BAE Systems reports operational emissions reductions and renewable electricity, but Scope 3 disclosure is severely understated for a defence manufacturer with multi-decade product lifecycles. Major gaps remain in supply chain transparency, biodiversity strategy, and water management. Historical bribery convictions and misaligned trade association memberships undermine credibility.
