Sustainability requirements: Starbucks requires its suppliers to adhere to stringent environmental standards as part of its commitment to sustainability. The company expects suppliers to actively reduce their environmental impact by minimizing waste, managing water use efficiently, and reducing greenhouse gas emissions. Suppliers must also comply with all local environmental laws and regulations, implement sustainable practices in their operations, and regularly report on their environmental performance. These requirements are designed to support Starbucks' goal of reducing its carbon footprint and promoting sustainability throughout its supply chain.
