Rolls-Royce discloses operational emissions with third-party assurance but masks weak absolute reduction trends behind intensity metrics. Scope 3 quantification remains incomplete, SBTi targets unvalidated after five years, and the company actively advocated to weaken aviation climate regulation while sitting on association boards with negative climate engagement.
