本研究は、道路輸送サービスにおける温室効果ガス（GHG）排出量の計算と報告に焦点を当て、EN 16258とISO 14083の2つの基準を比較した。スロバキアの道路貨物輸送ルートのケーススタディを通じて、両基準および選択した排出計算ツールを用いて排出量を計算し、結果を比較した。その結果、両基準は同等の総排出量を示すものの、排出係数の構造や間接排出の扱いにおいて差異があることが明らかになった。ISO 14083はより包括的で詳細なアプローチを提供するが、データ利用可能性や方法論の複雑さが導入の障壁となっている。
English
This study compares two greenhouse gas (GHG) emission calculation standards for road transport services: EN 16258 and ISO 14083. Using a case study of a Slovak road freight route, emissions were calculated under both standards and with selected calculators. Results show comparable total emissions, but discrepancies in emission factor structures and inclusion of indirect emissions. ISO 14083 offers a more comprehensive approach, yet its adoption is hindered by data availability and methodological complexity.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業がSSBJや有報でスコープ3排出量を報告する際、輸送セクターの算定基準としてISO 14083が重要となる。本論文のスロバキアでの実施課題は、日本での導入にあたっても参考になりうる。
In the global GX context
As companies align with ISSB/TCFD requirements, standardizing transport GHG accounting is critical. This paper highlights practical challenges in transitioning from EN 16258 to ISO 14083, offering insights for global disclosure frameworks.

📄 Abstract（原文）
Greenhouse gas (GHG) emissions from transport represent a significant environmental challenge, increasing the need for standardized calculation and reporting methodologies. This study aims to analyze and compare the approaches to GHG emissions calculation under EN 16258 and ISO 14083, for road transport services, and to discuss implementation challenges related to the transition to the new standard in the Slovak transport sector. The research is based on a case study of a model road freight transport route, in which emissions are calculated using both standards and selected emission calculators, and the results are compared. The results indicate that both methodologies yield comparable total emission values, with discrepancies arising mainly from the structure of emission factors and the inclusion of indirect emissions. ISO 14083 demonstrates a more comprehensive and detailed approach, particularly in the consideration of energy supply processes. The analysis also reveals discrepancies between emission calculators due to differences in input data, emission factor databases, and modeling approaches. The findings suggest that although awareness of ISO 14083 is increasing, its wider implementation is limited by data availability, methodological complexity, and varying levels of sector readiness.
