Ranking of groups · Italy
Largest CO2 emitter owners in Italy, by group
The 58 CO2 emitter owners in Italy, each company counted under its ultimate parent and ranked by the verified emissions in 2025 of the CO2 emitters the group's companies own, operate or hold. Eni leads with 9,558,691 tCO2e across 9 CO2 emitters, held by 5 of its companies, ahead of French State (6,081,256 tCO2e) and Vitol Holding II S.A. (5,641,161 tCO2e).
A group is a parent company in the data and every subsidiary under it (GLEIF, Wikidata and the UK register of people with significant control); a company with no parent in the data is a group of its own. Each CO2 emitter counts once per group, in whole, or by the group's share where a source records one. A CO2 emitter with owners or operators in two groups counts in both, so the sizes do not add up to Italy's total. The 58 groups listed are linked to 80,844,194 tCO2e; the CO2 emitters in Italy with verified emissions in 2025 recorded add up to 67,009,898 tCO2e.
