University leaders ‘must decide what sustainability means’

This is a strange, unattainable outcome. Its better to define logics and throughputs that reproduce unsustainability in the context (place based, but not always), and then consider the options to go about this. Not words. Words have multiple sub-meanings, act as placeholders, act to save face, job security, ego etc. They take different forms depending on the higher orders they operate within e.g., marketisation, neoliberalism.
