One Concern

What is One Concern?

One Concern is a cloud-based platform for disaster and physical climate resilience intelligence. It models how events such as floods, earthquakes and extreme weather affect properties, infrastructure and operations, producing estimates such as downtime and portfolio risk.

Key capabilities of One Concern

• Downtime estimates: how long assets or operations could be disrupted.
• Infrastructure dependency modeling: how failures in one system cascade to others.
• Portfolio risk analytics: aggregate risk across properties.
• Scenario analysis: test hazard scenarios.
• Satellite data analysis: uses remote-sensing inputs.
• Audit-ready methodologies: documented methods for review.

How One Concern works

Users bring a portfolio or asset list, One Concern applies hazard and infrastructure models to estimate impact and recovery, and outputs scores and scenario results. Its resilience scores are being brought into WTW's insurance client tools through an alliance.

Who uses One Concern?

Insurers, reinsurers, brokers, real estate and infrastructure owners and public agencies that need to quantify climate and disaster exposure.

SAS Viya and Sisense are general-purpose analytics platforms that can host risk analysis but do not ship disaster impact models. Pachama focuses on carbon credit verification, which is a different climate problem. One Concern is specific to physical climate risk and resilience.
