The mission of the Common Home of Humanity is to contribute to build a new global governance system for humanity based on the legal recognition of a well-defined well-functioning Earth System as an Intangible Common Heritage of Humankind. This new object of International Law should be the basis around which the relations of interdependence that emerge from the shared use of a unique and highly interconnected Earth System at a global scale are organized, producing cascading effects on health, economy, social justice and international relations. Common Home of Humanity is a novel initiative conceived in 2016 in recognition of the enormous governance challenge that global interdepence poses to human societies in their efforts to ensure a sustainable future for humankind. Within a truly global, inter and trans-disciplinary effort, the Common Home of Humanity works to build a global transformative movement to create the needed structural conditions for a colective action for our civilization to safeguard a well-functioning Earth System.
