Freight emissions management has entered the deep-water zone. This study evaluated road freight emissions from supply chain perspective using China's 2007, 2010 and 2012 multiregional input-output table. For the first time, we quantified road freight emission based on sectors in China. Heavy industries, mining, agriculture and light industry contributed 71%,14%, 12% and 3% of total NO emissions in 2012 from production perspective. Construction was the largest consumption sector (43%) responsible for road freight emission from consumption perspective. Upstream transport and final product transport emitted 3.04 Tg (80%) and 0.77 Tg (20%) NO in 2012. Huge disparities of road freight emissions flows and allocation patterns were found across provinces in China in terms of resource endowments, geographical position and economic development. The road freight emission increased rapidly from 2007 to 2012, and economic growth effect outpaced emission control effect caused by emission standard upgrade and thus dominated the emission growth. The production structure and consumption pattern changes also promoted the emission growth. It is thus important to mitigate freight emissions with different strategies based on a certain sector's freight emissions features from the whole supply chain.
货运排放管理已进入深水区。本研究从供应链的角度出发，利用中国 2007 年、2010 年和 2012 年的多区域投入产出表，评估了道路货运排放。我们首次基于中国的各行业量化了道路货运排放。重工业、采矿业、农业和轻工业对 2012 年生产源 NO 排放的贡献分别为 71%、14%、12%和 3%。从消费角度来看，建筑业是最大的消费部门（43%），导致了道路货运排放。2012 年上游运输和最终产品运输排放了 3.04Tg（80%）和 0.77Tg（20%）的 NO。考虑到资源禀赋、地理位置和经济发展等因素，中国各省之间的货运排放流量和分配模式存在巨大差异。2007 年至 2012 年，道路货运排放量迅速增加，排放标准升级带来的排放控制效应被经济增长效应所超越，从而导致排放增长。生产结构和消费模式的变化也促进了排放的增长。因此，根据整个供应链中某个部门的货运排放特征，采取不同的策略来减轻货运排放非常重要。
