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.
