Echoing the Spaceship Earth metaphor and set 40 years after the Brundtland Report, it covers the full breadth of industrial ecology: quantifying pressures on shared socio-ecological spaces with material flow analysis, life cycle assessment and environmentally extended multi-regional input-output analysis, and strategies for regenerative and resilient management, from circular-economy interventions and nature-positive supply-chain redesign to industrial symbiosis, green infrastructure planning and ecosystem-service-based decision support. Themes include biodiversity, ecosystems and land systems; cities, buildings and infrastructure; climate and energy systems; food, agriculture and bioeconomy; governance, behaviour and sustainability transitions; input-output and economic systems analysis; life cycle thinking and sustainability assessment; and material and resource systems. Abstracts are accepted for oral or poster presentation, and researchers at all career stages are encouraged to take part.
