Cigna reports operational emissions largely covered by renewable certificates rather than power purchase agreements. Its 12.0 Mt Scope 3 is mostly purchased goods (6.9 Mt, largely spend-based) and PCAF-basis investments (5.0 Mt). Its SBTi targets are submitted but not yet validated, no biodiversity assessment was found, and it pays dues to the US Chamber of Commerce and Business Roundtable.
