Smiths has demonstrated consistent absolute emissions reductions across operations and supply chain, with SBTi-validated net-zero targets and executive pay tied to GHG outcomes. Major weaknesses: supplier engagement is nascent (9% SBTi-aligned), biodiversity work remains at assessment stage, and circularity is concentrated in one division.
