日本語

本研究は、ドイツを事例に、グリーンボンド、金融の深度、金融安定性が環境質に与える影響を分析。技術普及と再生可能エネルギーが環境改善に寄与する一方、金融の深度拡大や不安定性、都市化は環境圧力を増大させることを示した。また、再生可能エネルギー環境クズネツ曲線(RKC)の転換点が従来のEKCより早期に生じることを確認。

English

This study examines the role of green bonds, financial depth, and financial stability on environmental quality in Germany (1990-2020). Findings show that technological diffusion, green bonds, and renewable energy improve environmental quality, while financial depth, instability, and urbanization increase pressure. The Renewable Environmental Kuznets Curve (RKC) turning point occurs earlier than the traditional EKC.

日本のGX文脈において

ドイツの事例ではあるが、グリーンボンドの有効性を示す実証結果は日本のグリーンファイナンス推進にも示唆を与える。特に、SSBJや有報でのグリーンボンド発行開示が増える中、その環境効果を定量的に捉える手法として参考になる。

In the global GX context

This paper provides empirical evidence linking green bonds and renewable energy to emissions reductions, supporting the global push for transition finance. While Germany-specific, the STIRPAT model extension and EKC/RKC comparison offer methodological insights for international disclosure frameworks (ISSB, CSRD) assessing financial sector impacts.

👥 読者別の含意

🔬研究者:Provides empirical validation of the Renewable Environmental Kuznets Curve and the role of green bonds in decoupling growth from emissions.

🏢実務担当者:Highlights how green bonds can serve as effective financial instruments for corporate renewable energy investments and emissions reduction.

🏛政策担当者:Demonstrates that promoting green bonds and technological diffusion accelerates the low-carbon transition, relevant for national green finance strategies.

📄 Abstract(原文)

ABSTRACT The current study aims to introduce a systematic approach to understanding the key role of the financial sector in environmental quality. To resolve the uncertainty, this study selects three financial proxies—green bonds, financial depth, and financial stability—in the case of Germany, spanning from 1990 to 2020. It deliberates the economic complexity index, urbanisation, technical diffusion and renewable energy consumption (REC) as environmental factors to extend the STIRPAT model. The investigated outcomes demonstrate a supportive role for technical diffusion, green bonds, and renewable energy in promoting environmental sustainability. The empirical analysis reveals that technological diffusion and renewable energy contribute significantly to improving environmental quality in Germany. At the same time, increasing financial depth, financial instability and urbanisation tend to increase environmental pressure. Furthermore, the financial sector, particularly through green bonds, is an effective transmission channel linking renewable energy financing to emissions reductions. The findings highlight the importance of promoting technological diffusion and strengthening green finance mechanisms to support Germany's transition to a low‐carbon economy. This empirical research work aims to revisit the Environmental Kuznets Curve (EKC) and the Renewable Environmental Kuznets Curve (RKC). It validates that the turning point of the RKC occurs earlier than that of the EKC. The adoption of green financial activities and the utilisation of renewable energy are highly recommended to achieve the desired level of sustainability.
