For everyone? Nuclear Fusion is on the cusp of reaching net zero emissions. Meaning we can create massive amounts of clean energy. Right now, we use nuclear energy off of Nuclear Fission creating hazardous waste and resulting in excess heat/waste
Nuclear Fusion would allows us to create clean energy with the goal of being net zero
Nuclear Fusion and "net zero emissions" doesn't really make sense.
What I think you are trying to say is that fusion is nearing the point where net energy is possible (that is getting more energy out then the amount of energy put in to create the reactions in the first place). Fusion is not practically close yet, but there are tantalizing hints that we are close.
See this from 2022; the national ignition facility produced more energy that was impacted on the target (2MJ in 3MJ out), but this doesn't take into account the huge inefficiencies in the laser generators to produce that 2MJ laser pulse.
There are a bunch of fusion experiments that are hitting massive temperatures (120 - 150MK) which is starting to get into the range where practical fusion could occur, the center of the sun is approx 15MK but also has massive gravity to encourage fusion.
So fusion is still a decade away at least, but we understand the science much more completely now. We know the problems (well a bunch of them) and it is mostly now a very difficult engineering problem rather a problem of understanding the science.
