Achieving a transition from the current fossil fuel based economic system to a configuration of green growth is a challenge of global scope. With many heterogeneous entities (individuals, households, companies, institutions, governments, etc.) interacting in networks on multiple levels (e.g., cities, regions, nations), the underlying systems are complex systems. With knowledge and values playing equally important roles in decision making on this subject, stakeholders need to be involved for understanding, as well as addressing this challenge.
This contribution discusses useful concepts and tools from different fields, including economics, complexity, risk governance and global systems science. As an example case, it considers a sustainable mobility transition, presenting an agent-based model of socio-technical change of mobility demand, together with a process for conducting model-supported stakeholder dialogues for knowledge acquisition and decision support.
