アイルランドのBEV購入補助金（€3,500固定）を対象に、2025年1月実施のサーベイを用いて、参照車両との比較で実現されるエネルギー・炭素削減量を推計する研究。電源炭素係数や走行距離の行動変化を考慮し、人口セグメント別に削減効果の分布を分析。補助金のターゲティング変更により、より公平かつ大きな削減が可能かを検討する。

This study uses a January 2025 survey to quantify the energy and carbon savings from Ireland's fixed €3,500 BEV purchase grant relative to a reference vehicle. It accounts for grid carbon intensity and behavioural changes in annual mileage, and compares savings across Irish population segments. The analysis explores whether a retargeted grant scheme could deliver greater or fairer decarbonisation outcomes.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもEV購入補助金（CEV補助金）の費用対効果や公平性が議論されており、補助金ターゲティングの設計手法は日本の政策担当者にとって参考になる。ただし、日本のGX開示制度（SSBJ等）との直接的な接点は乏しい。
In the global GX context
As governments worldwide phase down EV subsidies, this paper offers a methodology for evaluating the distributional and carbon-effectiveness of grant targeting. It contributes to the global policy debate on efficient decarbonisation incentives, though it does not directly address disclosure frameworks like TCFD or ISSB.
👥 読者別の含意
🔬研究者:Provides a survey-based framework for estimating medium-term carbon savings from EV subsidies, incorporating behavioural and grid factors.
🏢実務担当者:Highlights how subsidy design affects EV market demand and could inform corporate fleet electrification strategies.
🏛政策担当者:Offers evidence on the distributional fairness and carbon efficiency of EV grants, useful for redesigning subsidy schemes.
📄 Abstract（原文）
Extended abstract 6-191-26 The decarbonisation of Ireland’s passenger vehicle fleet is a key component of its strategy to meet its climate targets. Since 2017, Ireland’s EV grants have provided an added incentive to new vehicle purchasers to choose an electric vehicle, with the grant restricted to full Battery-Electric Vehicles (BEVs) since 2022. The grant amount is fixed at €3500 for passenger vehicles valued between €14,000 and €60,000. While grant-aided BEVs are expected to decarbonise transport in the long-run, the carbon savings in the medium term depend critically on the emissions expected from a reference vehicle, on the carbon factor for electricity used to charge the BEVs, and on any behavioural responses, such as driving a BEV for more, or fewer, kilometres per year than the reference vehicle would have been driven. This paper presents the results of a survey carried out in January 2025, with supplemental data to be collected in 2026, to interrogate each of those aspects of new BEV purchase, when compared to a reference new vehicle. The analysis will quantify the implied energy and carbon savings and compare the implied energy and carbon savings for different segments of the Irish population. The results will provide insights on the distribution of those potential savings, on the fair – or unfair – distribution of those savings, and on the potential for a modified grant scheme to achieve greater or more fairly distributed savings through targeting.
