What is ISO 20400?
ISO 20400:2017 is an international standard designed to help organizations systematically implement sustainability principles in their supply chains.
This standard ensures that purchasing decisions are evaluated not only in terms of cost and quality, but also in terms of environmental, social, ethical, and economic impacts.
ISO 20400 provides guidance to organizations on developing sustainable purchasing policies, monitoring supplier performance, and ethical supply chain management.
