Degrowth

Yeah I mostly agree here, but there are two extra bits I'd want to add:

For one things like a well run cap and trade system(no offsets) for emissions

See how you had to add a bunch of clarifying comments, so if I point at a bunch of existing cap-and-trade systems you'd have to sigh and say "no, this one also sucks"? That's what I mean when I say that any idea we can create will immediately get re-interpreted into something completely toothless. I'm not saying we don't need to fight here, I'm saying that Degrowth doesn't have a marketing problem. Even the places with a carbon tax charge way too little. The fangs are a feature.

The narrative should be from rich to poor no matter what

I agree here but also, the poorer countries have vastly superior sustainability options because waste is simply much harder to deal with there. You can't throw a plastic bottle away because there's no rubbish bin to put it into. There's no garbage trucks, everything is more or less recycled because the government doesn't do that job. The places are also more dense and walkable by necessity, because people can't afford cars. The "rich" countries need to rebuild back what the poor countries already have. Someone from a richer country ipso facto must emit more, so it's all about re-aligning society to be more sustainable.
