The JUSTNEXUS project investigates sustainability transitions at the intersection of mobility, energy and housing. JUSTNEXUS aims to fundamentally rethink mobility by placing it in the context of energy and housing, and by stimulating innovative ideas and projects that accelerate just transitions for sustainability. With a diverse consortium, the project will explore the diversity of mobility challenges in three use cases in the Netherlands: a rural area in Friesland, an existing urban district in Amersfoort, and a new urban district in Helmond. Through a “Museum of the Past of the Future”, lessons from the project will be used to co-create new, just and sustainable visions of the future.
