The role of ESG data in modern insurance underwriting

Insurance firms have begun implementing environmental, social and governance (ESG) data into their offerings amidst a swell of pressure from stakeholders. This data is transforming underwriting profitability, enabling better risk assessments, product innovation, and regulatory compliance. 

Insurance firms have begun implementing environmental, social and governance (ESG) data into their offerings amidst a swell of pressure from stakeholders. This data is transforming underwriting profitability, enabling better risk assessments, product innovation, and regulatory compliance. 

While risks come with many facets, the ESG dimension has only recently emerged as a nascent but growing focus within the sector, and it is set to be a critical factor in risk assessment.

Property and Casualty (P&C) insurers, for example, have even expanded their scope to include the collection and analysis of ESG-related data.

By examining the ESG performance of thousands of properties worldwide, these ratings shed light on the ESG risks tied to the estate under review, offering a clearer picture of their broader sustainability profile.

FinTech Global‘s Harry Slade sat down with a pair of industry experts to discuss the role of ESG data in modern insurance underwriting.

Keeping up with the trends

In this era of heightened scrutiny, ESG considerations are no longer confined to the boardrooms of regulators or the demands of investors.

Employees, business partners, agents, and end customers are increasingly vocal about their expectations, driving a shift in priorities for insurers.

This diverse group of stakeholders, with their varying perspectives and spheres of influence, shares a common thread: the demand for accountability, transparency, and sustainable practices.

As these expectations grow, insurers must grapple with their role not just as risk managers, but as stewards of societal and environmental resilience.

This sentiment was shared by Paul Richmond, Head of Customer Success at Novidea UK, an insurance distribution lifecycle platform, who explained that companies must enhance their understanding of sustainability risks and their financial consequences, particularly when developing and evaluating long-term strategies.

“The London market, renowned for covering all types of risks, plays a pivotal role in supporting innovative products that address ESG-related risks,” said Richmond. “To enhance its awareness of sustainability risks and their financial implications, particularly in the context of long-term models, it is essential to improve access to data and ensure it is easily consumable.”

This is underlined in the numbers. According to a PwC survey, 85% of all global insurers believe that ESG will impact their business in all facets. Investments was identified as the single largest area of impact (91%), followed by risk and internal audit (90%) and underwriting (88%).

With this in mind, it is no surprise that ESG data is now being readily used to bolster the cyber underwriting landscape.

Melanie Hayes, COO and co-founder of KYND, a UK-based cyber risk management firm, explained, “ESG data is increasingly shaping the future of insurance, especially in cyber underwriting, by redefining how insurers assess and price risks. Beyond traditional metrics, ESG insights illuminate systemic vulnerabilities – such as weak governance frameworks or unsustainable digital practices – that in today’s digital-first corporate environment elevate cyber risk exposure.”

All this means that adopting ESG principles is more than a compliance exercise for insurers—it’s a strategic imperative that enhances their ability to differentiate risks while positioning them as pivotal players in building sustainable, resilient ecosystems.

By integrating ESG into their operations and underwriting decisions, insurers can foster trust among stakeholders, align seamlessly with evolving regulatory frameworks, and assert their leadership in a world where risks are becoming more complex and interconnected.

Bolstering underwriting procedures

In the insurance realm, improving your underwriting efficiency is a proven way to boost your overall competitiveness. As a result, data-driven solutions have been implemented on an international scale, with technologies such as AI, Machine Learning, and Internet of Things underpinning this transformation.

ESG data is the next evolution in this move, with its impact likely to redefine how insurers assess and price risks.

“As cyber risk management experts, at KYND we believe that incorporating ESG factors into cyber underwriting can improve risk assessment by helping uncover nuanced vulnerabilities often overlooked in traditional models,” explained Hayes.

Corporate governance practices, including board oversight of cybersecurity and management of third-party risks, serve as indicators of an organisation’s structural resilience.

Social factors, such as employee awareness of cybersecurity threats and adherence to digital ethics, shed light on behavioural risk factors.

Meanwhile, environmental aspects, like the adoption of sustainable technology and robust cyber risk management, reflect an organisation’s readiness to handle incidents that could impact their environmental responsibilities.

Hayes explained, “Viewing ESG as a strategic framework, rather than merely a data set, enhances underwriting accuracy, aligns with shifting client priorities, and positions cyber insurers as proactive champions of resilience and sustainability in a connected world.”

Challenges with implementation 

Despite this, a Capgemini report reveals that less than half of property and casualty insurers have integrated ESG scores into their processes, highlighting slow adoption in sustainable underwriting.

Integrating ESG data into underwriting models presents insurers with a dual challenge: data immaturity and technological constraints. ESG data often originates from varied, uncoordinated sources, making standardisation for accuracy and sharing particularly difficult.

Without unified platforms, data risks remaining in silos, mirroring inefficient systems of “offline spreadsheets and manually processed reinsurance schedules,” according to Richmond.

This opinion was shared with Hayes, who added, “The first and foremost challenge in integrating ESG data into cyber underwriting is the fragmentation and inconsistency of ESG data, which lacks standardised metrics, complicating meaningful comparisons across organisations.”

Addressing this requires technology providers to evolve their platforms to ingest and integrate new data effectively. Richmond warns that, “If not, data remains separate,” undermining the potential for ESG factors to shape underwriting practices.

The opportunity, however, is immense. The insurance market, a historical leader in innovation, can use ESG data to redefine risk management standards.

“It is critical that these challenges are overcome – as the insurance market is often at the forefront of innovation, and the analysis doesn’t just insure risks but sets the benchmark for what is acceptable. The insurance market has a huge opportunity to use ESG data and help shape better risk management of ESG factors within organisations, with the incentive to reduce premiums if certain ESG factors are met,” Richmond explained.

What to expect in 2025

By 2025, ESG data is expected to play a transformative role in shaping industries. Beyond assessing risks, it will drive ethical governance and sustainable practices, setting higher standards across sectors.

Insurers embracing this approach will appeal to ESG-conscious investors, highlighting their commitment to resilience and long-term sustainability in a rapidly evolving landscape.

This is sure to see ESG data incorporated into underwriting platforms, with enhanced analytics enabling more precise risk evaluations and fostering alignment with sustainability goals.

Hayes explained, “By intertwining ESG data with underwriting models, insurers will be positioned to lead the charge in embedding responsibility into the digital economy’s foundation.”

Firms that fail to follow this lead risk falling behind in an increasingly competitive market. As investors and clients prioritise sustainability, those who overlook this key metric will struggle to attract capital and maintain relevance, ultimately missing the opportunity to lead in a rapidly evolving landscape.

Embracing ESG will not just be a competitive edge—it will be a necessity for firms aiming to thrive in the future.
