The main objective of the Toolbox for the RRI experimentation is to provide the necessary methodological content to steer and support the development of the Transition Lab activities, which are based on exercises such as self-reflection practices, foresight methods, the identification of needs, and the implementation of innovation calls . This knowledge-base toolkit also conveys resources on European projects, initiatives and documentation based on Responsible Research and Innovation routines and Smart Specialisation practices in connection to Energy Transition pathways and transformative change.
