One key concept reappears when talking about sustainability and ESG — and reporting in particular: double materiality assessment, often abbreviated DMA.
But what does it really cover, where do you start, and why is it a valuable tool?
In this article we explain the concept and why a DMA is indispensable for companies that want to work purposefully and strategically with sustainability and ESG.
What is a DMA?
A DMA is a methodology that helps companies identify and prioritize what is essential within the three ESG pillars: Environment, Social and Governance. The result is a well-founded and unified basis for your sustainability efforts — both in terms of strategy, reporting and execution.
“Double” materiality means that the assessment is based on two perspectives, which together give the full picture:
Significance of impact (from the inside out): How the company's activities and value chain affect people, the environment and nature.
Example: A company that emits greenhouse gases negatively affects the climate.
Financial materiality (from the outside and in): How external ESG factors can create financial risks or opportunities for the company.
Example: A new CO₂ tax that increases costs and thus poses a financial risk.
An item is considered significant if it is assessed as important from either an impact or financial perspective, or both. The DMA helps you identify the areas that matter most to the world around you and to your business.
DMA approaches
A DMA can be organized in several ways. Where the original European Sustainability Standards (ESRS) laid out a *bottom up* approach, the latest drafts of revised standards open up the fact that companies can now choose between both a top down and a bottom up method. Both approaches lead to the same result, but the path to it varies.
A bottom up approach is based on your concrete impacts, risks and opportunities related to sustainability. These are gathered into overall sustainability topics that form your focus areas. This method provides a detailed picture of the reality of your business.
A top down approach starts with a number of overarching sustainability topics (e.g. from ESRS topic lists or company-specific matters). When a topic is significantly assessed, one delves deeper into the level of impacts, risks and opportunities. The advantage is that the process becomes more manageable because you zoom in gradually and only on relevant areas.
The choice between the two approaches depends on your needs and resources. Whichever method you choose, the goal is the same: to provide a solid and credible basis for identifying the essential topics that will underpin your ESG work and reporting.
Why is the DMA valuable?
A DMA is more than a reporting requirement. It is best practice and a strategic tool. It helps you focus on areas where you can make a real difference and where efforts are also business-critical.
With the DMA, you get a solid foundation to prioritize the areas where you have the greatest impact on people and the environment, and which at the same time pose the most significant risks or opportunities for your business. You will be given a starting point to drive improvements in practice.
At the same time, the process supports dialogue with stakeholders. Although stakeholder involvement is not a direct requirement, their perspectives must be included. Therefore, the DMA helps you reflect both the organization's own priorities and the expectations that exist in the world around you. By clarifying why certain topics are prioritized, the DMA enhances the transparency of your communications. It increases credibility with customers, employees, investors and partners.
For companies covered by CSRD, the DMA is a legal requirement. But even for those not yet directly subject to the rules, it is an investment in the future. The DMA lays the foundation for robust ESG reporting and strategy that can withstand regulatory requirements, market expectations and changing conditions.
Conclusion
A double materiality assessment is far more than a tick in a reporting box. It is a compass that helps you focus and create real value for both the business and the world around you. By working in a structured way with DMA, you not only get a handle on reporting requirements and best practices, but also a tool that can support strategic decisions, strengthen relationships with your stakeholders and create long-term competitiveness.
