生产和服务由固定资本支持，需要大量的物质投资。由于材料使用会引发大量的碳排放，因此通过固定资本形成对材料使用和碳排放进行管理对于实现气候目标至关重要。在这里，我们计算了2015年日本经济的资本包含的材料足迹（MFs）及其引起的碳排放。结果表明，固定资本形成占家庭消费总MF的1 / 3，占4.54亿吨MF。服务业形成的固定资本总量为1.68亿吨，在9个固定资本类别中碳强度较高。我们的研究结果强调，需要打破对服务业固定资本形成的刺激，以抑制材料使用和碳排放。为此目的，公司的材料使用需要管理到范围3，特别注意第2类（固定资本）。
Production and services are supported by fixed-capital which require large amounts of material investments. Given that material use triggers substantial carbon emissions, management of the material use and carbon emissions via fixed-capital formation is vital for climate targets. Here, we calculate capital-embodied material footprints (MFs) and their induced carbon emissions for the 2015 Japanese economy. Our results show that the fixed-capital formation was responsible for 454 million tons MF, or one-third of the total MF regarding household consumption. The fixed-capital formation for the service sector produced an MF of 168 million tons and had a high level carbon intensity among the nine fixed-capital groups. Our findings underscore the need to break the stimulus to fixed-capital formation in the service industries to curb material use and carbon emissions. To this end, material use in companies needs to be managed up to Scope 3, with particular attention paid to Category 2 (fixed-capital).
