How pervasive are the changes due to high carbon costs?

This is a specific example of change of refrigerant in cars. How deeply will we as a society look at changes to our current systems in order to reduce carbon emissions? Is there a way to know whats next?

Car Industry Plans Shift to Low-Impact Refrigerant in A/C Systems

Fifteen years ago, the auto industry was forced to drop CFC-based refrigerant R-12 because of its liability for ozone depletion. They switched to non-CFC-based R-134a, which, as it turned out, also provided a substantial reduction in greenhouse gas liability. How much better is R-134a? Carbon dioxide has a global warming rating of 1. R-12 has a rating of 12,000. In other words, one pound of R-12 has the equivalent effect on global warming as 6 tons—12,000 pounds—of CO2. Years ago, that made R-134a’s rating of 1400 seem like a better deal. (As a point of reference, it takes one or two pounds of CO2 to dispense an entire keg of beer). But now automakers are considering a new refrigerant for worldwide use— R-1234yf. This new refrigerant has a global-warming impact number of just 4.
