Human-centred design (HCD) is just that: human-centred. As we approach the limits of Earth's biophysical systems, it no longer feels appropriate to place humans at the centre of design decisions. Yet HCD and its ISO-ISO-9241-210:2010-continue to be powerful and popular tools within many computing and design departments, as well as in their a liated industries. ese design approaches are perpetuating the trend of incremental improvements to the living standards of the already privileged and digitally connected whilst ignoring the broader environmental and socio-political e ects of digital technologies. In this paper, we a empt to reimagine HCD and its ISO by drawing on elds and concepts such as sustainable interaction design (SID), animal-computer interaction (ACI), and object oriented ontology (OOO). rough this, we contribute a preliminary set of proposals about what needs to change with HCD and its ISO. We close by discussing the ISO development process and suggesting routes for environmentally concerned researchers to in uence the evolution of HCD's ISO.
