就算我们可以提高企业支付碳排放的价格，并且推广它们到各个企业，碳税或者碳排放与交易的手段仍然难以快速地减少人类需要缓和温室效应而减少的碳排放量。

Even if we can get the prices up, and apply them more generally, carbon taxes or cap and trade strategies alone are unlikely to be sufficient to quickly induce the reductions we need.

尽管联邦的碳排放总量管制与排放交易系统可能会是一个冒险，但我们可以考察一下这一理念在各州是如何发挥作用的，有很多州的作法已经遥遥领先于华盛顿。

Though a federal cap-and-trade system for carbon would largely be a foray into the unknown, we can examine how the idea is working in the states, many of which are far ahead of Washington.

这虽然与降低碳排放无关，但是却对包含碳排放限额交易的法案通过不无帮助。

This has nothing to do with reducing carbon emissions, but it might help a bill that does contain carbon caps to pass.
