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.
