A flowchart diagram representing procurement as the key interface for sustainability. The diagram is divided into several interconnected sections. At the top left, policy signals include environmentally sustainable procurement policy and recycled first policy. These signals influence procurement, which involves contract requirements, tender evaluation criteria, and supplier obligations. Procurement impacts three main areas: materials, supplier behavior, and construction practices. Materials focus on material selection. Supplier behavior involves compliance and reporting. Construction practices pertain to site operations. These areas collectively influence the outcomes, which are embodied carbon and circularity. Arrows indicate the flow and relationships between these components, emphasizing the role of procurement in driving sustainability throughout the project lifecycle.Procurement as they key interface for sustainability
