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.
Smiths scores 48/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified August 2026.
That places Smiths joint 198th of 847 companies scored, and 1st of 10 in Industrial Equipment / Machinery.
Smiths is the highest-scoring industrial equipment / machinery company we've rated.

Its three lowest-scoring questions, and what the evidence didn't show.
No quantified biodiversity footprint, deforestation-free commitment with third-party verification, or TNFD disclosure.
Circularity concentrated in Detection division; group-wide verified metrics not yet established.
No formal watershed-level stewardship programme; specific current targets and recent FY2024/25 absolute figures not confirmed in public search results.

Smiths leads its sector. These are the next 3 down.
IMI has verified Scope 1+2 emissions down 36% since 2019 and SBTi-validated net-zero targets.
See the breakdown →TOMRA operates a credible emissions reporting and SBTi-approved decarbonisation framework, but absolute emissions nearly doubled year-on-year, driven by Scope 3 expansion.
See the breakdown →Spirax exceeds near-term emissions targets and holds third-party verified data across Scope 1+2, but Scope 3 supply chain reduction remains unproven.
