ブラジル主要紙G1とエスタダンが2020年1月〜2023年6月に掲載したグリーン水素関連記事286本を、BERTopicと教師ありLDAで分析。報道は資金調達・投資・生産コスト・規制・輸出機会を優先する一方、社会的アクセス、環境影響、領土紛争、水・土地利用の分配問題は周辺的だった。グリーン水素は包括的な社会生態学的転換ではなく、市場志向・輸出主導の機会として描かれがちだと示す。
English
Analyzing 286 Brazilian newspaper articles (G1, Estadão; Jan 2020–Jun 2023) with BERTopic and supervised LDA, this study finds green hydrogen coverage prioritized financing, investment, production costs, regulation, and exports. Social accessibility, environmental impacts, territorial conflicts, and distributive water/land issues remained marginal. Brazilian media framed green hydrogen as a market- and export-driven opportunity rather than a comprehensive socio-ecological transition, revealing limits of mainstream framing and weak attention to energy and climate justice.

日本のGX文脈において
日本では水素は国家戦略・GX推進の柱であり、本論文はメディア・ナラティブが政策正当性をどう形成するかを示す。日本企業が輸出市場としてブラジル水素に関与する際、社会・環境・分配面の論点を見落とすリスクを読者に喚起する。
In the global GX context
As green hydrogen becomes central to national transition strategies worldwide, this paper shows how media framing shapes legitimacy and can crowd out social and environmental dimensions. It offers a methodological template (topic modeling of media) for examining disclosure and narrative gaps relevant to ISSB/CSRD-era stakeholders assessing transition credibility.

🏢実務担当者:ブラジル水素輸出に関わる企業は、社会・環境・分配面の評価が報道・世論で不足しがちな点をリスク認識に組み込むべき。
🏛政策担当者:水素戦略の広報・政策コミュニケーションで、社会アクセスや環境正義の論点を意図的に補う必要性を示す。
📄 Abstract（原文）
ABSTRACT Media discourses help shape the visibility and legitimacy of energy transition pathways in the public sphere. This study examines how Brazilian mainstream newspapers framed green hydrogen and assesses the alignment of these narratives with the energy trilemma: energy security, environmental sustainability, and social accessibility. We analyzed 286 articles published by G1 and Estadão between January 2020 and June 2023, combining BERTopic‐based topic modeling, supervised LDA, and qualitative contextual interpretation. The findings show that media coverage addressed all dimensions of the energy trilemma but prioritized financing, investment, production costs, regulation, and export opportunities. Social accessibility, environmental impacts, territorial conflicts, and the distributive implications of water and land use remained comparatively marginal. Brazilian media therefore tended to portray green hydrogen as a market‐oriented and export‐driven opportunity rather than as a comprehensive socio‐ecological transition. These findings highlight the limits of mainstream media framing and its insufficient attention to energy and climate justice. Related Articles Kerrouche, N., and C.
