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 75th of 591 companies scored, and joint 3rd of 25 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.
