Rolls-Royce discloses Scope 1+2 emissions with limited assurance and reports 21% absolute reductions since 2019, but it has no SBTi-validated targets. Scope 3 coverage is narrow—only use-of-products measured at scale. Renewable energy at 18% remains marginal. Water, biodiversity, and end-of-life product circularity are unreported or nascent.
Rolls-Royce scores 27/100 (Significant gaps) 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.
That places Rolls-Royce joint 788th of 969 companies scored, and joint 5th of 9 in Aerospace.
