The research group "Green transitions" works with various topics within sustainable development, and is happy to use both Urban Living Lab (ULL) methodology and other co-creative processes to gain new knowledge and work toward the sustainable development of places and industries. Green transitions" is a broad concept open to different interpretations, definitions and practices, ranging from green versions of today's dominant economic systems (green growth) to more radical transformations of the same systems (downsizing). What characterizes “development” - a key concept in the social sciences in recent decades - will similarly be the subject of a wide range of interpretations. At Telemark Research Institute, we recognize this complexity, and that power and politics influence which choices are made. Our researchers have different approaches to issues related to these concepts. In our research, we therefore strive for a comprehensive and open discussion about the challenges of sustainability and future choices, with an underlying value focus on social and environmental justice.
