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.
