Go for it - foster a culture of sustainability. That’s not a bad thing, it’s just inadequate.
Do you think that’ll deliver the change we need, dramatically shifting the behaviour of corporations and billions of people before we’re out of time, or do you think that pushing those that set the rules of our society to force/motivate the corporations might do a more effective job?
You’re talking about fundamentally breaking capitalism, which I’m all for, but to imagine that those holding the wealth, and by extension, the power will be influenced to abandon the profit motive by some flowery language rather than pushing back against you to the greatest extent possible is magical thinking. You need the greater power of the government to force that change on them.
