Walmart scores 27/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Walmart joint 650th of 809 companies scored, and 42nd of 46 in Retail (non-fashion).
Walmart's sustainability performance is defined by rising absolute emissions despite intensity gains, missed climate targets, and a widening gap between supply chain ambitions and verified delivery. Operations reporting is granular but negative in trajectory. Supply chain engagement lacks rigor, and trade association lobbying contradicts stated climate commitments.
