Our verdict

Lenovo publishes credible climate data with third-party verification and SBTi-validated targets, but relies heavily on intensity-based Scope 3 metrics that allow absolute emissions to rise. Its 99% Scope 3 footprint remains largely uncontrolled. Nature impact is entirely unmapped. Transparency is strong; actual decarbonization leverage is weak.

Lenovo scores 39/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.

That places Lenovo joint 432nd of 934 companies scored, and joint 16th of 37 in Electronics / Hardware.

What is Lenovo doing well, and where does it fall short?
