本研究は、道路輸送の温室効果ガス排出削減に向け、ASIF（Activity-Structure-Intensity-Fuel）手法を高速道路コンセッションのScope 3排出管理に適用する枠組みを初めて提案する。ブラジルの主要高速道路のデータを用い、フリーフロー料金や車両電化などの介入シナリオを評価し、排出削減を契約指標に変換できることを示した。フリーフロー料金導入により料金所排出を最大37%削減できると推定。

This study proposes a novel framework applying the ASIF methodology to manage Scope 3 emissions in highway concessions, using data from a major Brazilian highway. It shows that interventions like free-flow tolling and fleet electrification can reduce emissions and be translated into contractual indicators. Free-flow tolling reduced toll plaza emissions by up to 37%.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、SSBJ開示や有報でのScope 3算定が進む中、インフラ事業における排出削減を契約に組み込む手法は参考になる。高速道路会社やPFI事業者にとって、排出削減目標を契約指標に組み込む実践的枠組みとして示唆に富む。
In the global GX context
This paper offers a practical framework for integrating Scope 3 mitigation into concession contracts, relevant to global infrastructure governance and climate regulation. It provides a method to link emissions estimation with contractual performance, useful for policymakers and infrastructure operators worldwide.

📄 Abstract（原文）
Road transport is a major contributor to greenhouse gas (GHG) emissions, representing a significant challenge when it comes to achieving climate goals. Although methodologies such as Activity–Structure–Intensity–Fuel (ASIF) are widely used to estimate transport emissions, their application as regulatory instruments remains unexplored. This study addresses this gap by proposing a framework that operationalizes ASIF for managing Scope 3 emissions in toll-road concessions. Using operational and traffic data from a major Brazilian highway concession, baseline emissions are compared with intervention scenarios involving the adoption of initiatives such as free-flow tolling and fleet electrification. The results demonstrate that emission reductions can be associated with specific ASIF components and can be translated into measurable contractual indicators. In the case study, the implementation of free-flow tolling reduced emissions at toll plazas by up to 37%. Fleet electrification, which is now limited by the charging capacity of roads, can be improved and have its effects captured by the framework so that actions resulting from the concessions made to improve availability can enable policies aimed at reducing total user-related emissions. The study is the first, to the best of the authors’ knowledge, to operationalize the ASIF methodology as a governance and contractual instrument for Scope 3 emissions management in highway concessions in Brazil. By bridging emissions estimation and concession governance, it provides a practical framework for incorporating Scope 3 mitigation targets into concession contracts and climate-oriented transport regulation.
