Halma scores 51/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified August 2026.
That places Halma joint 120th of 809 companies scored, and joint 3rd of 33 in Electronics / Hardware.
Halma has cut operational emissions 64% since 2020, but total footprint rose 2% in FY2025 because Scope 3 (99% of emissions) increased. Renewable electricity hit 86% via unbundled certificates, not additionality. Supply chain emissions lack formal supplier reduction programmes.
