Identify which sustainability topics are material
Double materiality analysis
Double materiality assessment – the first step toward sustainability reporting
A double materiality assessment is a key first step for companies preparing to report under CSRD or VSME. The assessment helps identify which sustainability topics are most relevant to the business – both in terms of financial impact and the company’s impact on climate, environment, and society.
At Aider, we support companies with a structured materiality assessment that provides a clear foundation for sustainability reporting, strategy, and prioritization.

What is a double materiality assessment?
A double materiality assessment evaluates which sustainability topics are material to a company from two perspectives:
Impact perspective
How the company affects climate, environment, people, and society. This includes factors such as climate impact, resource use, and human rights.
Financial risk perspective
How sustainability factors affect the company’s financial performance, risk exposure, and future opportunities.
Together, these perspectives provide a comprehensive view of which sustainability topics the company must report on under CSRD or VSME.
A thorough materiality assessment makes it easier to prioritize effectively and focus on the issues that truly matter – both for the business and for society.
Aider’s advisors have developed a structured methodology for double materiality assessments, based on EU guidelines and the frameworks underpinning CSRD and the EU Taxonomy.

What needs to be in place before the analysis?
To carry out a robust double materiality assessment, the company must have a clear understanding of how it impacts its surroundings.
This is particularly important in the following areas:
Climate impact
The company’s climate impact must be mapped through a climate accounting process that captures emissions across both operations and the value chain.
Human rights in the value chain
The company must have an overview of risks related to human rights within its own operations and across the supply chain, including through due diligence assessments in line with the Transparency Act.
If these elements are not already in place, Aider can support you with both climate accounting and due diligence assessments as part of the preparation for the materiality analysis.
A materiality assessment helps your business to
Prioritize the right sustainability topics
Meet the requirements of CSRD or VSME
Identify climate risks and opportunities
Understand its own climate impact
Strengthen the basis for management decision-making
