Political viability differs a lot between polities. Oregon shut down its last coal plant this year. Oregonians can't vote to shut down West Virginian coal plants. Oregon can't impose carbon tariffs to nudge other states, either, since interstate commerce is the domain of federal power. But Oregon can theoretically get to net 0 emissions by deploying carbon capture in tandem with their own ongoing phaseout of fossil fuels. Carbon capture is the least bad option once a polity has cut its own internal emissions as much as practical and has tried and failed to get other polities to make similar cuts.
