Aviva demonstrates solid operational carbon performance and renewable energy procurement, but relies on offsets for carbon neutrality and maintains material fossil-fuel underwriting. Supply-chain emissions tracking is incomplete, biodiversity targets lack quantification, and water stewardship is absent. As a composite insurer, Aviva's core structural problem is underwriting new oil and gas development.
