Enel has launched a €1.25bn ($1.33bn) green bond issue, the first by the Italian energy giant as it moves to underpin its ambitious transformation to a clean-power future.

The bond issue, which matures in September 2024, attracted about €3bn of subscriptions “with considerable interest” from socially responsible investors, enabling Enel to further diversify its investor base, the Italian group said.

The green bond is expected to be listed on the Irish and Luxembourg stock exchanges.
