Streamlining CSRD Double Materiality Assessments

Onye Dike
Updated by Onye Dike on July 6th, 2026
Materiality Master is a software platform designed to help organisations conduct CSRD-compliant double materiality assessments in accordance with the European Sustainability Reporting Standards (ESRS). It is aimed at companies, NGOs, ESG consultants, and sustainability teams that need to identify, assess, and document sustainability impacts, risks, and opportunities (IROs). Rather than functioning as a broad ESG management platform, Materiality Master focuses specifically on the double materiality process, guiding users through a structured workflow from stakeholder analysis to ESRS datapoint mapping. By automating many repetitive tasks, it helps reduce the administrative effort involved in preparing for CSRD reporting.

Core Features

Materiality Master follows the four-step process recommended for double materiality assessments: identifying stakeholders, identifying impacts, risks and opportunities (IROs), assessing their materiality, and mapping the results to ESRS disclosure requirements. Its principal capabilities include:

  • Stakeholder Analysis – Helps organisations identify, prioritise, and document stakeholders and their relationship to sustainability topics.

  • IRO Assessment – Supports the identification and evaluation of impacts, risks, and opportunities using structured financial and impact materiality scoring.

  • Automatic Materiality Matrix – Generates an interactive materiality matrix from assessment results, providing a visual summary of material topics.

  • ESRS Datapoints Mapping – Automatically maps material topics to more than 1,100 ESRS datapoints, with export to Excel and PDF.

  • AI-Assisted Guidance – Uses AI to help generate descriptions and justifications for IROs while leaving final decisions to the user.

  • Audit Trail and Access Management – Maintains documentation for audit purposes and enables organisations to manage user permissions during the assessment process.
