Sustainable procurement: principles and best practices

What is sustainable procurement?

Sustainable procurement means embedding environmental, social and ethical criteria into the sourcing process. The goal is to ensure economic performance does not come at the expense of human rights, the environment or ethics. It covers the whole purchasing cycle: need definition, supplier selection, negotiation, execution and performance evaluation.

At the heart of an ESG policy, sustainable procurement extends a company's social responsibility beyond its direct perimeter: it also engages its value chain. It is a concrete way to anchor responsibility in daily practice.

The core principles of sustainable procurement

1. Governance and ethics

Sustainable procurement needs clear steering. The procurement department or a dedicated committee must formalize a policy setting commitments, scope and control levers. A supplier code of conduct completes this base: it defines minimum requirements on ethics, human rights and regulatory compliance.

2. Environment and energy performance

Environmental criteria aim to reduce the ecological impact of purchased goods and services: energy and water use, life-cycle GHG emissions, waste management, repairability and recyclability. Favoring suppliers with an environmental management system (such as ISO 14001 or strong ESG practices) is effective.

3. Social responsibility

Sustainable procurement means promoting safe, fair working conditions across the supply chain: selecting partners that respect fundamental rights, diversity, equal opportunity and social dialogue.

4. Shared value creation

Rather than mere control, a partnership logic is preferred: encouraging suppliers to progress and innovate toward more sustainability. Continuous-improvement and co-development policies deliver mutual gains.

Embedding sustainable procurement into ESG strategy

Integration goes beyond contractual clauses: it relies on a structured approach assessed in any CSR assessment.

1. Policy and governance: appoint an owner, set objectives and have the policy approved by management.
2. Supplier code of conduct: a document partners sign, setting ethical and environmental foundations.
3. Evaluation and monitoring: key indicators such as the share of CSR-assessed suppliers, the percentage of code signatories, the number of audits.
4. Continuous improvement: annual policy review and integration of new regulatory issues (e.g. CSRD).

Assessing and selecting responsible suppliers

Evaluation relies on multi-criteria analysis: regulatory compliance, certifications (ISO, environmental labels), social practices and CSR performance. Audits or self-assessments make the selection objective and track progress over time.

For an SME, a gradual approach is often most effective: start with strategic suppliers, prioritize critical risks (raw materials, offshore subcontracting), then expand progressively.

Tracking and measuring sustainable procurement performance

The effectiveness of a sustainable procurement policy is measured through KPIs built into ESG reporting:

• % of suppliers assessed or audited on CSR practices;
• code-of-conduct signature rate;
• % of purchases from short supply chains or certified products;
• emissions savings (tCO₂e) from material substitution or responsible logistics.

Regular monitoring aligns purchasing with the company's overall climate and social objectives and ensures the transparency required by the ESRS and CSRD frameworks.

Best practices to sustain the approach

• Train buyers on ESG issues to strengthen their strategic role.
• Embed CSR criteria from the need-definition stage: eco-design, durability, reuse.
• Collaborate with suppliers: sharing best practices, improvement plans, joint innovation.
• Leverage CSR audits to identify concrete progress and showcase wins in reporting.

This creates a virtuous circle: lower risk, better compliance, stronger image and shared value creation.
