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.
Spirax scores 42/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified August 2026.
