本研究は、二酸化炭素除去（CDR）技術に対する市民の関与を促進するため、オンラインでの熟議グループを用いた模擬的協議プロセスを実施した。その結果、熟議によって5つのCDRオプションのうち陸上バイオエネルギー炭素回収貯留（BECCS）の評価が向上し、「わからない」という回答が71%減少した。また、参加者の評価に対する自信が全般的に高まった。熟議の内容分析では、有効性や実現可能性、意図せざる結果への関心が示され、規模や気候目標との関連性への注目は限定的だった。
English
This study simulates a consultation process using online deliberation groups in Norway to assess public engagement with carbon dioxide removal (CDR) technologies. Deliberation significantly improved assessments of land-based bioenergy carbon capture and storage (BECCS) by 0.29 steps on a 1-4 scale and reduced 'don't know' responses by 71%, while confidence in assessments increased broadly. Analysis of transcripts shows participants focused on effectiveness, feasibility, and unintended consequences, with less attention to scale and climate targets.

📄 Abstract（原文）
Abstract Carbon dioxide removal (CDR) plays an important role in climate scenarios, and multiple CDR research and development efforts are ongoing. For instrumental, substantive and normative reasons, the public should be involved in decision-making related to CDR. We simulate a consultation process using online deliberation groups based on random draws from the Norwegian population, bookended by surveys. Using a multi-mode approach, we find that deliberation substantially affects enhances participants’ assessment of land-based bioenergy carbon capture and storage by .29 steps on a 1-4 scaleonly one of the five marine and terrestrial CDR options presented, compared to a control group, while causing no significant changes in the assessments of four other CDR options presented. At the same time, the deliberation treatment reduces the incidence of “don’t know” and “no opinion” responses by 71% for the main questions about the five technologies. However, it broadly increases participants’ confidence in their assessments and their views on climate change. Analysis of deliberation transcripts shows that participants emphasize the effectiveness, feasibility, and potential for unintended consequences of CDR, whereas questions of scale and relations with climate targets receive little attention. We conclude with observations on how deliberative formats may be used and enhanced as a research approach and procedure for involving the public in formulation of net-zero policy.
