What ethical sourcing and procurement actually involves

Ethical sourcing and procurement covers the policies, processes, and due diligence activities that ensure goods and services are obtained from suppliers that meet defined standards for labour conditions, human rights, environmental performance, and business conduct. For mid-market and enterprise companies, this spans supplier code of conduct development, risk-based supply chain mapping, supplier assessments and audits, remediation processes for non-conformances, and reporting under modern slavery legislation and emerging human rights due diligence requirements. It is increasingly governed by regulation, not just voluntary commitment.

Why it's harder in practice than it looks

Audit-based approaches are proving insufficient

Third-party social audits have been the dominant tool in ethical sourcing for two decades. They are increasingly recognised as inadequate: auditors have limited time on site, supplier relationships can incentivise concealment, and audits capture a snapshot rather than a systemic picture. Companies that rely solely on audit certificates to manage supply chain risk face genuine exposure when issues arise that were not, and could not have been, captured by an audit.

Tier 2 and 3 supply chain visibility is very limited for most companies

Human rights and environmental risks in global supply chains are often concentrated in raw material extraction and processing, typically at tier 2 or deeper. Most companies have robust processes for tier 1 suppliers and very little visibility beyond. Mapping deeper supply tiers requires supplier cooperation, specialist mapping tools, and supply chain transparency that many supply chain partners resist.

Emerging legislation raises the bar significantly

The EU Corporate Sustainability Due Diligence Directive (CSDDD), Germany's Supply Chain Due Diligence Act, and the French Duty of Vigilance Law all require companies to identify, prevent, and address adverse human rights and environmental impacts in their supply chains, going well beyond the reporting-focused approach of existing modern slavery legislation. Companies that have not built genuine due diligence capability face significant compliance work as these requirements come into force.

Supplier capacity and willingness to engage varies significantly

Small suppliers in high-risk sourcing regions often lack the management systems, documentation, or awareness to respond adequately to ethical sourcing requirements. Compliance demands without support create adversarial relationships; capacity-building takes time and resource but produces more sustainable outcomes.

What good looks like

A credible ethical sourcing programme includes a published supplier code of conduct with specific requirements for labour, environment, and business conduct, a risk-based supplier assessment process that differentiates by geography, category, and tier, a remediation process that supports suppliers in addressing identified issues rather than simply delisting them, a grievance mechanism accessible to workers in the supply chain, and disclosure aligned with Modern Slavery Act requirements and emerging CSDDD obligations. The most advanced programmes include worker voice mechanisms that verify audit findings directly with workers.

When to bring in external support

Supply chain risk mapping, supplier audit management, remediation programme design, and legislation compliance for CSDDD, German LkSG, or UK Modern Slavery Act all benefit from specialist support. Leafr's network includes ethical sourcing and human rights due diligence specialists who have built supply chain programmes for fashion, consumer goods, food and manufacturing clients including global enterprises such as Cargill and WD-40.

Frequently asked questions

What is ethical sourcing?

Ethical sourcing is the process of ensuring that goods and services are procured from suppliers that meet defined standards for human rights, labour conditions, environmental management, and business integrity. It applies throughout the supply chain, from raw material extraction through to finished product delivery, and is governed by a combination of voluntary commitments, customer requirements, and increasingly mandatory regulation.

What is the UK Modern Slavery Act and what does it require?

The Modern Slavery Act 2015 requires commercial organisations with an annual turnover of £36m or more that supply goods or services in the UK to publish an annual statement setting out the steps taken to ensure that modern slavery is not taking place in their business or supply chains. Statements must be approved by the board and signed by a director. A new mandatory reporting portal has increased enforcement visibility since 2021, and government guidance encourages increasingly substantive disclosures covering supply chain mapping, due diligence processes, and training.

What is the EU CSDDD and when does it apply?

The EU Corporate Sustainability Due Diligence Directive (CSDDD) requires large EU companies and certain non-EU companies with significant EU turnover to conduct human rights and environmental due diligence across their own operations and value chains, take action to address identified adverse impacts, and report on their due diligence processes. It phased in for the largest companies from 2027. Unlike Modern Slavery Act reporting, CSDDD requires genuine due diligence processes and remediation, not just disclosure of what has been done.

What is the difference between a supplier audit and supplier due diligence?

A supplier audit is a point-in-time assessment, typically conducted by a third party, that evaluates a supplier's compliance with specific standards at the time of the visit. Due diligence is a continuous process of identifying, assessing, preventing, mitigating, and remediating adverse human rights and environmental impacts in the supply chain. Due diligence is broader, more systematic, and ongoing; audits are one tool within a due diligence programme but cannot substitute for the whole process.

How should companies prioritise their supply chain due diligence?

Risk-based prioritisation should focus on the combination of likelihood of adverse impact (based on geography, commodity type, and tier) and severity of potential impact (based on the nature of the human rights or environmental issues at stake). High-risk categories typically include garments from South and South-East Asia, electronics from areas with mineral sourcing concerns, and food commodities from regions with known labour rights issues. Mapping spend against risk categories provides the foundation for a proportionate due diligence approach.
