Supplier due diligence
What is supplier due diligence?
Supply chains are where many of the most significant sustainability risks and impacts sit, from labour and working conditions to environmental harm and climate-related exposure. Expectations are rising across customers, investors and regulators for organisations to demonstrate a structured, risk-based approach that goes beyond policy statements.
Our supplier due diligence service helps you identify, prioritise and address material social (human rights) and environmental risks across your value chain, using recognised frameworks such as the OECD Guidelines, ILO standards and the UN Guiding Principles.
We then embed due diligence into the way the business operates by integrating it into procurement and supplier management, strengthening governance and executive accountability and ensuring mitigation actions are clearly owned and tracked.
What this service covers.
Our supplier due diligence service includes segmentation and mapping of supplier networks, structured risk screening across human rights, environmental and carbon topics and materiality assessment across suppliers, commodities and geographies. We assess alignment with CSRD, CSDDD and modern slavery requirements and identify governance or documentation gaps that may expose the organisation to regulatory or reputational risk.
The service also includes development of prioritised mitigation plans with clear ownership, integration of escalation routes within procurement governance and production of board-ready reporting outputs that support executive oversight and defensible disclosure.
Value and benefits.
Our supplier due diligence service follows the OECD Guidelines, ILO standards and the UN Guiding Principles to establish a structured, risk-based process across your value chain.
It enables organisations to understand where material social (human rights) and environmental risks sit across suppliers, commodities and geographies, and to prioritise action in line with the severity and likelihood of impact. This creates clarity on where leverage exists and where focused intervention is required.
Due diligence is strengthened through the evaluation of existing governance, controls and accountability structures, ensuring alignment with regulatory expectations under CSRD, CSDDD and modern slavery legislation while remaining commercially practical.
Crucially, the service embeds due diligence into procurement and enterprise risk management, with clear ownership of mitigation actions, defined escalation pathways and governance structures that support informed executive oversight and transparent disclosure.
Frequently asked questions.
How is this different from general supplier monitoring?
Supplier monitoring typically focuses on collecting data or conducting periodic assessments. Supply chain due diligence, as defined by the OECD and UN Guiding Principles, is a structured, risk-based process that prioritises the most severe social and environmental risks, requires documented mitigation and remediation, and embeds accountability within governance and decision-making structures. It moves organisations from monitoring only to active risk management.
Will this meet CSRD, CSDDD and other regulatory requirements?
The service is designed in line with internationally recognised due diligence frameworks and evolving regulatory expectations, including CSRD, CSDDD and modern slavery legislation. It establishes a defensible, evidence-based approach that supports regulatory alignment and transparent disclosure. Final compliance outcomes will depend on how the system is implemented and maintained within the organisation.
Do we need full supply chain visibility to begin?
Effective due diligence requires a structured and proportionate risk-based approach that prioritises the most significant social and environmental risks and builds depth and coverage over time.
How does this integrate with procurement?
Risk prioritisation and mitigation planning should be embedded within procurement governance and supplier management processes. This ensures that due diligence informs supplier selection, contract management and ongoing performance review, rather than operating as a standalone compliance exercise.
Does this drive organisational change?
Effective due diligence requires clear ownership, defined mitigation pathways and governance integration. By embedding accountability across sustainability, procurement, risk and leadership teams, organisations move from policy-led compliance to coordinated, cross-functional risk management.
