This comprehensive effort to manage the supply chain and outsourced services is a direct and actionable part of the UNIMAS Low Carbon Campus Roadmap 2030. Specifically, the plan to evaluate the carbon footprint resulting from supplier and caterer movements is listed under the Roadmap's Strategic Pillar 3: Circular Economy and Waste Management. By extending accountability to these external partners and implementing the zero single-use plastics policy, UNIMAS ensures that its core environmental principles—minimisation, waste reduction, and responsible procurement—are enforced throughout its value chain. This strategy is critical to achieving the Roadmap's ambitious targets of a 40% reduction in waste generation and a substantial reduction in Scope 3 greenhouse gas emissions, positioning the university as a leader in integrated sustainability practices.

UNIMAS ensures that its disposable-reduction policies are applied not only within the university but also across outsourced services and its supply chain, as reflected in its ESG Policy and operational guidelines. Through the Ethical & Sustainable Procurement section of the UNIMAS ESG Policy, all suppliers and contractors—including food vendors, caterers, cleaning contractors, and waste-management service providers—must comply with sustainability standards such as reduced single-use plastics, responsible packaging, and environmentally safe practices. Outsourced waste disposal is handled by licensed contractors (e.g., Trienekens Sdn Bhd) who operate in full compliance with the Environmental Quality (Scheduled Wastes) Regulations 2005, ensuring that legal and environmental standards apply beyond campus operations. UNIMAS also requires food and beverage operators on campus to follow non-plastic container guidelines during events and everyday operations, meaning that sustainability expectations are embedded into vendor agreements and procurement processes. Through these mechanisms, UNIMAS ensures that sustainable-disposal and plastic-reduction commitments extend consistently across its entire supply chain and outsourced ecosystem.
