Spirax scores 42/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified August 2026.
That places Spirax joint 230th of 650 companies scored, and 3rd of 7 in Industrial Equipment / Machinery.
Spirax exceeds near-term emissions targets and holds third-party verified data across Scope 1+2, but Scope 3 supply chain reduction remains unproven. Biodiversity assessment and renewable energy transition are active but incomplete. Weak points: circular economy metrics absent, water baselines still being established, full supply chain decarbonisation evidence pending.
