Saudi Aramco is the world's largest corporate emitter, refusing to disclose Scope 3 emissions (~1.6–1.84 Gt CO₂e annually, 4.4% of global emissions). Operational emissions are rising, targets are intensity-only while production expands, and the company actively lobbies against climate action. Scope 3 non-disclosure alone is disqualifying.
