The Time Path and Implementation of Carbon Sequestration
构建动态模型研究碳排放、封存和碳存量的最优时间路径，提出三种将碳封存引入碳交易市场的机制，并评估其效率。
We develop a dynamic model to investigate the optimal time paths of carbon emissions, sequestration, and the carbon stock. We show that carbon sinks should be utilized as early as possible, and carbon flow into sinks should last until the atmospheric carbon concentration is stabilized. We rule out any cyclical patterns of carbon sequestration and release. We propose and assess three mechanisms to efficiently introduce sequestration into a carbon permit trading market: a pay-as-you-go system, a variable-length-contract system and a carbon annuity account system. Although the three mechanisms may not be equally feasible to implement, they are all efficient.
