Asda reports Scope 1/2 emissions with GHG Protocol rigour and has cut operational carbon 48% since 2021, but Scope 3 — 98% of its footprint — remains largely unverified and uncut. Its SBTi targets were removed in 2024; self-set net-zero claims lack external validation. A CMA greenwashing undertaking and EIA criticism on refrigerants expose weak execution on climate commitments.
Asda scores 31/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.
