AASB S2 / IFRS S2
Climate risk quantification built to survive assurance.
Australia’s first cohort of AASB S2 reporters described their climate risk - but most stopped short of a defensible dollar figure. Meridian produces one: physical and transition risk quantified in your reporting currency across NGFS, IEA and IPCC scenarios, with every figure traceable and every adjustment recorded for assurance.

Who it’s for
Built for Australia’s next wave of climate reporters.
AASB S2 climate reporting is mandatory and phases in by company size. Group 1 began in 2025, and Groups 2 and 3 - the mid-market - follow. Meridian takes you a step beyond describing your climate risk: a defensible dollar figure, ready for where reporting is heading, without a consultancy budget.
Group 1

A company is in a group if it meets at least two of the three thresholds. NGER reporters and asset owners with A$5bn or more under management are brought in separately. This is a guide, not legal advice.

Process
Five steps from company to quantified climate risk.
The pipeline mirrors how a senior analyst works - with a mandatory human sign-off before the numbers are published.
Company input
Sector, geography and financial baseline captured once - cached and reusable for 12 months.
Scenario selection
Choose pathways and horizons across NGFS Phase V, IEA WEO 2025 and IPCC AR6 scenario sets. Channel coefficients cite the IEA edition they derive from (e.g. NZE 2021, WEO 2023).
Transmission channel mapping
Physical and transition drivers mapped to financial line items with weighted, sourced coefficients.
Gate 1 preparer sign-off
The company confirms its own inputs and explicitly owns any change it makes to Meridian's methodology - every adjustment carries a documented reason - before the numbers are published.
Modelled best-estimate output
Your expected annual loss, plus the upside opportunities. Asset-level models run wherever your data supports them, with sourced coefficients filling the gaps. Every figure maps to the line item it affects and comes with a 90% range and full citations.
Platform
Built for the scrutiny your numbers will face.
Defensible dollars, not narrative
Physical and transition risk in one dollar figure.
Damage models for hazards, discounted cash-flow for carbon and demand, with a modelled range around every number rather than false precision. Bushfire is calibrated to verified realised losses; cyclone, flood and coastal are anchored to the published science until enough verified events allow the same. Coefficients grounded in and back-tested against peer disclosures - the number capital markets and ASIC are now asking for.

Scientific traceability
Every coefficient is cited to its source - IPCC AR6 chapter, NGFS Phase V variable, IEA WEO table, Australian Climate Service grid - down to the section, or disclosed as a documented Meridian judgment - nothing unlabelled reaches your disclosure.

Built for assurance
Every number traces to its source and its version.
Each input, adjustment and sign-off is recorded in a trail that can't be edited after the fact, and every figure is locked to the exact data and model version behind it - so your assurer can re-check any number. The engine and methodology themselves are built for central, independent assurance: an ASAE 3402 service report (an independent auditor's report on how a service is run) that Meridian is putting in place for your assurer to rely on.

Risks and opportunities, both quantified
Most first-year disclosures put a number on downside risk only, and many disclose no opportunities at all. Meridian quantifies the upside - resource efficiency, new markets, adaptation - alongside the risk, as AASB S2 requires.
Downside + upside, on the same basis
Australian-native by design
Australian Climate Service 5 km grids, at your sites.
Bushfire, heat, flood and cyclone hazards are read at each site, or its postcode where no address resolves, with an uncertainty range rather than a single number. Bushfire damage is checked against real Australian fire losses. AASB S2 phase-in is keyed to your size, and materiality uses a documented threshold. Not a global model bent to fit.

Cache-first efficiency
Reference data - scenarios, coefficients, sources - is cached indefinitely; company data for 12 months. Repeat analyses take minutes, not another full project - and next year is an update, not a restart.
