BAE Systems scores 40/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places BAE Systems joint 358th of 809 companies scored, and 1st of 3 in Defence.
BAE Systems discloses operational emissions with GHG Protocol alignment but lacks third-party assurance for 2024 data. Scope 3 reporting severely undercounts defence platform operational emissions over multi-decade lifecycles. A 2010 bribery settlement and ongoing memberships in climate-negative trade associations expose unresolved governance gaps.
