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.
