Welcome to the launch of the United Co-Creation Lab (https://www.unitedcclab.org/), an initiative that brings together young people and global leaders to collaboratively create ethical and sustainable solutions for the future. Our goal is to demonstrate how intergenerational co-creation can generate innovative ideas, promote democratic engagement, and inspire the next generation of leaders. This UN Summit of the Future side event focuses on understanding the needs and prerequisites for effective cocreation, sharing practical examples from initiatives in Grigny, France, and the Open Urbanism Foundation, and will discuss the challenges and strategies to overcome obstacles to collaboration. The objective of the event is to deepen participants' understanding of the power of co-creation. Politicians can see how working with young people advances democracy and human rights, while achieving better solutions for global challenges. We also aim to inspire young people to harness their creativity and kindness to shape a more sustainable, just world. By combining diverse disciplines such as art, design, and architecture, the United Co-Creation Lab emphasizes the importance of ethical collaboration to address issues like climate change and social justice
