Well, the alternatives for CFC-generating are already developed and in the marketplace. There are still no equivalent alternatives for many oil-using products. Kind of indicates that it is technically easier.

The fact that there are CFC replacements but not oil replacements for all use-cases indicates that it's more difficult, no?

> basically everyone agrees it's cheaper to deal with climate change

I'm not sure that's the case. Seems like a lot of people are either hoping that it's not going to affect them that much, or that some miracle technology will be developed which will fix the problem more cheaply and not require any change in behavior on their part.
