摘要
国际碳排放权交易是在应对全球气候变化过程中提出的以成本最小化方式实现污染排放控制的环境政策机制。目前,中国主要通过清洁发展机制(CDM)来参与国际碳交易,并出口相应的核证减排量。CDM项目在我国发展迅速,出口的核证减排量呈显著上升态势,然而本文认为,当前CDM项目的开发并不是越多越好。因为碳减排的空间是有限的,考虑未来减排压力和减排成本的增加,当前碳排放权的出口量存在最优规模问题。本文通过建立两阶段最优化模型,对这一问题进行了详细讨论。在此基础上结合当前国际碳交易现状,指出了中国参与其中遭遇的问题与相应启示。
International carbon emission entitlements trading is the least-cost environment policy to cope with global climate change.Currently,China connects itself with international carbon exchange mainly by clear development mechanism (CDM).CDM is developing very fast in our country,and the certified emission reductions of export are getting more and more.However,CDM items should not be developed as many as possible.As the carbon reduction capacity is limited,there exits optimal export scale in current carbon emissions trading,considering the increasing emission reduction pressure.Through setting two-stage optimal model,the paper analyses this issue in detail.After that,it analyses the unfair problems when China joining international carbon trade,and gives some suggestions for the future.
