At first blush, normative arguments justifying representation of future generations and nature appear to rest on contradictory values. This article argues, however, that there are strong synergies between these discourses. Arguments for institutions for future generations based on human rights are compared with justifications for proxy representation of nature based on ecological justice, Indigenous ecological justice and socio-ecological justice. Case studies involving the Welsh Commissioner for Future Generations, the Aotearoa New Zealand Parliamentary Commissioner for the Environment, and ascribing legal personality to rivers in Australia and Aotearoa New Zealand, are presented to demonstrate that representing future generations and nature reflect mutually supporting values. Building on these synergies is vital for reform efforts.
