Eni is a legacy oil and gas company dressed in transition language. Despite comprehensive emissions reporting and renewable subsidiaries, its core business remains fossil fuel extraction with minimal structural decarbonization. Scope 3 emissions barely decline, greenwashing fines have been levied, active climate litigation proceeds against it, and its climate advocacy actively opposes Paris-aligned policy.
