In 2022, the Parc national des Calanques responded to the AMI (Appel à Manifestation d’Intérêt) launched by CITEO which aims to identify the combination of concrete actions that will address the issue of litter, better understand and objectify the subject, and bring about effective action against the pollution they generate.

The aim of the project is to set up a plan to prevent and tackle littering in the Parc national des Calanques, in association with all the stakeholders involved. MerTerre is in charge of carrying out the shared diagnosis phase and assisting with the co-construction of recommendations.
