Diageo scores 46/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Diageo joint 225th of 809 companies scored, and joint 14th of 45 in Food & Beverage (non-meat).
Diageo has cut its climate targets significantly—halving Scope 3 reduction from 50% to 26% and pushing net-zero operations from 2030 to 2040—while claiming validation against 1.5°C science. Operations emissions fell 18.8% since 2022, but total value-chain emissions rose. A £1.2m regulatory fine for unreported climate pollution, delisted SBTi targets, and a product-integrity lawsuit expose weak accountability.
