CFCs were a smaller problem, with cost effective alternatives available. So its more feasible to avoid The tragedy of the commons. In the case of CO2 and methane, its harder to move to more costly approaches given that you know that your competitor is not doing so (and possibly does not feel they can do so) and so would have a cost advantage over you, possibly putting at risk your actual economic viability.

There is often a reluctance to support more costly non-CO2 producing approaches to energy production given that those approaches have been around longest and are often cheapest.

Some renewable energy technologies are gaining market acceptance and are cost-competitive with hydrocarbons, but unless Tesla and its peers take off in a big way, hydrocarbons unfortunately aren't going away.
