I said, "one-tenth or smaller than that of the US"
I don't have exact figures, I expect some are more and most less than that. The point is that a fair allocation of emissions would be on a per-capita basis, not a simple reduction from everyone's 1990 levels.
FWIW, I think the per-capita limit should be allocated proportionately to 1980 population levels, when global warming theory was obviously correct - and migrants take their allocation with them.
