Globalization has characterized geo-economic integrations of world regions via South-South, North-North, and South-North trades, which play a critical role in displacing global greenhouse gas emissions. Based on the global CH emission inventories from the EDGAR database and the global multi-region input-output accounts from the EORA database, this study explores the trade-induced CH emission transfers of 20 geographical regions of the world from 1990 to 2015. Global total CH emissions increased by 19.13% in 2015 compared to 1990, while trade-related emissions increased by 46.28% over the same period. Western Europe, the USA, Japan, Other East Asia, and Mainland China were the largest five importers of embodied CH emissions, while Sub-Saharan Africa, Russia, Middle East, Mainland China, and Southeast Asia were the largest five export regions of embodied CH emissions. Substantial agriculture- and energy-related CH emissions were transferred from developed regions to developing regions. The trade between economies from the global south and the global north had undergone positive changes, with the trade structure and transfer path showing a trend of divergence. Among the total CH emissions embodied in international trade, the CH emissions embodied in South-North trade accounted for more than half (55.94-62.72 Tg, 71%-55%) from 1990 to 2015. The CH emissions embodied in the South-South trade accounted for 19%-34% (14.62-39.46 Tg), and the proportion of CH emissions embodied in the North-North trade appeared to be relatively small (10%-11%, 8.05-12.82 Tg) during the period. It is imperative to strengthen South-South, South-North, and North-North cooperation in multilateral trade to jointly cut down the CH emissions among world regions.
全球化通过南南、北北和南北贸易实现了世界各区域的地缘经济一体化，这些贸易在转移全球温室气体排放方面发挥了关键作用。本研究基于 EDGAR 数据库的全球 CH 排放清单和 EORA 数据库的全球多区域投入产出账户，探讨了 1990 年至 2015 年世界 20 个地理区域的贸易引起的 CH 排放转移。与 1990 年相比，2015 年全球总 CH 排放量增加了 19.13%，同期与贸易相关的排放量增加了 46.28%。西欧、美国、日本、其他东亚和中国大陆是最大的五个 CH 排放体进口地区，而撒哈拉以南非洲、俄罗斯、中东、中国大陆和东南亚是最大的五个 CH 排放体出口地区。大量与农业和能源相关的 CH 排放从发达地区转移到发展中地区。全球南方和北方经济体之间的贸易发生了积极变化，贸易结构和转移路径呈现出分化的趋势。在国际贸易中包含的总 CH 排放量中，1990 年至 2015 年期间，南南贸易中包含的 CH 排放量占一半以上（55.94-62.72 Tg，71%-55%）。南南贸易中包含的 CH 排放量占 19%-34%（14.62-39.46 Tg），而北北贸易中包含的 CH 排放量比例似乎相对较小（10%-11%，8.05-12.82 Tg）。加强南南、南北和北北多边贸易合作，共同削减世界各区域的 CH 排放量至关重要。
