Sustainability in Supply Chains and Procurement: A Guide to ISO 20400

Sustainability, which has become increasingly important in recent years, is now a key consideration for organizations both in their operations and throughout their supply chains. The environmental, social, and economic impacts of purchased products and services can directly or indirectly affect organizations’ sustainability objectives, risks, and relationships with stakeholders.

As the impacts of purchased products across different areas can influence organizations’ sustainability objectives, procurement processes play an important role in integrating sustainability throughout the supply chain.

ISO 20400 provides international guidance on how sustainability can be integrated into supply chain and procurement processes.

What Is Sustainable Procurement?

Sustainable procurement is an approach that enables organizations to conduct their procurement processes while considering environmental, social, and economic impacts.

This approach supports the assessment of a product or service’s impacts from a long-term and broader perspective. Factors such as potential impacts throughout the life cycle of products and services, suppliers’ working conditions and ethical business practices, and environmental impacts are taken into account in procurement decisions.

Through a sustainable procurement approach, the life cycle of products and services is considered from a broader perspective, significant risks and opportunities are identified based on organizational needs, and sustainability is integrated into operational processes as a long-term approach.

What Is ISO 20400?

ISO 20400:2017 is an international standard that provides organizations with guidance on integrating sustainable procurement into their activities.

Within the framework of ISO 20400, organizations assess the risks and opportunities associated with procurement activities, determine their priorities, and improve their processes by monitoring performance. In this way, sustainability is integrated into the organization’s procurement approach.

ISO 20400 does not contain requirements intended for certification. Instead, it provides a guidance framework that organizations can apply according to their structure, activities, and priorities.

The Relationship Between ISO 20400 and ISO 26000

While ISO 26000 provides guidance to organizations on social responsibility, ISO 20400 focuses specifically on how sustainability can be integrated into procurement activities.

ISO 20400 draws on the social responsibility principles addressed in ISO 26000. Topics covered by ISO 26000, such as human rights, transparency, fair operating practices, and consumer issues, also provide a basis for evaluating procurement decisions from a sustainability perspective.

Neither standard is a requirements standard intended for certification. While ISO 26000 provides broader guidance on social responsibility, ISO 20400 helps organizations apply this approach specifically to procurement activities.

Sustainability in Supplier Selection and Evaluation

Suppliers are among the factors that can influence an organization’s sustainability performance. To achieve their sustainability objectives, organizations should also evaluate their suppliers in areas such as environmental impacts, ethical business practices and working conditions, natural resource use, and human rights.

Ensuring sustainability in procurement does not require every supplier to be evaluated against the same criteria. Organizations can strengthen sustainability by assessing the issues that are most significant to their activities, establishing relevant priorities, identifying areas for development, and implementing improvements accordingly.

Benefits of the ISO 20400 Approach for Organizations

The ISO 20400 approach can provide organizations with guidance on:

• Integrating sustainability into procurement strategies,

• Assessing risks and opportunities within the supply chain more systematically,

• Considering environmental, social, and economic factors together in procurement processes,

• Taking stakeholder expectations into account.

By applying ISO 20400, organizations can assess their procurement processes from a sustainability perspective and move beyond viewing procurement solely as an operational activity that meets organizational needs. In this way, procurement can become an important tool for supporting broader sustainability objectives.
