CBO Says Cap and Trade Won't Generate Revenue

from the CBO's report on the Cap and Trade tax:

CBO and the Joint Committee on Taxation (JCT) estimate that over the 2010-2019 period enacting this legislation would:
• Increase federal revenues by about $846 billion; and
• Increase direct spending by about $821 billion.
In total, those changes would reduce budget deficits (or increase future surpluses) by about $24 billion over the 2010-2019 period.
In addition, assuming appropriation of the necessary amounts, CBO estimates that implementing H.R. 2454 would increase discretionary spending by about $50 billion over the 2010-2019 period.

Let me get this right: Cap and Trade will result in a net increase in spending of $26 billion. So if the carbon emissions bill won't reduce carbon emission, won't increase revenue to the government, and will increase spending, why pass it? One thing is for certain: it will cost Americans a lot more money out of pocket! It's about power and control, not revenue or improving the environment!
