In an era where environmental, social and governance (ESG) considerations are increasingly pivotal in organisational decision-making and strategy design, the importance of stakeholder engagement cannot be overstated. An in-depth understanding of stakeholder priorities and the ESG factors that drive business success is necessary for any organisation looking to take its approach from ESG box-ticking to something that leads to genuine social and environmental impact. Materiality assessments are a valuable, multi-faceted tool that support organisations in strengthening their ESG strategies and reporting, in part by enabling meaningful stakeholder engagement.
