Howden Joinery 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 Howden Joinery joint 84th of 637 companies scored, and 3rd of 17 in Construction / Real Estate.
Howdens has assembled credible near-term climate targets (SBTi-validated) and operates closed-loop waste systems across UK sites, but Scope 3 emissions remain largely estimated, supplier verification covers only half of partners, and water impact sits unreported. A 2025 emissions rebound signals trajectory volatility.
