Unilever values sustainable sourcing for its product ingredients. To this end, the company has developed its own sustainable agriculture program. Because peanut suppliers comply with this program, the Calvé peanut butter jar proudly displays a logo stating, "We use sustainably grown peanuts." On the back, near the ingredient list, there’s a QR code linking to more information about the program. But is this claim compliant? Sustainability claims must meet strict requirements: they must be clear, specific, accurate, and unambiguous.
