国际贸易引起了温室气体和污染气体在国家间的转移，且转移排放量及其占国家排放总量的比重逐年增加。因此，是否应在气候变化历史责任归因和减排政策制定中考虑转移排放的影响，在国际社会上引起了剧烈的争议。然而，已有的研究一方面受限于时间较短、种类单一的转移排放清单，另一方面缺乏对转移排放引起的气候和环境变化问题的定量评估。鉴于以上问题，本项目拟构建长时间序列的、涵盖了多种温室气体和污染气体的转移排放国家清单。在此基础上，利用地球系统模式CESM定量评估温室气体转移排放对气候变化历史责任归因和京都议定书减缓效果的影响。最后，利用耦合了大气化学模块的大气环流模式CAM5初步探讨污染气体转移排放对大气环境的可能影响。本项目的开展有助于丰富和拓展国际转移排放清单，在一定程度上减少目前国际气候谈判中对于排放计量系统的争议，同时为减排政策和污染防治方案的制定提供参考。

International trade results in the transfers of greenhouse and pollution gases among countries, and the transfer amount and its proportion on nation's total emissions show a significant increase in recent decades. Thus, it is vigorously debated whether transfer emissions should be taken into account when attributing responsibility for historical climate change and formulating emissions reduction policy. However, existing transfer emissions inventories include only CO2 and has short time span; and quantitative assessment of the role of transfer emissions in climate change and atmospheric environment has not been performed yet. Therefore, this project aims to construct a long-time series of transfer emissions inventories containing important greenhouse and pollution gases. Next, using an earth system model CESM, we investigate the role of transfered greenhouse gases in attribution of historical responsibility and the effect of Kyoto Protocol. Furthermore, we explore possible influence of transfered pollution gases in atmospheric environment with CAM5. This project is beneficial for (i) enriching and expanding transfer emissions inventories, (ii) partially resolving the dispute on emission measurement system in international climate negotiations, and (iii) providing a reference for formulation of emissions reduction policy and pollution control plan.
