Responsible value chain

We seek to apply responsible business practices throughout our value chain by sourcing responsibly and enhancing product stewardship.

Our aim is to build strong, mutually beneficial relationships with stakeholders and to work with suppliers and customers whose values and conduct align with ours.

Our focus areas

Managing supply chain risks

Including those related to safety, supply security, business integrity, human rights (including modern slavery) and financial stability, through a range of coordinated and integrated activities.

Guided by leading industry standards and best practices in the handling, transport and use of our commodities to support responsible product stewardship.

Local procurement and supplier development

Sourcing goods and services from local businesses that meet our health, safety, environmental and social performance requirements, and support small, medium and micro enterprises that are part of our supply chain.

We rely on a diverse supply chain of over 5,700 suppliers across 50 countries to provide the non-traded goods and services essential to our operations, and work with more than 180 customers.

Managing supply chain risksExpandCollapse

We manage supply chain risks, including those related to safety, supply security, business integrity, human rights (including modern slavery) and financial stability, through a range of coordinated and integrated activities.

These include:

  • Onboarding due diligence: Our Business Integrity team and subject matter experts assess suppliers based on their risk profile and work scope, setting evaluation criteria and controls;
  • Continuous monitoring: We work with third-party auditors to assess labour rights risks among existing suppliers;
  • Collaborative remediation: Where issues are identified, we engage directly with suppliers to support remediation and improve practices;
  • Process and system improvements: We continue to make enhancements throughout the supplier lifecycle to strengthen compliance and improve visibility of supplier performance;
  • Risk insights: We use third-party risk assessment tools to increase visibility of social and environmental supply chain risks; and
  • Training: We provide mandatory modern slavery training for select roles across our business to build awareness and capability in identifying and addressing these risks.
Modern slavery ExpandCollapse

Our supplier risk evaluation process enables us to identify and assess modern slavery risks among suppliers of non-traded goods and services.

This process applies throughout the lifecycle of a supplier’s engagement with us, and includes risk mapping, mandatory risk assessments during onboarding, risk-based evaluations through desktop reviews and external audits of select suppliers.

Maritime activitiesExpandCollapse

We do not own ships or employ seafarers, but rely on maritime transport for delivery of supplies and our commodities.

We conduct modern slavery risk due diligence, including vetting, audits and inspections in compliance with the Maritime Labour Convention, and support human rights initiatives through contributions to the Mission to Seafarers and its Seafarers Happiness Index. We also participate in the SEAFAIRER roundtable on seafarers’ rights and welfare, and are members of the Sea Cargo Charter.
