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. Fees pay for the review, never the result. Last verified October 2026.
That places Rolls-Royce joint 683rd of 847 companies scored, and joint 3rd of 9 in Aerospace.

Its three lowest-scoring questions, and what the evidence didn't show.
2023 Annual Report states Rolls-Royce 'continued to grow our understanding of our impact on biodiversity.' No TNFD-aligned disclosure.
No group-level water consumption or withdrawal data in 2023 or 2024 public filings.
