Citroen is one of the partners for the latest project on Chalki in the Dodecanese archipelago in the Aegean Sea.
It comes after Volkswagen earlier signed a pioneering deal with the Greek government to replace around 1,500 polluting cars on Astypalaia island with electric vehicles, scooters and bikes.
The schemes on both islands include hundreds of public charging stations, as well as "intelligent street lighting systems."
In the initial phase, Citroen is providing six fully electric vehicles to public authorities in Chalki island.
The vehicles are being supplied on a free 48-month lease after which Citroen will buy back the cars and donate them to the municipality of Chalki.
"We are very proud to contribute to the transformation of Chalki island into an island which will be autonomous, smart and sustainable," said Citroen CEO Vincent Cobee.
The Greek islands of Kassos, Sifnos, Kythnos, Alonissos and others are interested in similar initiatives as part of a EU project to promote green transport and a significant reduction in carbon footprint.
