The vision of the One Planet Summit is to offer a new, pragmatic and effective framework for action, one that will contribute to broadening and renewing international cooperation for the ecological transition. A platform for joint commitment bringing together all these stakeholders, and their willingness to act, generates many synergies. Tangible and useful solutions on the ground emerge, resulting in a turning point for the environment. The One Planet Summit also helps incorporate climate and environmental challenges into the very core of development models, on a global scale.
