服务业通常被认为是“绿色”的，因为它们的直接排放量很小;然而，它们占世界国内生产总值的65%，占2019年全球贸易总额的20%以上。本文对2010年至2018年服务贸易碳排放量的变化进行了量化，并确定了全球和区域范围内碳排放变化的驱动因素。从全球南方出口的隐含排放量的年增长率（2.0%）是全球北方（1.0%）的两倍，贸易结构不同。基于双边贸易伙伴关系和年增长率，我们进一步确定了全球南方服务出口的三种贸易模式。根据服务贸易的特点和地区间贸易结构的差异，提出了三种具体的减排政策。研究结果提供了目前缺乏的量化证据，对政策决策至关重要。
Service industries are generally considered "green'' because of their marginal direct emissions; however, they account for 65% of the world gross domestic product and over 20% of total global trade in 2019. Here, we quantify the evolution of carbon emissions embodied in services trade from 2010 to 2018 and identify the driving factors of emission change at the global and regional scales. The annual growth rate of embodied emissions exported from the Global South (2.0%) is double that of the Global North (1.0%), with a different trade structure. We further identify three trade patterns of service export in the Global South based on the bilateral trade partnership and annual growth rate. Three kinds of specific emission mitigation policies are proposed based on the characters of services trade and different trade structures between different regions. The results provide quantitative evidence currently lacking and critical to policy decision making.
