スリランカの小規模ホテルを対象に、GHGプロトコルとISO 14064に準拠して12カ月間のカーボンフットプリントを算定した研究。総排出量は649,979 kg CO₂-eqで、冷媒ガス由来のScope 1が77.22%を占めた。低GWP冷媒への転換、緑化屋根・クールルーフ、太陽光発電、LPG最適化、食品廃棄物管理を削減策として提示している。
English
This study quantifies the carbon footprint of a small-scale hotel in Sri Lanka over 12 months following GHG Protocol and ISO 14064. Total emissions reached 649,979 kg CO2-eq, with Scope 1 refrigerants (R-32, R-22) accounting for 77.22%. It proposes mitigation pathways including low-GWP refrigerants, green/cool roofs, solar PV under net metering, LPG optimization, and food waste management.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準や有報でのScope 3開示が進む中、中小規模事業者にとって実務的な算定例として参考になる。特に冷媒由来のScope 1が支配的なケースは、サービス業の脱炭素戦略を考える上で示唆に富む。
In the global GX context
While global disclosure frameworks (ISSB, CSRD) increasingly mandate Scope 3 reporting, this paper offers a granular, sector-specific example from the hospitality industry in a developing economy. It highlights the often-overlooked dominance of refrigerant emissions in service-sector footprints, relevant to TCFD-aligned transition planning.
👥 読者別の含意
🔬研究者:GHGプロトコルに基づく小規模事業者の算定事例として、Scope 1冷媒排出の重要性を定量的に示す。
🏢実務担当者:ホテル・サービス業の実務者が自社のカーボンフットプリントを算定し、冷媒管理や再エネ導入の優先順位を検討する際の参考になる。
🏛政策担当者:中小規模事業者向けの脱炭素支援策や、冷媒規制の強化を検討する際のエビデンスとして活用できる。
📄 Abstract(原文)
The hospitality sector is a significant contributor to global greenhouse gas (GHG) emissions due to its energy-intensive operations. This study quantifies the carbon footprint of a small-scale hotel in Sri Lanka, identifies major emission sources, and proposes mitigation pathways toward sustainable hospitality. It was conducted over 12 months from January 2025 to December 2025. A comprehensive assessment was conducted in accordance with the GHG Protocol and ISO 14064 guidelines, encompassing direct (Scope 1), indirect (Scope 2), and value chain-related (Scope 3) emissions. The total carbon footprint was estimated at 649,979 kg CO₂-eq, with Scope 1 emissions, primarily from refrigerant gases in air-conditioning systems (R-32 and R-22), constituting 77.22% of total emissions. Scope 3 emissions, including transportation of staff and food waste management, accounted for 12.55%, while Scope 2 emissions from grid electricity contributed 10.57%. Mitigation strategies, including transitioning to low-Global Warming Potential (GWP) refrigerants, enhancing energy efficiency through green roofs and cool roofs, adopting solar photovoltaic systems under Net Metering, optimizing LPG consumption, and improving food waste management, were identified as effective measures to reduce the hotel’s carbon footprint. This study provides a critical benchmark for operational sustainability, offering actionable insights for hotel managers, policymakers, and the tourism sector to align hospitality operations with climate action and Sustainable Development Goals.
