There is policy that can be enacted based on the idea of putting a price on carbon to account for the externalities it generates. You can 1) cap and trade, 2) tax it.
California has gone with the cap and trade system, and has basically put a price on emitting carbon. It also has an offset program, which incentivizes carbon and greenhouse gas sequestration. This of course has the problem that you need to account for how much carbon a particular land use pattern in a particular region reduces. Regardless, California has the lowest carbon emissions per capita in the US [1].
Carbon taxes will result in less carbon emissions. They will disproportionately affect the poor because it is a flat tax. Canada gets around that by returning carbon tax revenue to tax payers [2] so you benefit financially if you emit less carbon. Contrast this with Australia, where the party that enacted a carbon tax was voted out of power and the tax repealed in 2014 [3].
Regardless, these are incentive structures to support reducing carbon emissions. What we really need is to eliminate the emissions and they way to do that is by making considerable and necessary changes.
