本論文は、国民勘定データを用いたマクロレベルの炭素フロー分析手法を提案し、オランダを事例に11の製品カテゴリと12の転換部門間の炭素フローを可視化した。結果、オランダ経済は炭素の輸入・輸出に強く依存し、供給の80%以上が化石由来であり、2050年の気候中立・完全循環型目標達成には大幅な転換が必要とされる。
English
This paper presents a novel macro-level carbon flow mapping method using national accounts data, applied to the Netherlands with 11 product categories and 12 transformation sectors. Results show heavy reliance on carbon imports/exports and over 80% fossil-based supply, highlighting the urgent need for a shift to circular carbon to meet 2050 climate neutrality and full circularity targets.

📄 Abstract（原文）
Abstract Carbon is a fundamental component of our economy, as well as a key element of greenhouse gas emissions. Tracking carbon flows captures energy, material, and climate impacts, and enables a direct examination of the link between material and energy transitions, indicating progress towards circular carbon and the net-zero target. This study presents a novel method for mapping carbon flows at the macro level using national accounts data, while also enabling granular analysis of carbon flows across different sectors. The analysis examined carbon flows across 11 main product flow categories and 7 subcategories, mapping them by source and destination, and across 12 transformation sectors. Applied to the Netherlands as a case study, the results reveal that the Dutch economy strongly relies on imports and exports of carbon, with net imports accounting for 131 Mt C yr −1 (82% of total carbon supply) and net exports for 89 Mt C yr −1 (83% of total carbon demand) in the year 2020. Furthermore, over 80% of the carbon supply is fossil-based. Therefore, to meet the Dutch government’s 2050 targets of climate neutrality and full circularity, i.e. relying solely on biogenic and other circular carbon sources, significant shifts in carbon supply and demand are urgently needed.
