I took a quick glance at the doc and no where is “sustainability” defined. I have yet to see the term defined especially in economic terms. As near as I can tell it means doing something other than what we’re doing (which works) that makes the enviro-fascists happy.
IMO, Sustainability = carrying capacity of between 75 & 80%. Tops.
“sustainability” is the mantra of leftist eco-fascists everywhere
you’re right, it’s usually left undefined, that way it is an infinitely malleable tool of global socialist bureaucrats
of course they never care about “sustainability” of national budgets or financial commitments, “sustainability” of unlimited commitments to welfarism and “social justice”.... or sustainability of anything that a majority of Americans actually value
