The TRANSFORM project will investigate how civil society actors drive change towards transformative environmental governance. Current scholarship claims that such a change is a crucial element to improve our responses to climate change, biodiversity loss and the host of daunting challenges these pose. This viewpoint is shared by key actors in global environmental governance as well as civil society actors (CSAs), and all converge in underlining the need to shift away from the existing system of environmental governance rooted in understandings of the ‘environment’ as a set of resources. While emerging work on transformative environmental governance focuses on the fundamental elements that will characterise this governance model, there is less detail available about how such a transformation will come about. Although CSAs are seen as key drivers of transformative change, questions about how their actions will drive change remain.
