Climate Risk Advisory

Learn how your organization can benefit from Climate Risk Advisory. 

Why is responding to climate change important now?  

Extreme weather attributed to $380B of economic loss in 2023. As climate change impacts the frequency and severity of these events, businesses, communities and governments must evolve to better protect their people and property.  

Rising claims costs, increasing regulatory scrutiny and changing consumer preferences mean organizations face emerging pressures to adjust their climate strategies to both future-proof their operations and capture growth opportunities.

How Aon Can Help 

Aon’s Climate Risk Advisory practice helps clients make better decisions about their climate-related financial risks - delivering data and expertise to unlock capital and make markets to drive the transition.

We specialize in financial institutions, public sector entities and firms with large real estate holdings, enabling organizations to capitalize on strategic opportunities to:

  • Quantify and Mitigate Physical Risk

    Our physical risk modeling tools – built on our natural catastrophe and risk engineering expertise – assess the exposure of client assets to climate change. Our actuarial and analytics capabilities allow us to quantify the value at risk under warming scenarios and evaluate vulnerabilities in the portfolio to develop tailor-made mitigation strategies for our clients.

  • Establish a Climate Risk Management Strategy

    With deep expertise helping organizations identify, assess and manage risk, we equip clients with leading practices in developing and embedding climate risk strategy. We combine enterprise risk management capability, climate modelling expertise and risk financing knowledge to help clients develop holistic climate risk frameworks and processes for enhanced decision-making support.

  • Meet Reporting and Disclosure Obligations

    We take a multi-disciplinary approach to support clients in meeting disclosure requirements with a combination of tools and methodologies – underpinned by scenario analysis and risk quantification to support decision-making. We also embed findings in the commercial context of our clients, providing practical insights beyond compliance with reporting standards.

  • Make Better Risk Transfer Decisions

    Our analytics capabilities and insurance knowledge allow us to design innovative solutions for climate-related volatility. This can include using captive vehicles for risks that may be traditionally difficult to insure, providing solutions to accelerate the transition and ensuring risk exposures are reflected in optimal insurance pricing.

  • Navigate Transition Risk and Identify Growth Opportunities

    Our approach to transition risk builds on our deep risk advisory expertise to support clients in managing potential risks associated with various transition scenarios and in surfacing opportunities. As the global economy restructures to meet targets to limit global warming, our practical approach looks to highlight opportunities to help companies position themselves in a low-carbon economy.

By combining climate data with three decades of experience using and evaluating catastrophe and climate modeling solutions, we offer a one-stop-shop for climate risk management and transfer. 


Only 31 percent of the $380 billion in global economic losses from natural disasters were covered by insurance in 2023 — on par with the long-term average protection gap.
