Double Materiality Assessment (DMA)

Are you preparing for the Corporate Sustainability Reporting Directive (CSRD) and need to conduct a Double Materiality Assessment? Or do you need to understand which ESG topics are most relevant for your company?

At TOSCA, we help your organization identify its most material ESG topics — from both a financial as well as an impact perspective — in full alignment with CSRD and ESRS standards.

What is a Double Materiality Assessment?

A DMA identifies: 

• Topics where your business impacts people and the environment (impact materiality) 
• Topics that materially affect your company’s financial performance which are risks and opportunities (financial materiality) 

These insights form the basis for your sustainability strategy, CSRD/ESRS reporting obligations, policies, and targets. 

Our Approach: 6 Steps to Strategic Focus 

Our structured, hands-on approach aligns fully with the CSRD and ESRS requirements: 

1. Set-up 
   Form a cross-functional team, define sustainability ambition, and conduct a stakeholder analysis (who to engage for impact vs. financial materiality) and a value chain analysis 
2. Identification 
   Build a longlist of potential topics based on CSRD/ESRS standards, sector benchmarks, media, peers, and your value chain. 
3. Assessment 
   Cluster and define IROs (Impacts, Risks & Opportunities), assess relevance across your operations and value chain, and connect to stakeholder interests. 
4. Prioritization 
   Score IROs based on scale, likelihood, severity, and recoverability. Outcome: a draft materiality matrix. 
5. Validation 
   Conduct internal and external stakeholder engagement (interviews, workshops, surveys) and align with leadership to finalize the material topics. 
6. Documentation 
   Deliver a complete process description ready for external assurance, meeting CSRD and ESRS audit expectations. 

You'll receive:  

• A visualized materiality matrix 
• A prioritized list of material ESG topics 
• Full documentation aligned with CSRD requirements 
• Input for sustainability strategy, actions, goals, and metrics 
• Stakeholder engagement mapped to regulatory expectations 

Timeline: 3–6 months 

Depending on the complexity of your organization, ambition level, and available data, we tailor the timeline accordingly. 

Our DMA approach is ideal for:

• Companies who want to understand their priority ESG topics as input for reporting and strategy 
• Companies with CSRD obligations  
• Organizations wanting to embed sustainability strategically
