本論文は、CDPデータを用いて世界中の都市の交通施策を分析。791都市のうち42%が交通に関する施策を報告しておらず、13%は電化のみであることが判明。Avoid-Shift施策を多く実施する都市ほどCDPのAリストに選ばれる傾向があり、政策の安定性や市民参加が重要であることをインタビューから導出。
English
Analyzing CDP data from 791 cities worldwide, this study finds that 42% reported no transport actions and 13% only vehicle electrification. Cities implementing more Avoid-Shift measures are more likely to earn CDP A-list status. Interviews with 16 cities reveal that policy stability, political commitment, and public engagement are crucial for reducing car dependency.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではEV推進が進むが、自動車依存度を下げる施策（Avoid-Shift）の重要性を示す。日本の都市がCDPに報告する際の参考となり、SSBJや統合報告書における交通関連の情報開示にも示唆を与える。
In the global GX context
This study provides a global benchmark for urban transport decarbonization beyond electrification. It highlights the role of CDP disclosure in tracking city climate action and offers evidence for policymakers to prioritize Avoid-Shift measures, relevant to TCFD/ISSB frameworks for cities and investors.
👥 読者別の含意
🔬研究者:Provides empirical evidence on the gap between climate goals and local transport actions, and identifies institutional factors for successful car reduction.
🏢実務担当者:City transport planners can use findings to advocate for policy stability and public engagement in implementing Avoid-Shift measures.
🏛政策担当者:Emphasizes the need for national and local policies that go beyond EV subsidies to reduce car dependency, and the value of disclosure platforms like CDP.
📄 Abstract（原文）
A transition to electric vehicles will reduce carbon emissions but risks leaving the 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 of A-S measures 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.
