AUSTRALIAN CLIMATE DATA INFRASTRUCTURE
One API for AASB S2 Compliance
Production-grade emission factors, entity-level climate profiles, and deterministic risk assessment — built on authoritative government data.
- Scope 1 & 2 emission factors with Scope 3 reference data
- Entity-level climate profiles and physical risk by ABN
- Market-based Scope 2 evidence with GreenPower reference
- Site-level rollups for multi-location portfolios
- SHA-256 evidence hashes and NGA source tracing
- XLSX assurance workpapers, PDF reports, disclosure bundles
- HMAC-signed webhooks with retry-safe delivery
Group 1 entities filing now. Group 2 from July 2026.

}Fragmented Data
Six agencies, zero unified API. Every jurisdiction publishes differently — different formats, different update cycles, different access methods.
Manual Compliance
NGA workbooks, NGER spreadsheets, AEMO CSVs — manually downloaded, manually reconciled, manually outdated.
Deadline Pressure
AASB S2 is mandatory. Group 1 entities are filing now. Group 2 begins July 2026. Group 3 follows in 2027.

Consume it your way
REST API
JSON responses with evidence hashes and provenance metadata. Batch up to 50 ABNs or 200 factors per call.
Working Papers
Multi-sheet workbooks with optional assurance mode — pedigree indicators, quality grades, and engagement fields for Big 4 workflows.
Disclosure Bundles
Complete AASB S2 packages: JSON, Markdown, PDF, XLSX, provenance manifest, and SHA-256 checksums — in a single ZIP.
Webhooks
HMAC-signed push notifications when emission factors, grid intensity, or entity data updates. Retry-safe delivery with full event history.
Built for audit
Evidence Hashes
SHA-256 hash on every response. Re-compute offline to verify nothing changed.
Source Tracing
Every factor traces to the exact table, sheet, and row in the NGA workbook.
Pedigree Scoring
ISO-aligned data quality indicators: reliability, completeness, temporal, geographical, technological.
Versioned Snapshots
Reproducible queries pinned to ingestion snapshots. Roll back without data loss.
Authoritative Australian government data. Normalised. Versioned. One API.
