Babcock International scores 36/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified October 2026.

That places Babcock International joint 444th of 809 companies scored, and 2nd of 3 in Defence.

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.
