Howden Joinery scores 52/100 (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 Howden Joinery joint 99th of 807 companies scored, and 3rd of 20 in Construction / Real Estate.
Howden Joinery has delivered material absolute emissions reductions and achieved its 2030 Scope 3 target ahead of schedule, backed by SBTi validation. Critical gaps remain: water consumption is entirely unreported despite manufacturing operations; nature impact disclosure lacks quantification and TNFD alignment; and long-term net-zero pathways beyond 2030 lack independent validation.
