Audio Today, Obama insisted that (in the future?), this system would cost the taxpayer 'A postage stamp a day' So... which is it? Also, if the big polluters can just buy credits, how will that reduce emissions? If they can't afford to retrofit (or don't want to) and credits are cheaper, they'll just buy credits. If credits cost more than retrofitting, then this will effectively put a company out of business if it can't make the cut=- thereby reducing competition and putting greater power in the hands of few, larger companies- the ones who are most likely to find a way around this anyway, while passing costs onto the consumer. How is this supposed to work, exactly?
