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.
Marriott International scores 34/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Marriott International joint 505th of 847 companies scored, and 12th of 13 in Hospitality / Hotels.
Where Marriott International sits among hospitality / hotels peers.
Among the 13 major hospitality / hotels brands we've scored, Marriott International sits 12th of 13.
Its three lowest-scoring questions, and what the evidence didn't show.
Intensity declined (US: 100.0 to 78.0 kg CO2e/m²), but absolute emissions increased 2022–2023 due to portfolio growth (7,800 to 9,000+ properties) and occupancy recovery.
2024: 36.4M MWh total energy consumed; only 3.4% from renewables across managed and franchised properties.
No TNFD disclosure, no quantified nature footprint, no deforestation-free commitment with verification.
