日本語
本レビューは、燃料・化学品・炭酸化・コンクリート養生・EOR・バイオ製品・園芸など主要なCO2利用（CCU）経路を横断的に評価し、技術成熟度・展開障壁・ライフサイクル影響・市場性・政策枠組みを整理する。CCUは特に脱炭素困難セクターの産業脱炭素化に寄与し得るが、大規模展開にはプロセス効率改善、再エネ統合、LCA手法の精緻化、支援政策が不可欠と結論づける。
English
This review evaluates major CO2 utilization (CCU) pathways—fuels, chemicals, carbonation, concrete curing, EOR, bio-products, horticulture—covering technology status, deployment barriers, lifecycle implications, market potential, and policy frameworks. It finds CCU can support industrial decarbonization, especially in hard-to-abate sectors, but large-scale deployment requires efficiency gains, renewable energy integration, robust LCA, and supportive policy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はGX推進戦略・カーボンリサイクル政策でCCUを重点領域に位置づけ、NEDOや企業実証が進む。本レビューは実装障壁と政策要件を整理し、国内CCU事業化・LCA整備・支援制度設計の参照枠を提供する。
In the global GX context
CCU sits at the center of global industrial decarbonization debates and transition finance taxonomies (EU Taxonomy, ISSB climate disclosures). This review's mapping of barriers, LCA gaps, and policy needs informs how CCU projects are credibly disclosed and financed under TCFD/ISSB frameworks.

📄 Abstract（原文）
The ever-increasing Greenhouse Gas (GHG) emissions primarily Carbon Dioxide (CO 2 ), are adversely impacting the climate at an unprecedented rate, leading to more frequent extreme climate events. Reducing GHG and counteracting climate change can be achieved by decarbonizing energy systems and challenging the status quo of current industrial practices of producing and consuming energy. One solution to reduce the GHG impact is to separate CO 2 from flue gases and use it as a raw material for industrial processes and products. However, despite growing research activity, many CCU pathways remain limited by high energy demand, economic constraints, low technology maturity, and uncertain environmental performance. Existing literature review studies often focus primarily on conversion processes while providing limited assessment of commercialization barriers, scalability, and policy requirements for deployment. Our review evaluates major current pathways for utilizing CO 2 in diverse fields, such as fuels, chemicals, carbonation, concrete curing, tertiary oil recovery, coal bed methane recovery, bio-products, and horticulture. The study shows the technological status, deployment barriers, lifecycle implications, market potential, and policy framework associated with these pathways based on recent scientific and industrial developments. The work indicates that CCU technologies can contribute to industrial decarbonization, particularly in hard-to-abate sectors. However, large-scale deployment will require improvements in process efficiency, renewable energy integration, lifecycle assessment methodologies, and supportive policy frameworks to enhance economic competitiveness and ensure meaningful climate benefits.
