How is nuclear power not a "unilateral emissions cut"? If we start using more expensive nuclear power, then that will 'hurt' our economy (because we could have more nominal money if we bought the cheapest power). I think nuclear power would be great for the climate and we should pursue it, but it would be great in exactly the same way as any other unilateral emissions cut would be great (eg. tax incentives for electric cars, or a carbon tax, or replacing coal plants with wind farms).
