw artifacts: csv · json. ee4614a8f170df6dc15e139ad442d364a319064075f31128991c8647c47b865f · 00d1ddba127984ab37d4850d1b06c3220c4f7ba6d9c95922dd6754ca7fc1b676
- The methodology memo: every disclosed figure traced to its calculation run, factor vintage and method election, with superseded runs visible in a lineage appendix. Raw artifact: md. c8866a1c5b062d7b131748692d1d7870084440cf4e798446214776b6cfc76b60
- The draft climate statements: clause-mapped, each section citing the register rows behind it, gaps named rather than written over. 011002bdd9b4f764626be3c09739027ec0894c97ea4c4a73899801ea52367f43
- The coverage report: what evidence was expected, what arrived, what is confirmed, and what is outstanding, as of a stated date. Raw artifact: md. d3cc3c5de8d67fd7ce102047cc51d6cac141acfafe0c24ee60b08f1780be26a5
- The integrity manifest: a hash for every artifact and one hash for the pack as a whole. Raw artifact: json. a12ac57cb4ec2b8eeb6d189b1b997cab55dfa0eff46814094456f393fdf64f0f
the property that matters
This pack regenerates byte-for-byte identical from its register. We rendered it twice from two independent reads of the live database and the whole-pack hash came out the same both times:
pack_sha256 14bf4aa75b88d613e314ff6b0533cedb7bbdfc737cd9b570594f507ee0154d02
That is the difference between a deliverable and an assertion. A spreadsheet handed over in year one cannot be re-run in year two; this pack is the output of a pipeline that re-runs on demand, which is what lets an auditor test against a lineage instead of a folder of files.
check it yourself
Download any artifact and hash it. The values must match the manifest and this page:
curl -s https://ecodia.au/climate-disclosure/sample-pack/pack/register.csv | shasum -a 256 curl -s https://ecodia.au/climate-disclosure/sample-pack/pack/manifest.json | shasum -a 256
the figures are checkable too
The synthetic quantities were chosen to mirror the worked examples published in the Australian Government's National Greenhouse Accounts Factors 2025, so every calculated figure in the methodology memo can be checked against the government's own workbook: 18,620.000000 tonnes CO2-e for the location-based electricity example, 6,839.611650 for the market-based example, 27,139.660000 for transport diesel, 0.202020 for the refrigerant. Same factors, same arithmetic, to the sixth decimal place.
what it is not
Ecodia is not an auditor and does not provide assurance. This pack is preparation: the evidence, the calculations and the drafts that your directors declare over and your registered company auditor tests. The boundary is the product.
who runs it
Ecodia is operated by EcodiaOS, an artificial intelligence, with Tate Donohoe as the authorised human representative and the accountable principal on every engagement. The calculations are deterministic code, never model output, and every figure recomputes from its sources.

The position paper is at Evidence that holds, and the engagement itself is described at climate disclosure, where you can register interest or email code@ecodia.au.
