AASB S2 Mapping

AASB S2 (Climate-related Financial Disclosures) requires Australian entities to disclose climate-related risks and opportunities across four pillars: Governance, Strategy, Risk Management, and Metrics and Targets. AtlasCore maps its data outputs to specific AASB S2 paragraphs.

Four pillars

Pillar	AASB S2 paragraphs	AtlasCore support
Governance	Aus5.1–Aus10.1	Placeholder — requires entity-authored narrative
Strategy	Aus11.1–Aus22.1	Physical risk indicators, transition context
Risk Management	Aus25.1–Aus27.1	Data-sourced risk identification and assessment
Metrics and Targets	Aus29.1–Aus34.1	Emission factors, company profiles, evidence bundles

What AtlasCore provides

Metrics and Targets (strongest coverage)

AtlasCore provides the quantitative data backbone for Metrics and Targets disclosures:

• Scope 1 and 2 emissions — NGA-sourced factors, NGER corporate emissions, AEMO grid intensity
• Evidence bundles — audit-ready five-file bundles mapping to paragraph requirements
• Emission targets — tenant-authored target storage with deterministic progress tracking
• Organisational boundaries — declarative boundary definitions (equity share, operational control, financial control)

Risk Management (data-supported coverage)

• Physical risk — BOM SILO climate data (temperature, rainfall, extreme heat days) for company and site locations
• Transition risk — config-driven sector intensity, Safeguard exposure, and regulatory trajectory assessment
• Water stress — BOM water balance data with sector-aware intensity classification (when ingested)

Strategy (context and projections)

• Climate context — physical risk indicators and statistical reference data for strategic narrative support
• Scenario projections — CMIP6-derived climate projections (RCP 2.6/4.5/8.5) for 2030, 2050, and 2070 horizons when ingested
• Transition risk — sector-based transition risk assessment from ANZSIC classification, Safeguard coverage, and benchmark position

Governance (not covered)

Governance disclosures require entity-specific narrative about board oversight, management roles, and internal processes. This is outside AtlasCore's scope.

Framework registry

AtlasCore maintains a versioned registry of AASB S2 requirements that tracks coverage status per paragraph:

curl -H "Authorization: Bearer ac_test_key" \
  "https://api.atlascore.com.au/v1/packs/au_climate_disclosure/frameworks/aasb-s2/requirements"

The registry includes:

• Supported AASB S2 versions (September 2024 operative, December 2025 amended)
• Paragraph-level coverage status (data-supported, context-only, placeholder, not applicable)
• Stable evidence_hash for each registry version

Reporting groups and timing

AASB S2 applies to different entity sizes on a phased schedule:

Group	Begins	Size thresholds (2 of 3)
Group 1	1 January 2025	Revenue > $500M, Assets > $1B, Employees > 500
Group 2	1 July 2026	Revenue > $200M, Assets > $500M, Employees > 250
Group 3	1 July 2027	Revenue > $50M, Assets > $25M, Employees > 100

Assurance requirements

Period	Requirement
Before 1 July 2030	Review or audit to the extent required by AUASB (ASSA 5000 / ASSA 5010)
On or after 1 July 2030	Full audit (ASSA 5000)

AtlasCore's evidence bundles, provenance chain, and evidence hashing are designed to support the assurance requirements under ISSA 5000 / ASSA 5000.

Coverage is descriptive

AtlasCore's framework registry provides descriptive coverage status. It does not imply filing readiness or legal sufficiency — entities should seek professional advice for their specific reporting obligations.
