《京都议定书》的签订是国际合作解决气候变暖的典范，它对发达国家提出了强制减排要求，发展中国家不受到强制性要求。由于减排会对一国的工业造成较大影响并损害该国的国际贸易，以美国为代表的发达国家提出了“碳关税”，旨在通过对高耗能产品征收一定额度的碳排放税从而达到环境保护以及贸易保护的目的。本文运用实证的方法对美国征收碳关税对我国塑料制品出口造成的影响进行了分析，结果显示：如果美国征收30美元/吨，会造成我国塑料制品出口价格上升0.43%，并最终导致2015年出口减少0.52%；如果美国征收60美元/吨，将会导致出口价格上涨0.87%，出口总额下降1.04%。为了有效地避免碳关税对我国高碳产品出口的冲击，笔者提出了调整能源消费结构和进行碳排放的国际转移等建议。

The signing of the Kyoto protocol is a model of international cooperation to solve the climate problem; it puts forward to developed countries cutting requirements. Due to the industrial emissions reduction will cause significant impact on the country's international trade, the United States as a representative of the developed countries puts forward to "carbon tariffs", aiming to achieve the purposes of environmental protection and trade protection. In this paper, the author analyzes the carbon tariffs’ impact on China's plastic products export. The results showed that: if the United States levies $30 / ton, it can cause our country plastic products export prices to rose 0.43%, and finally cause exporting in 2015 to reduce 0.52%; if the United States levy $60 / ton, and it will lead to exporting prices rose 0.87%, finally exporting falls 1.04%. In order to avoid this predicament, the author puts forward some suggestions, including the energy consumption structure’s adjustment and carbon emissions’ international transformation.
