[quote name='mykevermin']so it's essentially the same idea used for pollution credits, then, only applied to CO2 emissions?
Eh, well, I'm kinda on the ambivalent path of "you're in absolute denial if you don't believe in global warming, but you're loud and angry and pro-corporation, which means you'll win in the end, so go right ahead mr and mrs free-market flag waving dipshits, vote to hasten the end of life on this planet so you can keep your job making those plastic containers for "Lunchables" you no-good no-long-term-vision having sons a bitches," so whatever, I guess.
We should all drive Bigfoot trucks. And you know Big Macs tasted so much better in styrofoam containers. Bring 'em back.
Me me me, my my my. Seven generations?

It is the same idea applied to CO2 emissions, correct. There are some fundamental differences, though.
Actual pollution, when this idea was implemented (such as SO2), was able to be cleaned up because there were technologies available to do so (they were just expensive). So it made some sense to force costs to where the pollution-controlling scrubbers and the like were made to be used by polluters. As someone who feels the air we breathe is a commonly owned resource, I have no problem with the government protecting our common property from companies exploiting it at the expense of our health.
CO2, OTOH, is emitted by just about every economic activity, not to mention every animal on earth, including humans. There is no proven way to "capture" or "scrub" CO2 emissions from things like coal or gas power plants ("carbon sequestration" is a developing technology at best at this point, and an expensive one at least in the near future). Also, it's simple for whole industries to pull up the stakes and move to China/India/Mexico/wherever if they are subject to cap-and-trade, which is exactly what is predicted will happen. In fact, the estimate I pointed to above (0.1 degree C reduction by 2100) doesn't take into account that many people believe worldwide emissions will actually INCREASE due to cap-and-trade as CO2-intensive industries, such as cement making, move to China or elsewhere (as happened in the EU when they implemented a similar policy).
So leaving the science aside, this is a stupid policy. Hell, many environmental groups, such as Greenpeace, are against it because it does virtually nothing to stop CO2 emissions. What cap-and-trade really amounts to is a huge giveaway to moneyed interests who have successfully lobbied for free CO2 credits, which they could then resell at 100% profit (minus the lobbying costs, I guess).
