碳税与许可证交易的对比分析

A Comparison between Carbon Taxes and Tradable Permits

随着经济的发展,我国二氧化碳(CO2)的排放量不断增加,减排的压力不断增大。而在众多的减排CO2的方法中,较为常用的是征收碳税(Carbon taxes)和许可证交易(tradable permits)。虽然两者都具有市场效率的经济措施,但在有效性、不确定性和公平性方面的表现却各有优劣。综合来看,我国应当将完善碳税作为一个重要选择。

With the development of economy, the amount of carbon emission （C02） is increasing, thus greater pressure in decreasing the emission. The two most common ways to achieve this is to tax carbon taxation and practice tradable permits. Although both economic measures have market effectiveness, differences in efficiency, uncertainty and equality remain. Generally, improving carbon taxes is considered as an important choice.
