化学产品在现代社会中无处不在。化工行业是最大的工业能源消耗者和第三大二氧化碳排放者。目前化工行业的缓解方案组合强调上游的“供应方”解决方案，而下游的缓解方案，如材料效率，相对较少受到重视。造成这种情况的主要原因是，有关该行业物资流动的数据稀缺，以及该行业复杂的供应链高度交织在一起。我们提供最新、全面和透明的公开数据集，涵盖化工行业的新生产路线：从化石燃料原料到化工产品。我们通过复杂的转化过程网络绘制2013年全球质量流图，并考虑到二次反应物和副产物，我们始终保持完全的质量平衡。由此产生的数据集部分解决了化学行业供应链公开信息匮乏的问题，并可用于确定下游缓解方案的优先次序。
Chemical products are ubiquitous in modern society. The chemical sector is the largest industrial energy consumer and the third largest industrial emitter of carbon dioxide. The current portfolio of mitigation options for the chemical sector emphasizes upstream "supply side" solutions, whereas downstream mitigation options, such as material efficiency, are given comparatively short shrift. Key reasons for this are the scarcity of data on the sector's material flows, and the highly intertwined nature of its complex supply chains. We provide the most up to date, comprehensive and transparent data set available publicly, on virgin production routes in the chemical sector: from fossil fuel feedstocks to chemical products. We map global mass flows for the year 2013 through a complex network of transformation processes, and by taking account of secondary reactants and by-products, we maintain a full mass balance throughout. The resulting data set partially addresses the dearth of publicly available information on the chemical sector's supply chain, and can be used to prioritise downstream mitigation options.
