湖北碳交易试点价格稳定机制、评估及启示

碳排放交易体系存在诸多影响配额供需两端的因素,为避免配额供需严重失衡和碳价格剧烈波动,湖北碳交易试点建立了一套系统的碳价格稳定机制。这套机制包括配额分类管理及注销机制、企业配额事后调节机制、配额投放和回购机制、碳价格涨跌幅限制机制,对湖北碳交易试点的平稳运行发挥了积极作用。本文对上述机制进行了分析评估,并据此提出了全国碳交易体系建设中建立碳价格稳定机制的政策建议。

Evaluation on carbon price stabilization mechanism of Hubei ETS pilot and its policy implications

There are many factors that can influence the demand and supply of allowances in carbon emission trading system. To avoid a severe unbalance between demand and supply of allowances or an excessive fluctuation of carbon price, the Hubei ETS pilot set up a systematic carbon price stabilization mechanism, including classified allowance management, automatic cancellation, ex-post adjustment, allowance reserve and price limit, which has been exerting positive effects. In conclusion, attention should be paid on carbon price stabilization mechanism in the establishment of the national carbon trading system.
