Weir Group scores 31/100 (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 Weir Group joint 424th of 596 companies scored, and joint 3rd of 4 in Industrial Equipment / Machinery.

Weir discloses Scope 1 and 2 emissions under GHG Protocol with third-party limited assurance and is on track for its 2030 targets. Core weaknesses: Scope 3 emissions (99.7% of footprint) have risen 113% since 2020 despite restatement; water data collection only began in 2024 with no aggregate reporting; and biodiversity impact remains unquantified despite identified dependencies in metals supply chains.
