为实现《巴黎协定》的目标，全球社会正致力于大幅度减少温室气体排放。除了与能源有关的努力之外，通过碳捕获和储存和/或利用生物质资源防止碳排放到大气中被认为是实现全球目标所不可或缺的。在这项研究中，考虑到含碳商品作为碳库在我们的社会类似于森林和水库，使CCS，物质利用的碳流量化的投入产出为基础的物质流分析（IO-MFA）。因此，在2011年，6.3 Mt-C的石油衍生碳和7.9 Mt-C的木材衍生碳被引入日本社会作为最终用途产品（例如，汽车和建筑物）以各种形式（例如，塑料和合成橡胶）。总量（14.2 Mt-C）相当于日本2011年CO2年排放量的4.1%（52.1 Mt-CO2）。随后，通过参考可以处理报废产品中目标形态的碳的技术，针对碳的每种形态和最终用途，讨论了碳作为材料的可回收性。通过数字显示实施适当技术的必要性和潜力，这项研究为政策制定者在我们的社会中建立高质量的碳循环提供了科学指导。
To achieve the goals of Paris Agreement, global society is directing much effort in substantially reducing greenhouse gas (GHG) emissions. In addition to energy-related efforts, prevention of carbon release into the atmosphere with carbon capture and storage (CCS) and/or utilization of biomass resources is considered indispensable to achieving the global objective. In this study, considering carbon-containing goods as carbon reservoirs in our society similar to forests and reservoirs enabling CCS, the flow of materially utilized carbon was quantified by input-output-based material flow analysis (IO-MFA). As a result, in 2011, 6.3 Mt-C of petroleum-derived carbon and 7.9 Mt-C of wood-derived carbon were introduced to the Japanese society as end-use products (e.g., automobiles and constructions) in various forms (e.g., plastics and synthetic rubbers). The total amount (14.2 Mt-C) corresponded to 4.1% (52.1 Mt-CO2) of annual CO2emission in Japan in 2011. Subsequently, by referring to the technology that can treat carbon in the target forms in end-of-life products, the recoverability of carbon as a material has been discussed with respect to each form and end-use of carbon. By numerically showing the necessity and potential of implementing appropriate technologies, this study provides scientific direction for policymakers to establish a quality carbon cycle in our society.
