I have no suggestions of groups, books, papers, blogs and etc regardin global constitutionalism, but I have an opinion.
Creating bigger and stronger governments will only lead to the protection of an elite that is way too irresponsible with their powers.
Right now the vibe is against oil, gas and pollutants and in favor of sustainability mostly globally. It’s genuinely very hard to find someone that says: “I don’t care about microplastics, “I have no issue with air pollutants causing cancer” and “I don’t care we are trashing the ocean”.
And this is sort of where solarpunk fits extremely well in. I don’t know if governments and corporations will solve the climate crisis, but goddamn I’ll do my part and help businesses and others do their part too.
This is one of the cases where I’d just argue for nuclear energy. Too many industries and too high population density makes it very hard to use solar energy properly, they don’t have a lot of land either so land redistribution probably wouldn’t work as an alternative measure.
