Eni chief executive Paolo Scaroni has received a three-year jail sentence and a ban on holding public office for environmental violations at an Italian power plant while he was head of Enel. Scaroni denies wrongdoing and has said he will appeal. The court threw out a more serious charge of causing an environmental disaster, but ruled that the diesel-fired Porto Tolle plant had posed a risk. Franco Tato, another former Enel chief executive who denies the charges, was also found guilty, while Enel’s current chief executive Fulvio Conti and six other defendants were acquitted.
