We'll need to send another Sagan vinyl up to warn about the dangers of Capitalism among societies.
IPCC claims we need to expand beyond capitalism to solve this [1].

If you want a government that does that, you would have to give all power to a small group of people like you. That would never happen because there are so many groups with other immense interests that if you are going to let one "win" and control everything the odds of you winning are almost nil. The only option is to somehow get more people to want to change everything.
Are they capitalistic or economies though? Right wing systems that value privitization? Countries that are cutting emissions in extremely significant manners (relative to their countries, they can't control the world), and putting out well reachable net-zero emissions goals, are the furthest left wing countries in the world at the moment that have checks on Capitalism.

Yet its market operates more like a capitalistic one.
It's also not entirely fair to point the finger wholly at China on CO2 output when Europe and the US have effectively outsourced their manufacturing and most polluting processes to companies over there.
They've in a sense found a way to use Marx's critique of capitalism towards its opposite intent. Marx saw the authoritarianism inherent in the market and how it was tied to wage labour exploitation? The Chinese Communist party has harnessed that authoritarianism to increase exploitation to its maximum.
The Communist Party in China are as "communist" as the later Roman emperors were "Christian."
No, therefore China is not a communist state. It is one in name only. Its economy is extremely capitalistic.
China is, actually, the living proof capitalism works a lot better without a democracy holding it back.
Marx's commentary on so-called democratic states: "The executive of the modern state is nothing but a committee for managing the common affairs of the whole bourgeoisie" rings quite true today. In China they've perfected this by getting the pesky petty grumbles of the population out of the way.
