Abstract: As well as presenting an opportunity to understand where commonalities exist between degrowth advocates and others calling for a transition to an environmentally sustainable economic system, this analysis will highlight the causes of disagreement in views of how an environmentally sustainable economy might be achieved. Our NETGREEN research identifies the trail of logic that shapes individuals’ views of which pathways should be taken in order to reach an environmentally sustainable economy, and clearly identifies the points at which divergence in views occurs. By considering the key assumptions that these views are premised on, our research will demonstrate why different views on how to achieve environmental sustainability exist. The research is based on analysis of over 100 texts written about transitioning to an environmentally sustainable economy, interviews with 55 experts from the field, and a participative, discussion-led seminar with 35 experts from the field. Throughout the research, we have attempted to consult a wide range of views from across the spectrum from degrowth to green growth advocates, and those in between.
