SustainabilityAccountingStandards Board

SASB Standards guide companies to disclose relevant information to investors based on their industry sector; SASB provide 77 industry sector standards identifying the sustainability related risk
and opportunities most likely to impact an entity’s cash flows, access to capital and cost of capital over the short, medium or long term. As of 2022 the International Standards Board (ISSB) of theIFRS Foundation assumed responsibility for the SASB standards. In future, we will align with ISSB’s sustainability reporting standards.
