Dunkin' discloses almost no quantitative sustainability data despite operating 13,000+ restaurants globally. Emissions figures remain unpublished, supply chain carbon is entirely unquantified, and no science-based targets exist. The company resolved its foam cup controversy in 2020 but continues to rely on single-use packaging and greenwashing claims unsupported by measurable action.
