Sustainability materiality assessment process for issuers

Short answer

A materiality assessment determines which sustainability issues are important enough to report. The process: identify issues, engage stakeholders, assess and prioritize, then validate. It's important to distinguish impact materiality (GRI, the company's outward effect) and financial materiality (IFRS/PSPK, issues' effect on company value); together they are called double materiality.
