Cisco has achieved genuine absolute emissions reductions across all scopes with SBTi-validated net-zero 2040 targets and 96–100% renewable electricity. Supply chain engagement and circular design gains are measurable. The core weakness: total emissions remain massive (>17M tonnes annually) driven by product use-phase energy, and nature impact quantification is missing despite supply chain mining exposure.

Cisco Systems scores 46/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.

That places Cisco Systems joint 235th of 847 companies scored, and 8th of 33 in Electronics / Hardware.
