Well, I know in France there was a citizens convention for the climate that developed citizens-led initiatives such as banning short flights and so on. That's significant. When you say "consumers would revolt against these policies", would they? Because representative citizens assemblies pretty much prove you otherwise, these are not political activists that got together to push an agenda; it's the result of a representative (through sortition) sample of the french people. Maybe in America things would be different, but I honestly wouldn't say with certainty that it is so.
Although for the citizens convention for the climate in France from the ~180 proposals only 30ish were approved by congress. So this shows the tension between what people might want and what congress is willing to pass; probably because congress is under a much higher pressure from lobbying, so they're much less bold.
But really, my point here is that there are political alternatives. These are not very well known but they're very much real. I know climate movements and activists in other countries, such as Norway, are very much aware of these and these are the policies they want to push for.
So I would say, really, there's a big difference between not knowing and not being involved and actually not any viable alternatives to the problem being out there. I would say the first step is awareness and is involvement. Literally, just talking about it in a serious manner and not simply going "ugh, but politics is so useless!". Ask yourself why and what is being done and what people are trying out there. Because a lot is being tried, particularly in Europe. Just get involved locally and bring these ideas forward.
Basically what I'm saying is we should be pushing for a "let us actually decide for ourselves" movement rather than specifically something about climate. And this I believe is something a lot of people can agree on, from the current polarized political spectrum. As there is a very real crisis of representation in our democracies. No one likes politicians.
