Macmahon is committed to improving its sustainability performance and reporting and in late 2020 interviewed its internal and external stakeholders to conduct a materiality assessment to inform its sustainability reporting. The materiality assessment has involved:

  • Identifying potential material topics based on a preliminary assessment of global sustainability reporting standards, peer company sustainability reporting , investor interests and priorities and ESG risks
  • Prioritising material topics by engaging with internal and external stakeholders (investors, brokers, clients and suppliers) to determine topics that most reflect Macmahon’s significant impacts and substantively influence the assessments and decisions of stakeholders, and
  • Validating material topics by assessing engagement results and determining material topics to be reported by Macmahon in its future sustainability reporting.

Material topics for Macmahon sustainability reporting

Material topics for Macmahon’s sustainability reporting are outlined in Table 1. It is possible that some identified material topics may not be able to be fully reported by Macmahon in its next sustainability report as it may take time to establish appropriate measures or indicators and gather data.
