エクアドル・アンバトの文化観光イベント「果物と花の祭典」向け仮設インスタレーションのLCAを実施。総排出量は408.46 kg CO2eで、建設段階が最大（272.00 kg）を占め、次いで輸送（85.00 kg）、原材料抽出（43.96 kg）と続く。使用段階は受動的構造のためほぼゼロ、廃棄段階は7.50 kgだった。embodied carbonが主要な環境負荷であることを示し、仮設文化インフラの設計初期段階へのLCA統合の価値を強調する。
English
An LCA of a temporary cultural installation at Ecuador's Festival of Fruits and Flowers found total emissions of 408.46 kg CO2e, dominated by the construction phase (272.00 kg), followed by transport (85.00 kg) and raw material extraction (43.96 kg). The passive use phase was negligible and end-of-life added 7.50 kg. Embodied carbon is the dominant burden, underscoring the value of integrating LCA into early design of temporary cultural infrastructure.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では万博・地域祭事・観光イベントの脱炭素化が関心を集めるが、本論文は一時的構造物の炭素会計手法として参考になる。ただしSSBJ・有報・TCFD等の開示制度との直接接続はなく、実務適用は限定的。
In the global GX context
While global disclosure frameworks (TCFD/ISSB/CSRD) focus on corporate value chains, this study extends carbon accounting to ephemeral cultural infrastructure and event-based urban tourism—an under-covered Scope 3-adjacent domain. It offers a methodological template for low-carbon event management, though it does not engage disclosure standards directly.
👥 読者別の含意
🔬研究者:一時的構造物・イベントのLCA手法とembodied carbon算定のケース参照として有用。
🏢実務担当者:文化・観光イベントの企画段階で炭素負荷を把握し低炭素設計に活かす示唆を提供。
🏛政策担当者:都市観光・イベント政策に炭素評価を組み込む際の基礎的エビデンスとなりうる。
📄 Abstract（原文）
This study presents a life cycle assessment (LCA) of an ephemeral architectural installation developed for the Festival of Fruits and Flowers (FFF), a major cultural tourism event held in Ambato, Ecuador. Unlike previous LCA studies of temporary structures that primarily focus on construction performance, reusable buildings, or event infrastructure, this research examines a temporary cultural installation as part of an urban tourism and cultural heritage system. The study assessed the carbon footprint (CFP) across raw material extraction, manufacturing, transportation, construction, use, and end-of-life stages. Total emissions reached 408.46 kg CO2e, with the construction phase contributing the largest share (272.00 kg CO2e), followed by transportation (85.00 kg CO2e) and raw material extraction (43.96 kg CO2e). The use phase showed negligible emissions because the structure’s passive, while the end-of-life stage accounted for 7.50 kg CO2e. The results show that embodied carbon is the dominant environmental burden of the analyzed installation and highlight the value of integrating LCA into early design and planning for temporary cultural infrastructure. By linking quantitative carbon assessment with cultural tourism, place identity, and ephemeral heritage, this study provides a case-specific methodological reference for developing low-carbon strategies for temporary cultural installations and environmentally responsible urban events.
