The US could halve their emissions and still emit at the same level of an industrialized country like France. A good starting point is to invest more in nuclear energy.
Half is still a lot more than zero, which in turn is still not the negative you need to actually reduce the amount of carbon in the atmosphere. Carbon capture is the only option to undo the damage that's already been done, and to sustainably continue the activities where CO2 emissions are fundamentally unavoidable.
