Interface is a rare manufacturing peer with genuine 28-year carbon reduction track record: 96% absolute GHG cuts since 1996, 4% further reduction in 2024, and SBTi-validated 2030 targets already half-met. Circularity leadership is real—31,750 tonnes collected via ReEntry, 51% recycled content, 92% landfill diversion. Gaps: water data is intensity-based not absolute; nature impact remains pilot-stage; no B Corp lock or executive pay linkage to targets.
Interface scores 60/100 (Leading practice) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
