Sustainability requirements: Walmart’s supplier sustainability guidelines emphasize emissions reduction, waste elimination, natural resource preservation, and adherence to sustainable sourcing standards. Through initiatives like Project Gigaton, Walmart engages suppliers in six key areas—energy, waste, nature, transportation, packaging, and product design—to support greenhouse gas reduction. Walmart also prioritizes sustainable commodity sourcing and has set specific targets for using recycled materials, eliminating virgin plastics, and achieving responsible sourcing certifications for certain commodities. Suppliers are encouraged to adopt and report on sustainable practices to align with Walmart’s broader environmental and social responsibility goals.
