Aon, a global professional services firm focused on risk and insurance-related consulting, has released an updated version of its climate risk monitoring platform, enhancing its ability to quantify physical climate risks and support decision-making across industries.
The latest version, CRM 3.0, introduces heat stress analysis to assess how combinations of temperature, humidity and exposure affect health, productivity and broader economic performance.
Aon emphasized that this addition is intended to give organizations a clearer understanding of how rising temperatures may impact people and operations.
The platform also integrates new cooling demand functionality, reflecting the increasing reliance on cooling systems as global temperatures rise.
Aon noted that this development is important for understanding how cooling-related energy use can increase emissions if not carefully managed, especially as demand grows in sectors such as artificial intelligence-enabled data centers.
Aon has also extended drought and water stress models in CRM 3.0. The update combines changes in rainfall patterns with rising temperatures to better reflect future water shortage risks and their operational consequences, the company said.
Liz Henderson, head of climate risk consulting at Aon, commented: “As we look to 2026 Climate and Disaster Insights Reportnatural climate risks continue to evolve, with implications for communities, policymakers and insurance markets.
“Heat stress, growing cooling needs and rising water usage are quickly becoming daily challenges for businesses and communities, impacting people, energy systems and IT infrastructure, especially as more data centers are built with increased use of artificial intelligence. By quantifying these impacts, organizations can better protect uptime, manage costs and build resiliency for a hotter, more demanding future.”
Aon also noted further enhancements to CRM 3.0, including more detailed hazard data designed to support site-specific analysis across assets and portfolios. The updated system now places greater emphasis on observed weather events, rather than relying solely on reconstructed historical models, with the aim of better reflecting real conditions, the company explained.
In addition, Aon has refined its baseline climate data using recent observational data and introduced bias correction techniques to improve the consistency between climate models and observed trends, helping to improve the consistency between current and predicted conditions.
Usability has also been improved, with Aon enabling clients to upload data directly to the platform, reducing reliance on consultancy-led workflows and allowing faster iteration of risk assessments across business units.
CRM 3.0 further introduces a global hazard mapping tool, which Aon says provides a globally consistent view of climate-related risks across multiple hazards, extending long-term forecasts to the end of the century.
Aon said CRM 3.0 is designed to support insurers, reinsurers and public sector organizations to improve risk selection, pricing and reinsurance planning through more detailed climate risk analysis. It is part of the company’s wider portfolio of disaster modeling, risk management expertise and academic collaborations aimed at improving understanding of natural disaster risks.
