A tool for thinking
Climate Risk Prioritiser
Screen council assets for climate risk, look beyond condition to loss of service, flag compound hazards and rank adaptation actions across your portfolio. It covers Greater Sydney and uses official NSW map data at each asset's location.
An illustrative screening tool for learning and discussion. It is not a substitute for a full climate risk assessment.
How it works
- Asset: describe the service and use the highest of five criticality factors.
- Location: check the site against mapped hazards and council-wide disaster history.
- Hazard screening: Low exposure together with Low vulnerability screens a hazard out.
- Existing controls: effective controls mean monitor; otherwise rate likelihood with current controls.
- Risk rating: likelihood × consequence; the highest hazard band drives the asset rating, with the product breaking ties.
- Compound hazards: identify interactions and flag them for detailed assessment.
- Adaptation plan: set actions, triggers, timing and expected ratings. High, Very high and compound risks require a plan.
- Portfolio: compare risk priority and action value. A stress test remains separate from the planning scenario.
In the 5 × 5 rating grid, products 1 to 4 are Low, 5 to 9 Medium, 10 to 16 High and 20 to 25 Very high. Catastrophic consequence sets a minimum High rating. Suggestions are prompts, not automatic scores.
Action value sums current minus expected likelihood × consequence for rated hazards with entered expected values in the planning scenario, then divides by cost / $100,000. Positive reductions at zero cost are labelled No-cost action. Negative totals are labelled Increases risk. Missing expected values remain pending.
Tsunami, the coastal hazards and Ocean acidification are listed for Coastal structures, points in the mapped coastal zone, assets in or beside tidal water, or when you tick Show coastal hazards.
Hazard layers are official map data at the point and are for screening only. Declared disasters are council-wide recovery declarations, not site-level hazard observations. History starts in 2011; earlier records are incomplete and 2026 is partial. Missing map layers or declarations do not mean no hazard.
