Aon Expands Transition Analytics Offering with TPI Portfolio to help Insurers Navigate Decarbonization

Aon plc (NYSE: AON), a leading global professional services firm today announced the expansion of its transition analytics offering with the launch of TPI Portfolio, an enhancement to its existing Transition Performance Index (TPI). This expanded capability is designed to help insurers more efficiently assess their risk appetite and make underwriting decisions accordingly.

Building on the foundation of Aon’s TPI, which aids hard-to-abate sectors benchmark and evidence transition progress, the TPI Portfolio expands these standardized, portfolio-wide insights across the insurance value chain as a part of Aon’s 3x3 Plan and Risk Capital Strategy. This enables insurers to address risk alignment, support regulatory reporting and identify growth opportunities in emerging low-carbon markets.

The tool combines public and proprietary data, helping insurers understand where clients stand today and how they’re progressing across key dimensions: compliance, risk management and growth. A view especially valuable for sectors facing heightened scrutiny and transition complexity amidst an evolving energy landscape.

“Insurers are under increasing pressure to understand and report on transition risk for their clients, but the data is often fragmented and difficult to interpret,” said Liz Henderson, Head of Climate Risk Advisory at Aon. “The TPI Portfolio and its corresponding data has been strategically designed to be a common language for transition risk—one that supports collaboration and clarity across the insurance value chain.”

Addressing a Growing Challenge

The global energy system is undergoing rapid transformation with a convergence of climate reporting frameworks, geopolitical instability and economic competitiveness accelerating a shift toward cleaner and more resilient energy models. Insurers play a pivotal role in this transition with their ability to assess and transfer risk, allowing for critical scaling of emerging technologies such as hydrogen, battery energy storage and carbon capture.

Aon’s Transition Performance Index Portfolio enables insurers to meet the growing demand for insurance capacity in these areas by eliminating common barriers to success, including inconsistent or sparsely available data, lack of resources and complexity of integrating this insight into decision making. By leveraging these insights, insurance companies can identify emerging risk patterns and customer needs, fueling the development of innovative products that are both timely and market-responsive.

“Those taking early steps toward technologies and sectors that support the net-zero transition are positioned to lead,” said Wouter Bosschaart, Global Energy Transition and Climate Lead at Aon. “Just as insurers that built early capabilities in renewable energy are now shaping the market, TPI Portfolio helps identify and support those future-ready clients—unlocking opportunity where transition risk meets innovation.”

The TPI portfolio is a key component of Aon’s forthcoming Low-Carbon Transition Framework, a structured approach designed to help insurers navigate their sustainability journey. The seven-step guide includes actionable steps and recommendations to help define a transition strategy, utilizing the insights offered through TPI to assess current exposures, benchmark performance and identify growth opportunities.

Aon continues to expand its Climate Risk Advisory capabilities, helping clients shape better decisions via proactive strategy in an increasingly complex and fast-moving energy landscape, and a growing decarbonizing economy.
