ABSTRACT

The material footprint (raw material consumption) was proposed as a basis for monitoring SDGs 8.4 and 12.2. However, there is no institutionalized procedure providing globally consistent national material footprints. The OECD aims to institutionalize the material footprint through the development of one official inter-country input–output (ICIO) database applicable for its calculation. Inherent to input–output analysis is the aggregation error, which may impair the results. Therefore, in the case of the EU I analyze the aggregation error which can be expected if NACE rev2 classification is utilized for this ICIO database, and investigate the most important disaggregations, depending on the desired focus of the results. I conclude that the disaggregation level should reflect the intended purpose of the RME indicators. For their deeper analysis, and determination of strategies for their decrease, I conclude that NACE rev2 classification is inappropriate, and recommend high disaggregation and utilization of hybrid units.

摘要

提议将材料足迹（原材料消耗）作为监测可持续发展目标 8.4 和 12.2 的基础。然而，没有提供全球一致的国家物质足迹的制度化程序。经合组织旨在通过开发一个适用于其计算的官方国家间投入产出 (ICIO) 数据库将物质足迹制度化。输入-输出分析固有的是聚合误差，这可能会损害结果。因此，在欧盟的情况下，我分析了如果 NACE rev2 分类用于该 ICIO 数据库时可以预期的聚合错误，并根据结果的期望重点调查最重要的分类。我的结论是，分解级别应该反映 RME 指标的预期目的。为了他们更深入的分析，
