All this, says Miss Browner, would complement Mr Obama's broader ambition to tackle global warming through a cap-and-trade scheme, whereby the government would set steadily declining annual limits on emissions, and would then auction permits to pollute up to that level.

Browner表示，所有的这些行动都有助于奥巴马实现其雄心壮志，即通过限额交易体系解决全球变暖的问题。由此，政府会要求限额污染排放量逐年下降，并对达到这一水平的污染拍卖许可证。
