Babcock has validated science-based targets and publishes comprehensive Scope 1&2 data, but Scope 3 emissions—97% of its footprint—rose 29.7% since 2021. Renewable electricity sits at 30%. Water and waste management plans remain incomplete despite 2024 deadlines. The defence sector's embedded use-of-sold-products emissions dominate, masking operational progress.
Babcock International scores 36/100 (Below expectations) 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 Babcock International joint 459th of 847 companies scored, and 2nd of 4 in Defence.
