本研究は、炭素税や排出権取引（ETS）などの炭素価格付けが持続可能な投資を促進する役割を検証する。世界銀行とGSIAのデータを用いて2012年から2022年までの炭素価格収入と持続可能な投資額の推移を分析し、両者の間に強い時間的相関があることを示した。炭素価格収入は3.53億ドルから14.2億ドルへ、持続可能な投資は13.3兆ドルから30.3兆ドルへ増加した。ただし、因果関係の立証には至っていない。
English
This study examines how carbon pricing mechanisms (carbon taxes and ETS) can promote sustainable investment. Using World Bank and GSIA data from 2012-2022, it finds a strong temporal correlation between carbon pricing revenues and sustainable investment growth: revenues rose from $353M to $1.42B, while sustainable investment increased from $13.3T to $30.3T. However, causality is not established due to aggregated data and descriptive methods.

日本のGX文脈において
日本ではカーボンプライシング（GX-ETS、化石燃料賦課金）が導入されつつあり、本研究成果は日本の排出量取引制度が持続可能な投資を呼び込む可能性を示唆する。SSBJ開示やGX投資促進策との整合性を検討する上で参考になる。
In the global GX context
Globally, this paper provides empirical evidence linking carbon pricing to sustainable investment growth, supporting the case for coordinated carbon pricing policies as catalysts for transition finance. It aligns with ISSB and CSRD frameworks that emphasize the role of policy signals in redirecting capital.

📄 Abstract（原文）
This research examines how carbon pricing mechanisms can help in enhancing the level of sustainable investments. Initially, carbon pricing through carbon taxes and emissions trading systems (ETS) was supposed to internalize the external costs of GHG emissions, thus changing the investment incentives, leading to lower transition risk, and promoting investments in low-carbon projects. The study uses data from the World Bank Carbon Pricing Dashboard and the Global Sustainable Investment Alliance (GSIA) and tracks globally the trends from 2012 to 2022 regarding carbon pricing revenues, average carbon prices, total amounts of sustainable investments, and their modifications. The results demonstrate that there is a great correlation over time between the expansion of carbon pricing and sustainable investments. In 2012, carbon pricing revenues totaled about $353 million, while in 2022 they reached $1.42 billion. At the same time, total sustainable investment increased from $13.3 trillion to $30.3 trillion in the same period. The elements of sustainable investment changed as well as ESG integration, corporate engagement, positive screening, and sustainability-themed investments became popular. The evidence suggests that carbon pricing may enhance the credibility of the policies, create revenue sources for green investments, and re-direct the capital to the low-carbon economy. However, the study does not establish causality due to its aggregated global data and descriptive methodology. The findings therefore support coordinated and appropriately designed carbon pricing policies as a potential catalyst for sustainable finance.
