Significant gapsPending Review

Dunkin' discloses almost no quantitative environmental data despite operating 13,000+ restaurants globally. Emissions figures, water consumption, and waste volumes remain unreported. The company completed a foam-to-paper cup transition in 2020 but relies on unverified claims and lacks science-based targets, third-party verification, or net-zero commitment.
