2011年12月在南非德班举行的联合国气候谈判的结果，为建立一个国际气候政策架构提供了一个重要的新机会，该架构能够以合理的成本提供广泛的国际参与和显著的全球二氧化碳减排。我们评估了后德班时代潜在气候政策架构的一个重要组成部分：温室气体独立可交易许可制度之间的联系。由于联系降低了实现特定目标的成本，因此将现有和计划中的限额与交易制度联系起来的压力很大，事实上，一些联系已经或即将存在。我们借鉴了最近的政治和经济经验，评估了联系在德班之后的国际气候政策中可能发挥的潜在作用，包括短期的、事实上的区域、国家和次国家限额与交易体系之间间接联系的架构，以及长期的、更全面的自下而上的直接联系架构。虽然这种联系肯定有助于降低长期减排成本，但它也可以作为建立体制和政治结构的有效机制，以支持未来的气候协议。
The outcome of the December 2011 United Nations climate negotiations in Durban, South Africa, provides an important new opportunity to move toward an international climate policy architecture that is capable of delivering broad international participation and significant global CO2 emissions reductions at reasonable cost. We evaluate one important component of potential climate policy architecture for the post-Durban era: links among independent tradable permit systems for greenhouse gases. Because linkage reduces the cost of achieving given targets, there is tremendous pressure to link existing and planned cap-and-trade systems, and in fact, a number of links already or will soon exist. We draw on recent political and economic experience with linkage to evaluate potential roles that linkage may play in post-Durban international climate policy, both in a near-term, de facto architecture of indirect links between regional, national, and sub-national cap-and-trade systems, and in longer-term, more comprehensive bottom-up architecture of direct links. Although linkage will certainly help to reduce long-term abatement costs, it may also serve as an effective mechanism for building institutional and political structure to support a future climate agreement.
