人工光合成によるソーラー燃料について、ドイツの一般市民のリスク認知を初めて体系的に定量化した研究。メンタルモデル面接（N=24）と確認調査（N=292）により、生産プロセスと燃料製品それぞれの認知リスクを分類した。生産段階では自然・技術・生物・経済・人口・政治・医療の全リスク類型が出現し主にリスク転嫁、製品段階ではリスク相殺の傾向。事故・産業独占・価格負担性が主要懸念で、安全基準や公的資金への懸念は低かった。
English
First systematic mapping of lay risk perceptions of solar fuels from artificial photosynthesis in Germany, using mental model interviews (N=24) and a confirmatory survey (N=292). Production-phase risks spanned all typologies and mostly involved risk transfers, while product risks involved offsets. Top concerns were accidents, industrial monopolies, and affordability; safety standards and public funding drew least concern. Findings stress integrating societal risk perception into communication and governance for acceptance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもグリーン水素・CCU・バイオものづくりを組み合わせた次世代燃料の社会実装が政策課題となる中、専門家評価に偏りがちなリスク評価に市民認知を組み込む視点は、SSBJ開示やトランジション戦略における社会的受容性・ステークホルダー対話の設計に示唆を与える。
In the global GX context
As global decarbonization moves toward novel fuel pathways combining green hydrogen, CCU, and engineered organisms, this study shows that public risk perception—not just expert probability/impact—shapes legitimacy and deployment. It adds a societal-acceptance dimension relevant to transition governance and non-financial disclosure of emerging technologies under TCFD/CSRD-style frameworks.

📄 Abstract（原文）
Mitigating climate change requires societal transformation, including decarbonization innovations, as CO 2 emissions remain the primary driver of global warming. One emerging solution is solar fuels, produced through artificial photosynthesis by integrating green hydrogen, carbon capture and utilization, and engineered microorganisms. While solar fuels offer a pathway for reusing CO 2 and reducing fossil resource dependency, they also generate new risks, uncertainties, and complex risk-risk tradeoffs. Traditional risk assessments rely on expert judgments of probability and impact, overlooking public risk perceptions shaped by personal values and experience. Yet these lay perceptions are critical for public acceptance of sustainable technologies: neglecting them risks public resistance, legitimacy deficits, and implementation failure. This study is the first to systematically map and quantify lay risk perceptions of solar fuels. We used mental model interviews ( N = 24) to map and categorize laypeople's perceived risks associated with (1) the solar fuel production process and (2) the resulting fuel product. Perceived risks were categorized using established typologies of risk types and risk-risk tradeoffs. A confirmatory survey ( N = 292) quantified perceived salience of these risks. Results indicated that production spanned all categories (natural, technological, biological, economic, demographic, political, and medical risks), while product risks excluded natural ones. Production risks mostly entailed risk transfers, while product risks entailed risk offsets. Key concerns included accidents, industrial monopolies, and affordability. Lowest concerns included safety standards and public funding. Our findings highlight the importance of integrating societal risk perceptions into communication and governance, as they represent critical preconditions for societal acceptance.
