How do you create value through sustainability?


Materiality Assessment Tool

The MAT is an online survey tool that applies a structured and robust metric to materiality assessment, allowing you to easily identify your organisation’s most significant sustainability impacts, based upon stakeholder feedback.  

Developed in collaboration with sustainability psychologist Tim Cotter, from Awake, the MAT will greatly simplify your materiality assessment process. 

Gauge where improvements in your organisation’s sustainability impact can be made with the outcomes of the MAT assessment and improve your sustainability strategy year on year. 

The MAT:

  • Identifies the sustainability issues that employees and other stakeholder groups believe are most material to the organisation and also consider important to themselves
  • Measures stakeholder perception of the organisation’s sustainability performance, weighted against the importance
  • Provides a robust quantitative and qualitative analysis of performance that can be used to inform internal and external sustainability programs and strategy
  • Is a cost and resource efficient tool that will save you time and money when approaching your materiality assessment when compared with using focus groups and interviews

In 2017, Tassal completed its first online materiality assessment using the Materiality Assessment Tool (MAT). The assessment was customised specifically for our business and provided an easy format for participants to complete online. The survey results were presented in a comprehensive report that identified sustainability issues that were most significant and important, allowing us to understand where performance improvements were required, thereby influencing sustainability strategy and enabling meaningful reporting. Using the MAT provided us with a robust basis for the identification of material topics, resulting in a more focused 2017 Sustainability Report.”
