Monaco’s Mairie marked the 17th edition of its One Birth, One Tree initiative on Tuesday 14th April at the Jardin Saint-James, with the symbolic planting of a carob tree — a hardy Mediterranean species chosen for its robustness and longevity.

The ceremony was attended by Marjorie Crovetto, Deputy Mayor responsible for the Environment and Sustainable Development, several members of the Conseil Communal, and Stéphane Valeri, Président-Délégué of Monte-Carlo Société des Bains de Mer, which hosted the event and financed the symbolic planting this year.

A simple principle, now in its 17th year

Launched by the Mairie in 2008 in partnership with the Office National des Forêts, the programme operates on a straightforward premise: for every birth registered in the Principality, one tree is planted. It forms part of the global Plant for the Planet campaign, sponsored by Prince Albert II, which aims to plant one billion trees worldwide.

In 2025, 732 births were registered in Monaco — meaning 732 additional trees will be planted in the Saint-Auban area of the Alpes-Maritimes, reinforcing reforestation efforts in the territories surrounding the Principality. Since the programme launched, more than 15,000 trees have been planted by the Mairie.

Since 2020, the initiative has taken on an additional dimension through integration into the Îlot d’Avenir programme, which focuses on introducing tree species better adapted to changing Mediterranean climate conditions. The approach aims not only to restore forest plots but to serve as a replicable model for sustainable reforestation across the wider Mediterranean region.
