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. Fees pay for the review, never the result. Last verified May 2026.
That places Asda joint 588th of 847 companies scored, and joint 37th of 48 in Retail (non-fashion).
