On the one hand, there is a school of thought that the growth model of economics has outlived its usefulness and that now we need to move to 'steady-state economics' such as those promoted by Herman Daly. There is a good discussion of this on the website of LILI (Low Impact Living Initiative).
On the other hand, in order to be pragmatic in the short- to medium-term, we need Green Growth to happen, largely within the existing economic growth-based model, in order to keep the lights on while at the same time preventing runaway climate change.
This means that sustainability experts of future generations will need to be capable of holding at least two competing fundamental conceptual frameworks in their heads concurrently but continuing to operate effectively and practically in the real world to navigate and drive difficult transitions between the two.
This reminds me of a Wiki quote:
"The test of a first rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function"
The original source of this quote is F. Scott Fitzgerald, "The Crack-Up", Esquire Magazine (February
1936).
