English
This study forecasts carbon emissions trading prices using four factors: stock market, exchange rate, international energy commodity prices, and international carbon prices. LASSO confirms all factors matter; among RF, XGBoost, BP neural network, and SVR, random forest performs best. The method aids policymakers, regulators, and investors in carbon markets.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではGXリーグや東証カーボン・クレジット市場が始動し、炭素価格の予測・評価は企業の内部炭素価格設定や投資判断に直結する。SSBJ開示や移行金融の文脈でも、炭素価格シナリオの精緻化は日本企業の戦略立案に資する。
In the global GX context
As carbon markets expand under EU ETS, CBAM, and emerging Asian schemes, robust price forecasting supports TCFD/ISSB scenario analysis and transition-finance valuation. The ML comparison adds methodological evidence for internal carbon pricing and market-risk modeling in disclosure practice.
👥 読者別の含意

📄 Abstract(原文)
The prediction of the prices in carbon emissions trading is a complicated issue. Carbon prices are affected by various factors such as macroeconomics, market emotions, and climate policy. Non-linearity, non-stationarity, and multi-frequencies are among the features of the carbon prices. Now, there is little carbon emissions trading price history data available, and a large number of affecting factors are present; hence, a prediction model should be established by considering all factors fully. First, we made the analysis of carbon emission trading price's affecting factors. Four factors are considered in our research. They are the stock market factor, international exchange rate factor, international energy commodity price factor, and international carbon emissions trading price factor. Through the use of LASSO algorithm, we have concluded that all the above factors have important impacts on carbon prices. Then, we used four methods to predict the prices of carbon emissions trading. They are random forest (RF), xgboost, back propagation (BP) neural network, and support vector regression (SVR). It turns out that RF model performs better than the other three models in predicting the carbon emissions prices. This methodology will be helpful for policymakers, market regulators, and investors who are involved in the carbon emissions trading mechanism.
