Sustainability requirements: Bristol Myers Squibb requires preferred suppliers to participate in its Responsible Sourcing Program, using EcoVadis for ESG assessments. Suppliers are evaluated and categorized into tiers—Aspirant, Achiever, or High Achiever—based on their sustainability performance, with reassessments every 12, 24, or 36 months, respectively. Suppliers are expected to address identified gaps, set annual science-based sustainability goals aligned with global standards (such as the Paris Accord), and report progress publicly through third-party platforms. Bristol Myers Squibb encourages high-performing suppliers to partner on sustainability innovations and implement responsible sourcing practices across their own supply chains.
