Which standard supports organizations in acting ethically and sustainably?

The correct choice is ISO 20400:2017, as this standard specifically focuses on sustainable procurement. It provides guidance for organizations on integrating sustainability into the procurement process, encouraging practices that consider economic, environmental, and social impacts. By implementing this standard, organizations can ensure their purchasing decisions align with ethical practices and promote sustainability throughout their supply chains.

ISO 20400 emphasizes principles of responsible sourcing, enabling organizations to apply sustainability concepts in a systematic manner. This helps to foster long-term stakeholder relationships and contributes to the wider achievement of sustainable development goals.

In contrast, ISO 9001:2015 is centered around quality management systems, focusing on meeting customer expectations and consistently delivering quality products and services without a direct emphasis on sustainability. ISO 14001:2015, while related to environmental management, addresses broader environmental performance rather than the specific practices of procurement. Lastly, ISO 45001:2018 relates to occupational health and safety management systems, prioritizing worker safety rather than sustainability in sourcing or procurement processes.
