Wickes has credible emissions reporting with SBTi-validated targets, but total footprint rose 28% in 2022 due to Scope 3 methodology improvements masking weak absolute trajectory. Renewable electricity is now 100% sourced; timber is responsibly certified. Critical gaps: no quantified nature footprint, water targets absent, waste circularity still under development, and rebaselining delays signal target instability.
Wickes scores 45/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Wickes joint 258th of 847 companies scored, and joint 10th of 48 in Retail (non-fashion).
