AstraZeneca has cut operational emissions 88% since 2015, but Scope 3 has risen 24% above baseline and now comprises 99% of total footprint. Supply-chain engagement targets were missed, near-term climate goals were weakened in July 2026, and nature restoration is substantially off track. Transparency and third-party assurance are solid; the core problem is physics—absolute emissions are rising.
AstraZeneca scores 48/100 (Making progress) 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 October 2026.
