I don't know about all compounds but CFCs stay in atmosphere for about a century only and we've already banned them, and methane has a very short lifetime of about 12 years. So we 'only' need to control emissions of those to solve the problem.

On the other hand, as said, CO2 stays for centuries if not 1,000+ years so at this point net zero is only half the job.

Methane, at least, breaks down to CO2, no?

HFCs are not banned yet. They are responsible for 2500x CO2 forcing. Your car is leaking those right at this moment.
