Sadly I think the only viable route to this is wealthy countries paying poor countries to dismantle these power plants (and presumably replace them with something equivalent).
This has two nice benefits. One, wealthy countries show they act in good faith. Two, this will greatly reduce wealth disparity.
Of course, there's the chance some people will threaten to emit gas to acquire disproportionate power. This is true, but still preferable to the west just roasting the planet and then blaming china. Like grow tf up.
