Sample Evidence Bundle

An AtlasCore evidence bundle is the audit-ready output package generated for climate disclosure reporting. This page walks through each file in the bundle.

Bundle files

Every disclosure bundle contains seven files:

File	Size (typical)	Purpose
report.json	15–50 KB	Structured disclosure data with AASB S2 section mapping
report.md	5–15 KB	Human-readable Markdown narrative
report.pdf	50–200 KB	Formatted PDF for distribution
report.xlsx	30–100 KB	Excel workbook with data tables
provenance.json	3–10 KB	Complete data lineage and source metadata
checksums.json	1 KB	SHA-256 hashes of all bundle files
bundle.zip	100–400 KB	All files packaged together

File-by-file walkthrough

report.json

The structured data backbone of the bundle. Contains:

• Company metadata — ABN, name, entity resolution confidence
• Metrics and targets — Scope 1/2 emissions, emission factors, grid intensity
• Risk management — physical risk indicators, transition context
• Market-based Scope 2 — evidence status and matched instruments (when available)
• Targets — emission reduction targets and progress (when declared)
• Framework coverage — AASB S2 paragraph-level coverage from the pack registry
• Reference context — methodology, reporting groups, statistical reference data

report.pdf

A formatted report suitable for distribution to stakeholders. Includes the same content as report.json in a human-readable layout with tables, charts, and section headings mapped to AASB S2 pillars.

report.xlsx

An Excel workbook with:

• Data tables for each section
• Source citations per value
• Optional assurance metadata (when workpaper_mode=assurance is used)
• Reference context appendix (when pack_id is supplied)

provenance.json

Audit trail recording:

• Which data sources were used (NGA, AEMO, CER NGER, BOM SILO)
• Snapshot versions and extraction timestamps
• Evidence hashes for each input source
• The rollup basis (public or declared boundary)

checksums.json

SHA-256 hashes for every file in the bundle. Enables tamper detection — if any file is modified after generation, the checksum won't match.
