Marriott International scores 34/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Marriott International joint 489th of 809 companies scored, and 12th of 13 in Hospitality / Hotels.
Marriott has SBTi-validated net-zero targets but is actively missing annual reduction milestones. Absolute emissions are rising, renewable energy penetration is stuck at 3.4% against a 30% goal, and Scope 3 supply chain coverage remains partial. Limited assurance on reported data and credible worker-impact criticism undermine claims.
