日本語
UNITA大学連合の12大学のホームページの炭素フットプリントをWebsite Carbon Calculatorで監査。1ページ閲覧あたり0.08〜2.38g CO2eと大きな差があり、評価はB〜F。5機関がグリーンホスティングを利用。再測定で結果の安定性を確認し、差異は電力網よりウェブデザインとホスティング選択に起因することを示唆。
English
This study audits the carbon footprints of 12 UNITA alliance university homepages using the Website Carbon Calculator. Emissions range from 0.08 to 2.38 g CO2e per page view, with grades from B to F. Five institutions use green hosting. Repeated measurements confirm stability, and differences are attributed to design and hosting choices rather than national grids.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の大学や企業のウェブサイト運営においても、デジタル炭素フットプリントの可視化はESG情報開示の一部として注目され得る。SSBJ開示では直接対象外だが、サステナビリティ報告での自主的な取り組み事例として参考になる。
In the global GX context
This study extends digital carbon footprint auditing to a multi-country university alliance, offering a replicable methodology for institutions worldwide. It highlights the role of web design and hosting in reducing emissions, which can inform sustainability reporting and green IT strategies under frameworks like CSRD.
👥 読者別の含意
🔬研究者:Provides a validated methodology for comparative website carbon auditing across institutions.
🏢実務担当者:Offers actionable insights for reducing website carbon footprints through design and hosting choices.
🏛政策担当者:Suggests potential for coordinated digital sustainability standards in university alliances.
📄 Abstract（原文）
Higher education institutions increasingly rely on digital infrastructures, but these systems also contribute to carbon emissions through their digital carbon footprint. Institutional websites are an important part of this footprint, serving both as sources of emissions and as platforms for communicating sustainability initiatives. This study evaluates the carbon footprints of the homepages of the 12 member and associate university websites of the UNITA Universitas Montium Alliance, a European Universities Initiative focused on digital transformation and sustainability. Using the Website Carbon Calculator (v4), an audit conducted in June 2026 measured CO2e emissions per page view, estimated annual emissions under standardized traffic, hosting energy use, and the number of trees required to offset emissions. Results showed considerable variation, with ratings ranging from B to F and emissions between 0.08 and 2.38 g CO2e per page view. Five institutions already use green hosting. The same 12 homepages were re-measured under an identical protocol on 20 July and 17 August 2026; eleven returned identical values in all three rounds and the twelfth varied by 0.05 g CO2e per page view. These findings extend a technical carbon-footprint auditing methodology previously validated only within single-country university systems to a comparative, multi-country alliance setting, and are consistent with website design and hosting choices, not national electricity grids, playing the dominant role in the observed differences between institutions. For UNITA, this points to a concrete opportunity to coordinate action through its existing Green Sustainability and Virtual Campus work packages, aligning the alliance’s digital infrastructure with the sustainability standards it already promotes elsewhere.
