Double Materiality Assessment – A Strategic Tool for All Businesses
A Strategic Tool for Everyone — Not Just for Companies Subject to Reporting Requirements
What is double materiality?
Double materiality is the principle that sustainability can be material to a company in two independent ways — and that both must be assessed.
Impact materiality concerns the company’s impact on the outside world. What actual or potential, positive or negative consequences does the business have for people, society, and nature — in its own operations and throughout the value chain? This is the ethical and societal perspective: what do we do to the world?
Financial materiality concerns what the outside world does to the company. Which sustainability-related factors — climate change, resource scarcity, regulatory pressure, social unrest — could affect the company’s earnings, costs, access to capital, or reputation? This is the strategic and commercial perspective: what does the world do to us?
A sustainability topic is material if it is material from at least one of these two perspectives. Some topics are material from both — for example, greenhouse gas emissions from an energy-intensive business, which both harm the climate (negative impact) and expose the company to carbon costs and regulatory risk (financial risk).
What are IROs?
The building blocks of a DMA are what are known as IROs — Impacts, Risks and Opportunities.
Impacts are the direct and indirect consequences a company has on people and the environment. They may be positive (jobs, local skills development, nature restoration) or negative (climate emissions, pressure on water resources, unsafe working conditions in the supply chain). They may be actual, ongoing consequences — or potential, future ones.
Risks are sustainability-related factors that may have negative financial consequences for the company. Physical climate risk (extreme weather, sea level rise) is an obvious example. But it may also include transition risks linked to new regulation, changing consumer behaviour, supply chain disruption, or reputational damage.
Opportunities are the positive financial effects that can arise when a company adapts to or leads the sustainability transition: demand for green products and services, cost savings through energy efficiency, access to green financing, and new markets.
A good DMA identifies and scores IROs systematically for each sustainability topic — and it is this process that makes the analysis strategically valuable, not just useful as a basis for reporting.
Why is DMA useful regardless of reporting obligations?
Let’s be specific. Here is what a DMA actually gives you:
Strategic context in a single framework. A DMA brings together insights that are usually fragmented across departments: value chain data from procurement, risk assessments from finance, stakeholder dialogue from communications, and regulatory monitoring from legal. Connected together, they create a holistic picture that is difficult to achieve in any other way.
Prioritisation that stands up in the boardroom. Not everything can be equally important. A DMA gives you a methodical, documented basis for saying: these are the three issues we are focusing our resources on — and this is why. That is an argument that holds up with owners, investors, and the board.
An early warning system for risk. Many of the sustainability risks that hit companies hardest are visible long in advance — if someone is looking for them. A DMA is specifically designed to capture those signals, from regulatory changes to climate impacts and social unrest in supply chains.
Value chain readiness. Pressure from large customers on supply chains is increasing rapidly. Companies subject to CSRD will request sustainability information from their suppliers. Those that already understand their own materiality profile can respond quickly and precisely — and appear as more attractive partners.
A foundation for future reporting. Whether it is VSME, CSRD, CDP, or investor questionnaires, they all build on the same basic question: what is material to your business? With a DMA in place, the rest of the reporting work becomes far more manageable.
What is included in a good DMA?
A materiality assessment is not a questionnaire sent to the management team and then summarised. Best practice is built on several layers of context that are connected systematically:
Understanding activities and the business model. A DMA must start with what the company actually does. Which activities generate revenue? Which inputs are critical? Which processes have the greatest exposure to sustainability-related issues?
Value chain analysis. Map the company’s activities in its own operations, upstream (raw materials, suppliers, transport), and downstream (distribution, use, disposal). The most significant IROs often sit outside your direct control — but still within your responsibility and risk profile.
Stakeholder dialogue. Who is affected by your company, and who influences it? Employees, local communities, customers, investors, authorities, civil society, and nature all have legitimate perspectives on what is material. Good stakeholder engagement is not just good practice — it is a source of insight you will not find in databases.
Global and sector-specific risk landscape. Which megatrends (climate change, demographic shifts, geopolitical tension, technological disruption) are relevant to your sector? Sector-specific analyses and global risk reports (such as the WEF’s Global Risks Report) provide context that elevates the analysis.
Organisational structure and ownership. Who in the organisation owns the different IROs? The link between material topics and concrete organisational responsibility is crucial to ensure the analysis does not simply sit unused. A DMA that is anchored in the board, management, and relevant functions is a DMA that is actually used.
Connections between topics. Sustainability topics are not isolated silos. Climate risk is linked to value chain exposure. Working conditions in the supply chain are linked to reputational risk and the Transparency Act. A strong DMA makes these connections visible and helps you see the system — not just the individual parts.
Scoring and prioritisation
Once the IROs have been identified, they must be assessed. For impact materiality, this concerns severity (scale, scope, irremediability) and likelihood. For financial materiality, it concerns the likelihood that the IRO will materialise and its potential financial effect.
The result is a prioritised list showing which topics fall above the threshold for materiality and therefore require action, reporting, and ongoing follow-up. Setting the threshold is an exercise in professional judgement. There is no single correct answer, but the method must be documented and justifiable.
Get started — regardless of size
A DMA does not need to be a major project to deliver value. For an SME, a first assessment can be carried out in just a few weeks with a structured approach, the right external guidance, and involvement from the right internal voices. The most important thing is to start with the right ambition: not as a compliance exercise, but as strategic understanding. What are we actually exposed to? What value and risk do we create in the world around us? And what does that mean for the road ahead?
The companies that have answers to these questions — documented and anchored — will be better prepared for what comes next, whatever the next wave of regulation may be called. Feel free to contact us for an initial conversation about what a materiality assessment could look like for your business.
