本研究は、運輸部門に焦点を当て、2030年までの気候目標達成可能性を評価。PyCaretライブラリを用いて複数の時系列モデル（ARIMA、AdaBoost、Theta forecaster等）を比較し、将来のCO2排出量を予測。貿易フローデータから貨物輸送モーダル排出量を分析し、K-Meansクラスタリングで国を分類。ギリシャとイタリアのみが目標達成軌道にあり、他国は緊急の政策改革が必要。
English
This study assesses the attainability of 2030 climate targets for selected countries, focusing on the transport sector. Using PyCaret, it trains and compares time series models (ARIMA, AdaBoost, Theta forecaster) to forecast CO2 emissions. It analyzes freight modal emissions via trade flow data and groups countries with K-Means clustering. Findings show only Greece and Italy are on track; others need urgent policy reform for low-emission freight transport.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文はEU加盟国を中心に運輸部門の排出削減目標達成可能性を評価しており、日本の運輸部門の脱炭素政策にも示唆を与える。特に貿易フローデータを用いた貨物輸送のモーダルシフト分析は、日本国内の物流効率化政策に応用可能。
In the global GX context
This paper provides a data-driven assessment of transport sector decarbonization against EU Green Deal targets, offering machine learning forecasting and modal shift analysis. The finding that only two EU countries are on track underscores the global challenge in transport decarbonization, making it relevant for international climate policy and corporate logistics strategy.
👥 読者別の含意
🔬研究者:Focus on the machine learning forecasting methodology and country clustering approach for transport emission analysis.
🏢実務担当者:Use the data-driven mitigation strategies for freight modal shift in corporate logistics planning.
🏛政策担当者:Note the urgency of policy reform in transport sector to meet 2030 targets, especially for countries not on track.
📄 Abstract（原文）
Policymakers are increasingly calling for tangible actions to meet the United Nations targets for reducing emissions to 1990s levels. This study assesses whether climate targets are attainable by 2030 for a selected set of countries, with a particular focus on the transportation sector. PyCaret’s Python library is used to train and compare a range of time series models and derive transport emission forecasts of countries up to 2030. We employ a range of machine learning models, including ARIMA, AdaBoost, and Theta forecaster, using historical transport emissions data to forecast CO2 emissions and assess the likelihood of countries achieving the EU Green Deal’s decarbonization objectives. To further support policy design, we analyze freight modal emissions using trade flow data and group countries using the K-Means clustering based on their emission profiles. Our findings show that only two countries—Greece and Italy—are currently on track to meet the 2030 targets. The remaining nations require urgent and targeted policy reform, particularly in shifting freight transport toward lower-emission modes. We conclude by offering realistic, data-driven mitigation strategies for those unlikely to meet their commitments.
