Haleon scores 50/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified September 2026.

That places Haleon joint 102nd of 680 companies scored, and joint 3rd of 15 in Healthcare / Pharmaceuticals.

Haleon reports comprehensively on Scope 1+2 emissions and has achieved 100% renewable electricity, with verified 55% net reduction versus 2020. Supply chain Scope 3 coverage remains patchy and relies on purchased offsets rather than absolute cuts. Water stewardship is certified across all sites, but TRUE waste certification covers only 46% of facilities. Execution lags commitments: the company achieved just 23% of its planned 2024 operational reduction target.
