国际贸易将货物消费与相关的环境影响分开，包括农业和土地使用变化产生的温室气体排放（统称为“土地使用排放”）。通过使用新的排放估计和多区域投入产出模型，我们评估了2004年至2017年全球贸易中体现的土地使用排放。每年，27%的土地使用排放和22%的农业用地与农产品有关，这些农产品最终在不同的地区消费。约四分之三的隐含排放来自土地利用变化，其中最大的转移来自巴西、印度尼西亚和阿根廷等低收入国家向欧洲、美国和中国等工业化程度较高的地区。因此，减少全球土地使用排放和可持续发展可能取决于提高供应链的透明度。
International trade separates consumption of goods from related environmental impacts, including greenhouse gas emissions from agriculture and land-use change (together referred to as "land-use emissions"). Through use of new emissions estimates and a multiregional input-output model, we evaluated land-use emissions embodied in global trade from 2004 to 2017. Annually, 27% of land-use emissions and 22% of agricultural land are related to agricultural products ultimately consumed in a different region from where they were produced. Roughly three-quarters of embodied emissions are from land-use change, with the largest transfers from lower-income countries such as Brazil, Indonesia, and Argentina to more industrialized regions such as Europe, the United States, and China. Mitigation of global land-use emissions and sustainable development may thus depend on improving the transparency of supply chains.
