THE SUSTAINABILITY INTERVIEW
How supply chain complexity creates both risk and opportunity Walmart’ s supply chain is extensive and complex, encompassing thousands of suppliers across multiple sectors. This complexity presents challenges, but also significant opportunities for impact.
“ There are clear business benefits from working on value chains,” Kathleen explains.“ Including enhancing surety of supply – an antidote to volatility and uncertainty – enabling growth, managing cost structure and mitigating risk.” Supply chains are increasingly exposed to environmental risks such as climate change, resource scarcity and biodiversity loss. They also face social risks, including labour rights issues and economic inequality.
“ There are many challenges in value chains – but the sustainability practices help mitigate those,” Kathleen says. She believes that solutions to individual issues can benefit multiple stakeholders, strengthening Walmart’ s supply chain in turn.“ We prioritise hotspots and work in partnership with suppliers, NGOs and policymakers.”
This collaborative model recognises that no single company can transform global supply chains alone.
