Kaiser Aluminum Corporation (KALU) — ESG & Values Scores

Environment story

Kaiser Aluminum demonstrates moderate environmental performance with documented legacy remediation liabilities and no disclosed net-zero target, resulting in material score deductions. The company reports $0.3 million in environmental expenses for 2025 related to legacy contingencies from activities prior to 2006, indicating ongoing remediation obligations. Scope 1, Scope 2, and Scope 3 emissions data are entirely absent from disclosed filings, and no renewable energy percentage or decarbonization infrastructure investments are specified. The 10-K notes potential undisclosed environmental costs could exceed current accruals by up to $14.1 million. No net-zero commitment or intermediate climate targets are disclosed. The company operates energy-intensive aluminum production facilities across 10+ locations but provides no greenhouse gas inventory, energy efficiency roadmap, or verified decarbonization initiatives. The absence of supply-chain carbon disclosure and operational emissions baselines represents a significant gap in climate transparency for a heavy manufacturing company.
