Rising Waters, Rising Risks
Sustainaccount’s Framework for Regulatory-Aligned Flood Exposure Assessment
River flooding is one of Europe’s most significant and costly natural hazards — and the risks are increasing.
In our latest white paper, “Rising Waters, Rising Risks: Rethinking Flood Exposure in a Changing Climate”, Sustainaccount presents a regulatory-aligned, scenario-based methodology for assessing river flood risk at the asset level.
This publication explains how forward-looking flood modelling, aligned with EU regulatory frameworks, can transform physical climate risk from a compliance burden into strategic intelligence.

Why Flood Risk Needs to Be Rethought
The July 2021 floods in Germany, which caused approximately €33 billion in economic losses, exposed the scale of systemic flood vulnerability in Europe.
At the same time, regulatory expectations have intensified:
- The EU Taxonomy Regulation (2020/852) demands climate risk and vulnerability assessments for taxonomy-aligned activities.
- The Corporate Sustainability Reporting Directive (CSRD) requires companies to disclose material physical climate risks — including river flooding.
- The EU Floods Directive (2007/60/EC) requires systematic flood risk identification, mapping, and management planning.
Yet many available flood tools are either:
- Too engineering-focused for portfolio screening; or
- Too high-level to support financial risk quantification.
Our methodology bridges that gap.
What This White Paper Delivers
This 37-page technical paper provides:
- A Regulatory-Integrated Framework to ensure assessments are suitable for both compliance and capital allocation decisions.
- A Structured walk-through our 4-Step Flood Modelling Process
From Flood Depth to Financial Risk
What differentiates Sustainaccount’s framework is the integration of:
- Scenario-based hazard modelling
- Flood protection adjustment
- Asset-level inundation modelling
- Climate Value at Risk (CVaR) quantification
The result is a direct translation of flood depth into financial exposure metrics, enabling:
- Portfolio-level screening
- Individual asset assessment
- Capital allocation guidance
- Resilience investment prioritisation
For assets near but not within flood zones, proximity risk (≤200 m) is also captured — recognising operational disruption risk even without direct inundation.
Who Should Read This?
This paper is particularly relevant for:
- Infrastructure asset managers
- Real estate investors
- Insurers and reinsurers
- Banks and financial institutions
- Corporate sustainability teams
- ESG and risk officers
- Climate risk consultants
- Public authorities and planning agencies
Anyone required to assess, disclose, or manage physical climate risk exposure will benefit from this framework.
Why This Matters Now
As climate extremes intensify and EU disclosure frameworks mature, flood risk modelling must:
- Be spatially precise
- Be scenario-based
- Incorporate protection infrastructure
- Translate hazard into financial materiality
- Align with EU regulatory frameworks
This white paper demonstrates how to achieve all five.
