It's 17% under ACESA and 20% out of the committee, but that is under the cap. My organization has estimated that with the other provisions that are not capped, you would get between 27% and 32% reductions by 2020. So the capped portion would get you 17%. Those sources that are not capped but yet subject to regulations of one type or another could actually lead to emission reductions between 27% and 32%.
