日本語
本論文は、分子・プロセス設計からサプライチェーン、惑星限界に至る統合ツールチェーンを提案する。計算支援型分子・プロセス設計、時間明示的LCA、転換経路最適化、絶対的持続可能性評価の4本柱を組み合わせる。実験室では持続可能に見える分子が産業規模で環境ボトルネックを生む「後悔すべき代替」を早期に回避できると主張する。
English
This vision paper proposes an integrated toolchain spanning molecular and process design, supply chains, and planetary boundaries. It combines computer-aided molecular/process design, time-explicit LCA, transition pathway optimization, and absolute sustainability assessment. The framework helps chemists anticipate macro-level consequences of micro-level design choices early, avoiding regrettable substitutions that appear sustainable in the lab but create industrial-scale environmental bottlenecks.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では化学・素材産業がScope3排出の大部分を占め、SSBJや有報でのサプライチェーン排出開示が進む。本ツールチェーンは、素材設計段階から絶対的持続可能性を組み込む考え方を示し、日本企業のLCA高度化やScope3削減戦略に示唆を与える。
In the global GX context
Globally, this aligns with the shift from relative to absolute sustainability assessment and the growing demand for Scope 3 and product-level disclosure under ISSB/CSRD. It offers a methodological bridge between early-stage chemical design and planetary-boundary-aligned transition pathways, relevant to transition finance and net-zero target setting.

📄 Abstract（原文）
Chemists want to design molecules and catalysts that are environmentally sustainable. But whether a new molecule is sustainable does not depend on its structure and reaction alone. It depends on the system built around it: the reactor and separation steps used at scale, the utilities supplying them such as electricity and high-temperature heat, the supply chains delivering feedstocks and products, and how all of this fits into a pathway towards a future net-zero circular economy that stays within the safe operating space of the planet. We present the vision of an integrated toolchain that spans these scales, from molecular design to planetary boundaries. The toolchain combines four pillars: (i) computer-aided molecular and process design [1] to identify promising candidate molecules and their most efficient industrial synthesis routes, (ii) time-explicit life cycle assessment [2] to evaluate environmental impacts dynamically by accounting for evolving future production systems, (iii) transition pathway optimization [3] for strategic deployment planning and the design of robust, long-term supply chain networks, and (iv) absolute sustainability assessment [4], which evaluates system-wide environmental impacts against the planetary boundary framework to ensure future pathways do not transgress ecological limits. By equipping chemists with an accessible yet comprehensive framework, this toolchain bridges the gap between molecular design and systems engineering. Researchers can anticipate the macro-level consequences of micro-level design choices early in development, avoiding regrettable substitutions where a molecule appears sustainable in the lab but creates severe environmental bottlenecks at industrial scale.
