Emerging technologies are defined as technical innovations fulfilling five criteria: radical novelty, relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. They find application in technology (e.g. artificial intelligence, robotics, 3D-printing, nanotechnology), medicine (e.g. gene therapy, cancer vaccines), food (e.g. in-vitro meat) and urbanism (e.g. smart communities), having potential to yield benefits to society and contribute to sustainability. Nevertheless, due to their novelty, holistic assessment is needed to understand benefits and risks from a life cycle perspective. This session aims to gather contributions showing how Life Cycle Thinking can feed into assessment and, potentially, future regulation of emerging technologies.
