Successfully Implementing ESG in Insurance Industry

The insurance industry is under immense pressure to implement ESG. Regulatory requirements, reporting obligations, new stakeholder expectations, and the adaptation of products, processes, and responsibilities are driving this transformation at a rapid pace. Many insurers are working hard to implement sustainable insurance both organizationally and technically. Yet it is precisely in this phase that a crucial challenge emerges: ESG is not merely a technical issue, but a company-wide transformation process. That is precisely why a purely technical ESG approach is not enough. That’s what the “Sustainable Insurance” study by Union Investment and RheinMain University of Applied Sciences, in cooperation with viadoo GmbH, already made clear.

1. ESG in insurance is a leadership &communication issue

As soon as sustainability becomes part of daily work, it is no longer just about guidelines, reports, and governance. It’s about priorities, routines, responsibilities, and behaviors. Employees must understand new requirements, translate them into their work, and incorporate them permanently. Leaders must provide guidance, explain decisions, and make conflicting goals manageable. Communication managers must turn complex regulations into accessible internal communication.

This is precisely where sustainable insurance becomes a change initiative.

After all, transformations rarely fail because there are no technical concepts at all. They stall because the organization does not support them uniformly, because leadership is not aligned consistently enough, or because social and emotional dynamics are underestimated. Anyone who wants to embed ESG in the company must therefore not only define measures but also organize acceptance, participation, and the ability to implement them.

2. Social & emotional aspects still underestimated

The study suggests that it is precisely this cross-functional level that is not yet sufficiently in focus in parts of the industry. This applies above all to the role of leadership, communication, and participation.

A real-world example is particularly revealing in this context: At Union Investment, 336 measures have been implemented in-house over the past ten years. Another 50 are set to be added by 2025, as Frank Jakob, Head of Sustainability Management, reported. Some of these measures involve aligning insurance products – such as property and casualty, life, and investment – with ESG criteria. However, many measures also entail changes in habits and corporate culture.

This is precisely where the real management challenge lies. Processes can be adapted. Structures can be defined. But mindsets and culture do not change at the push of a button. This requires systematic participation, clear leadership communication, and professional change leadership.

3. Intrinsic motivation alone is not enough

In many insurance companies, there seems to be a lingering hope that the topic of sustainability, due to its social relevance, will mobilize sufficient energy on its own. In fact, support for sustainability goals is often higher than for other areas of transformation, such as digitalization.

Yet in practice, the moment ESG requires teams and individuals to permanently change their behavior in their daily work, the driving force of intrinsic motivation quickly diminishes. This is not surprising. After all, agreeing to a goal is not the same as consistently changing behavior under time pressure, conflicting priorities, and a heavy workload.

Especially in insurance companies, with their complex structures, specialized logic, and regulatory obligations, good intentions alone are not enough. What is needed is a resilient change architecture—a systematic framework for how changes are explained, prioritized, managed, communicated, and embedded in daily life.

4. What executives should take away from this

For board members, this means: ESG is not an isolated sustainability or compliance project, but a strategic change process that impacts leadership, organization, and culture.

For ESG leaders, this means: Technical excellence is not enough if implementation is not made compatible across the entire company.

For communications decision-makers, this means: Internal communication is not merely a supporting medium for ESG transformation, but a key success factor. It provides direction, translates complexity, and makes change manageable.

This leads to three key areas of action:

1. Embed ESG company-wide instead of isolating it functionally
   Sustainability must be made accessible across all departments. If ESG is only “managed” in specialized departments, the ability to implement it at the operational level is often lacking.
2. Visibly link leadership and governance to the transformation
   Sustainability requires clarity in roles, decisions, responsibilities, and priorities. This can also take the form of a sustainability steering committee or the role of a Chief Sustainability Officer (CSO).
3. Systematically establish communication and engagement
   Employees must understand what is changing and why, what this means for their department, and how they themselves can contribute. Without this explanation, ESG often remains abstract.

5. How viadoo can support insurers

This is precisely where the added value of a professionally designed transformation approach lies. Introducing ESG into insurance companies requires not only expertise in requirements and processes but also experience in how change actually succeeds within organizations.

viadoo GmbH supports insurers in combining the technical aspects of ESG transformation with the human side of change. This includes questions such as:

• How can ESG be effectively embedded in leadership and the organization?
• How can employees be systematically involved in the transformation?
• How should internal communication be structured so that regulatory requirements become actionable guidance?
• How can a consistent change architecture emerge from many individual measures?

Precisely because sustainable insurance remains a moving target, this combination of technical implementation, communication, and change leadership is crucial. Insurers that want to not only comply with ESG but also embed it sustainably within the company need more than regulatory know-how. They need an approach that brings the organization along with it.

6. Conclusion

The insurance industry is working with great dedication on the sustainable insurance transformation. Large companies are already further along, while smaller firms are often still in the early stages. But regardless of maturity level, one thing is clear: ESG will only have a lasting impact if, in addition to processes and reporting, leadership, communication, engagement, and culture are also professionally designed.

This is precisely where untapped potential still lies for many insurers.
