For example, unlike the World Trade Organization, whose dispute-settlement mechanism imposes penalties for abandoning negotiated reductions of trade barriers, the targets for emission reductions are not binding and enforceable commitments. The US has not agreed to accept such sanctions for failing to meet emissions targets; but, without penalties, the exercise is largely futile and only encourages cynicism about the effort to combat climate change.
比如，与世界贸易组织不同——世贸组织的争端解决机制可以对拒不执行商定的减少贸易壁垒措施的行为施以惩罚——排放削减并不具有约束性，也没有强制性义务。美国不同意和不接受因达不到排放目标而受到制裁；但是，没有惩罚机制，排放削减要求就是无用功，只会激起人们对对抗气候变化努力的冷嘲热讽。
