Let's not wait until it's too late to act! This is the conviction that animates the members, public or private actors, simple citizens or high level managers, mobilized together to act within the framework of One Planet.

One goal: accelerate the global transition to a more virtuous economy and to place climate and nature at the core of global recovery

The first One Planet Summit was held on 12 December 2017, exactly two years after the Paris Agreement was adopted.

Emmanuel Macron, President of the French Republic, Antonio Guterres, United Nations Secretary General, and Jim Kim, President of the World Bank Group, spearheaded this summit based on an obvious fact: to achieve the objectives of the Paris Agreement, we must make stronger commitments, more concrete decisions and mobilize all stakeholders in public life and the economic world in collaborative efforts.

Since then, each edition, summit or regional event is an opportunity for political leaders, private sector decision makers, foundations, NGOs and citizens to come together in order to identify and accelerate funding for climate, biodiversity and ocean solutions.

The next One Planet Summit will take place in Marseille with the goal to mobilize and act in favour of biodiversity.


Faced with the climate emergency and diminishing biodiversity, the commitment of political decision-makers alone is not enough.  The needed paradigm shift in all sectors requires that climate and environmental factors be integrated at the core of economic models.  Multi-stakeholder partnerships – that we call One Planet coalitions - are fundamental in order to break down silos and the implement low-carbon and green transition.

To scale up the ecological transition, the One Planet Summit promotes environmental and climate solutions that go hand in hand with employment, innovation and the creation of economic opportunities.  It serves as a platform for the international community and in particular for the 2030 Action Agenda.

Our duty is to act […]. The environment must be put back at the heart of the economy.
Emmanuel Macron, président de la République française
