On 12 December 2017, the President of the French Republic, Emmanuel Macron, the President of the World Bank Group, Jim Yong Kim, and the Secretary-General of the United Nations, António Guterres, decided to refute fatalism in the face of the ecological emergency for our planet by calling together in Paris international leaders and committed citizens from around the world.
Together, on 12 December 2017, they launched an ambitious project to win the battle against climate change.
12 commitments were made, the One Planet Coalition was created. It will ensure that the commitments are kept. The coming months will be dedicated to implementing the commitments and we will meet again next year for a project meeting: the second One Planet Summit.

Projects for our planet.

At the heart of the Summit, some 20 projects have been showcased. These projects were presented during the round tables in the morning, the Climate Agora at lunchtime and during the afternoon sessions. They illustrate the fact that concrete local and global solutions exist to address the challenges we face. They need to be stepped up and replicated, and to serve as a source of inspiration around the world. They demonstrate that we are committed to a new world, to preserve the future of our one and only planet.

In parallel of the One Planet Summit on December 12, many side events are organized on December 10, 11 and 13 in Paris by public, private and civil society stakeholders in order to contribute to the mobilization and the implementation of concrete solutions towards greater climate action.
