Ethical Sourcing

Ethical sourcing has moved from a voluntary corporate responsibility commitment to a legally mandated element of public procurement across Europe. Legislation requiring due diligence on labour conditions, human rights, and environmental impacts throughout supply chains is now in force or coming into force in multiple European jurisdictions, and the EU's regulatory framework is setting a new baseline for what responsible sourcing means in practice.

What is Ethical Sourcing?

Ethical sourcing refers to a buyer's commitment to procure from suppliers that meet defined standards across a range of non-financial dimensions: fair and safe working conditions, prohibition of forced and child labour, respect for workers' rights to organise, environmental management, anti-corruption compliance, and responsible raw material sourcing.

In public procurement, ethical sourcing requirements are embedded through several mechanisms. Contract conditions may require suppliers to comply with applicable labour law, international labour standards (ILO core conventions), or sector-specific codes (such as the Ethical Trading Initiative Base Code). Selection questionnaires may ask suppliers to describe their supply chain due diligence processes. Evaluation criteria may award marks for strong ethical sourcing programmes.

The EU regulatory landscape for ethical sourcing is evolving rapidly. The EU Corporate Sustainability Due Diligence Directive (CSDDD), adopted in 2024, requires large companies to conduct human rights and environmental due diligence across their supply chains, with civil liability for failures. The EU Forced Labour Regulation prohibits placing goods made with forced labour on the EU market. Directive 2014/24/EU itself allows contracting authorities to exclude operators for breaches of applicable social or labour law obligations under Article 57(4)(a), and to set contract performance conditions relating to social and employment considerations under Article 70.

In the UK, ethical sourcing in public procurement is shaped by the Modern Slavery Act 2015, the UK Government Buying Standards, and the Procurement Act 2023, which introduces stronger provisions for considering labour market conduct in supplier assessment. The UK's Social Value Act 2012 also incentivises buyers to seek social and ethical outcomes through procurement.

Why it matters for bidders

Suppliers tendering for public contracts across Europe face growing expectations around ethical sourcing documentation. A credible ethical sourcing programme includes: a supplier code of conduct that sets minimum standards for subcontractors; a risk-based supply chain mapping process that identifies where labour and environmental risks are concentrated; third-party audit or certification (such as SA8000, Fair Trade, or sector-specific standards) for high-risk supply chain tiers; and a process for addressing non-conformances when they are identified.

Suppliers who cannot demonstrate active supply chain management on these dimensions face increasing exclusion risk, reputational damage, and exposure to civil liability under incoming due diligence legislation. Conversely, suppliers with strong, evidenced ethical sourcing programmes can use them to differentiate in competitive tenders where social and environmental criteria are scored.

Example

A clothing manufacturer submits a bid for a European university's student workwear contract. The university's selection questionnaire asks for evidence of the company's supply chain due diligence process. The supplier provides its supplier code of conduct, a map of its garment manufacturing supply chain including tier-2 fabric suppliers, and audit reports from two independent auditors covering its primary manufacturing facilities in Turkey and Portugal. It also provides a description of its corrective action process when audit non-conformances are identified. The university's evaluation team scores the supplier's response as strong, contributing to a high overall selection score.

Frequently Asked Questions

What supply chain tiers must ethical sourcing cover?

At minimum, tier-1 (direct) suppliers. Leading practice extends to tier-2 (suppliers' suppliers) and, for high-risk commodities, deeper. The EU CSDDD requires due diligence across the entire chain of activities, though the depth of obligation is proportionate to the size of the company and the level of risk identified. For public procurement purposes, the depth of scrutiny expected should be proportionate to the contract's risk profile.

Can a contracting authority reject a bid for poor ethical sourcing performance?

Yes, in two ways. Under Article 57(4)(a) of Directive 2014/24/EU, an operator can be excluded for breach of applicable social or labour law obligations. Where ethical sourcing is included as an award criterion, poor scoring on that criterion will affect the overall score. In the UK, the Procurement Act 2023 provides grounds for exclusion based on labour market misconduct.

How do third-party certifications factor into ethical sourcing assessments?

Certifications such as SA8000, ISO 45001 (occupational health and safety), or Fair Trade certification provide third-party assurance that a supplier meets defined standards. Contracting authorities may accept certifications as evidence of compliance with specific requirements, though they typically cannot require a specific certificate without accepting equivalent evidence. Certifications are useful but not a substitute for ongoing supply chain monitoring.
