Costco Wholesale Corporation (COST) — ESG & Values Scores

Environment story

Costco discloses a Climate Action Plan with interim targets (39% emissions reduction by 2030, 100% clean energy at owned locations by 2035) but has explicitly stated it has no 2050 net-zero commitment and does not disclose forward Scope 3 trend data or detailed cost/ROI metrics for its transition. Deductions reflect undisclosed Scope 3 trajectory and absence of a credible long-term net-zero target; a partial addition is applied for disclosed physical efficiency and on-site renewable investments. This is a factual research summary, not investment guidance.

Criticisms on file

10-K discloses general environmental compliance risk from wastewater/stormwater discharge, refrigeration systems, and GHG-related regulation, with potential fines/penalties for noncompliance (no specific quantified incident disclosed).
