As a matter of policy? Universal carbon-tax with increasing fee schedules. Everyone pays for their carbon emissions. The sum is then distributed back to everyone evenly as a Green Dividend minus admin costs. Net zero cash to the government, whopping undirected green energy subsidy possible by tuning amounts. It already worked for Sulphur Dioxide.
As a matter of personal preference? Well, I get nothing from this except the right to brag I'm carbon negative so really it could totally be equivalent to indulgences. As it so happens I do care to be doing my part, but you're right in that there's no incentive for that.

Right, but I live in California and have no AC.
How does that work in practical reality so it doesn't just turn into a money making scheme with no real impact akin to Catholic indulgences?
> Also, it's a little bit rich to listen to any sort of climate talk from anyone in cold countries¹. They emit so much carbon just to be warm. Well, I don't, because I live in California.
How many emissions in the US come from the use of AC and heating due to basically zero federal building standards for energy efficiency? [0]
Afaik AC is generally considered way more inefficient, heating can be captured as a side-product from a lot of processes, cooling not so much.
