AASB S2 climate disclosure
Produce the physical risk evidence behind an AASB S2 disclosure — governance, strategy, risk management, metrics and targets — from a site list and Australia's open data.
Climate risk
Physical climate risk assessment
Asset-level physical climate risk screening across flood, bushfire, coastal recession and extreme heat, using Australian open hazard data and CMIP6 scenarios.
Most physical climate risk products answer a question you did not ask. They give you a score between one and five, decline to explain it, and leave you to defend it in an audit committee meeting.
Screening is a triage exercise. The useful output is not a score — it is a shortlist: which sites justify a real engineering study, and which ones you can stop worrying about.
Hazards and where the data comes from
Which of our sites move from moderate to high flood risk between SSP2-4.5 and SSP5-8.5 at 2050?
| Site | LGA | SSP2-4.5 | SSP5-8.5 |
|---|---|---|---|
| DC-014 Wagga | Wagga Wagga | Moderate | High |
| RT-221 Lismore | Lismore | High | High |
| OF-006 Maribyrnong | Maribyrnong | Moderate | High |
nsw_flood_studiescadastrecmip6Flood. Council and state flood studies, flood planning areas, and recorded historical extents. Coverage is genuinely patchy across Australia and the assessment says so per site rather than filling the gap silently.
Bushfire. Geoscience Australia's national bushfire boundaries plus state bushfire-prone land mapping, combined with slope and vegetation from the national elevation and land cover datasets.
Coastal. Digital Earth Australia Coastlines gives measured shoreline change since 1988; sea level rise projections extend it forward.
Extreme heat. SILO gridded observations for the baseline, CMIP6 downscaled projections for days above thresholds under each scenario.
Scenario handling
Two scenarios is the floor AASB S2 sets, and SSP2-4.5 with SSP5-8.5 is the pairing most Australian reporters land on. Horizons default to 2030, 2050 and 2070. Both the scenario set and the horizons are parameters, not hard-coded assumptions, and they appear in the methodology appendix alongside the results.
What you get back
A per-site record with a hazard rating, the layer that produced it, the distance to the nearest hazard boundary, and a confidence flag reflecting the quality of the underlying study. Portfolio rollups aggregate that, and the map view shows the parcel against the hazard layer so you can see what the join actually did.
Where a site has no usable study, it is flagged as unassessed. That is a more honest answer than a number.
Frequently asked
How is this different from XDI, Jupiter or Climate X?
Those platforms are excellent and priced for large financial institutions. Zenancy targets the mid-market with open Australian data and a transparent method, and shows the query behind every number instead of returning a proprietary score.
What hazards are covered?
Riverine and flash flooding, bushfire, coastal inundation and recession, and extreme heat. Drought and cyclone are on the roadmap once the underlying national layers are harmonised.
Can I screen thousands of sites?
Yes. Screening runs in a sandboxed DuckDB environment over parquet, so portfolio size is a cost question rather than a feasibility one.
