Costco: Consistently Mildly Negative
Costco's profile is flat. Most scores cluster around 0 to -30. No extreme highs, no extreme lows. The worst score is -40 on weapons, likely reflecting product lines that include firearms and ammunition in US locations.
Costco's approach to ethics appears passive: not doing much harm, but not doing much good either. Six zeros out of eleven values.
Walmart: High Highs, Low Lows
Walmart's profile swings. The +50 on Respect for Cultures & Communities is one of the highest scores for any retailer, driven by documented community investment programs, local hiring initiatives, and disaster relief contributions.
But Walmart scores -40 on Kind to Animals and -30 on Fair Pay & Worker Respect. The labour score reflects decades of documented wage disputes, class-action lawsuits, and criticism of pay practices.
What This Means
A single average number hides everything. These two companies score the same on average but represent fundamentally different ethical profiles.
Costco is neutral. Walmart is volatile.
For an investor who cares about worker rights, Costco is better. For an investor who cares about community impact, Walmart is better. A single ESG rating would tell you neither.
