Climate policy fails because the proposals are eye-wateringly expensive, amounting to trillions of dollars annually. In contrast, the CFC protocols and treaties worked splendidly because they were cheap, costing only billions of dollars to switch to chemicals which didn’t interact with ozone.
Changing the amount of CO2 in the atmosphere is not the only way to change the climate, and is unlikely to be the cheapest way to change the climate. But acknowledging that would require having a diplomatic/societal technology to determine what the optimal climate should be.
