本論文は、CDPに報告した791都市のデータを分析し、多くの都市が自動車利用削減のための回避・転換施策を実施していないことを発見。特に、EV化のみに依存する施策では、自動車依存に伴う広範な問題が未解決のまま残るリスクを指摘。インタビュー調査から、施策の成功には政策の安定性、政治的コミットメント、市民参加が重要と示唆。
English
This study analyzes CDP data from 791 cities and finds that 42% reported no transport actions and 13% only electrification. It uses the Avoid-Shift-Improve framework to categorize cities. Interviews show that policy stability, political commitment, and public engagement are crucial for implementing car reduction measures beyond EV.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも都市の交通脱炭素化が進むが、EV補助金に偏る傾向がある。本論文は、SSBJ対応においてスコープ3の交通部門の削減を考える際、回避・転換施策の重要性を示す。日本版CDP報告においても、単なるEV化ではなく、総合的な交通政策が必要であることを示唆。
In the global GX context
Globally, cities are key for climate action. This paper highlights the gap between electrification and actual transport decarbonization, relevant for ISSB/TCFD reporting on scope 3. It shows that city-level CDP data can be used to assess policy depth beyond technology.
👥 読者別の含意
🔬研究者:This paper provides a framework to evaluate city transport policies using CDP data, useful for comparative urban climate research.
🏢実務担当者:City officials should consider the ASI framework and not rely solely on EVs for transport decarbonization.
🏛政策担当者:National policies should support cities with stable funding and long-term vision for sustainable transport.
📄 Abstract（原文）
A transition to electric vehicles will reduce carbon emissions but risks leaving wider harms associated with car dependency unresolved. Using the Avoid-Shift-Improve (ASI) Framework to analyse Carbon Disclosure Project (CDP) data we find a gap between global climate goals and local transport delivery. Of the 791 cities reporting to the CDP in 2022, 42% reported no transport actions and a further 13% reported only vehicle electrification (Improve) actions. We group cities according to reported number of Avoid or Shift (A-S) categories of action to reduce car use and ownership. Cities reporting across a higher number of A-S categories (High A-S) to avoid car trips and shift to sustainable modes were found more likely to have been awarded A-List status by the CDP for exceptional climate leadership. To explore the self-reported CDP data further we interviewed senior transport practitioners working in 16 cities across high, medium and low A-S categories. Insights from interviews suggest that policy stability, political commitment to climate action and public engagement support implementation of more car reduction measures. Officers in High A-S cities associate successful implementation with durable sustainable transport policies and communication of the co-benefits of reducing car use. In contrast, officers in Low A-S cities describe challenges with policy volatility, lack of resources for engagement, and single benefit framing e.g. to address air pollution or congestion. These findings suggest that reducing car dependency in cities requires more than technological substitution and may depend on institutional capacity, policy continuity and public engagement.
