Sustainability
Report 2025

Welcome to the Sustainability Report 2025

Sustainability is an integral part of Interroll’s long-term value creation. It takes into account energy efficiency, reliable and compliant supply chains, resilient operations, and transparent product data. These are increasingly relevant for customer decisions, regulatory market access, and long-term margin quality. 

In 2025, we defined a new Sustainability Framework structured around People, Planet, and Product. This framework links our business model and global value chain to environmental, social, and governance (ESG) topics and supports a clear focus on what is most relevant for Interroll. Within the framework, we define clear priorities and accountability, and create consistency across the Group.

2025 was characterized by a changing regulatory environment in Europe. These developments affect both Interroll and our customers by influencing, for example, purchasing decisions and product specifications. This reinforces the need for integrating sustainability into our core business. At the same time, Interroll underwent a strategic transition at Group level. In parallel with the appointment of a new Chief Executive Officer and the refinement of our corporate strategy, we also reviewed our sustainability strategy.

The Sustainability Strategy 2030 focuses on the areas where we can create the greatest impact, aligning our efforts with what matters most for the business and for our customers.

During the year, we strengthened the quality and reliability of our non-financial information. We improved our reporting processes and refined our greenhouse gas accounting methodologies. These efforts ensure that sustainability-related decisions are based on robust and comparable data. The improvements required changes and corrections to previously published data for 2024.

We also refined our double materiality assessment, focusing on impacts, risks, and opportunities across the value chain. The result is a focused set of nine material topics that now serves as the basis for strategic prioritization, target setting, and disclosure.

Looking ahead, our priorities are clear. We will continue to improve data quality and transparency, and strengthen regulatory readiness. We will accelerate measures to reduce Scope 1, Scope 2, and in particular Scope 3 emissions, our main lever for decarbonization.

Progress in Scope 3 depends largely on product design, energy efficiency during product use, and the resilience of our supply chain. We therefore systematically enhance the sustainability characteristics of our products over their life cycle and strengthen engagement across the value chain. Furthermore, we are rolling out the Sustainability Framework globally and strengthening sustainability awareness across the organization.
