Global Governance Implications of Green Credit: Empirical Evidence of Environmental Performance Improvement among China's Heavily Polluting Enterprises

Global Governance Implications of Green Credit: Empirical Evidence of Environmental Performance Improvement in Chinese High-Polluting Enterprises

Over the past two decades, green credit has gradually evolved from a marginal innovative tool into a core policy lever for global environmental governance. From the European Union's Sustainable Finance Action Plan to clean energy banks in the United States, governments have attempted to internalize environmental externalities by redirecting capital flows. However, the debate over whether green credit can genuinely improve corporate environmental performance—especially in highly polluting industries—has never subsided in academia or policy circles. A new study published in *Humanities and Social Sciences Communications* provides rigorous empirical evidence on this issue, using panel data from Chinese A-share listed companies from 2006 to 2022.

Research Interpretation: The Quantitative Effects of Policy Intervention

The study employs a difference-in-differences (DID) approach, using Bloomberg ESG environmental scores as a proxy for corporate environmental performance, to examine the policy effects of the 2012 Green Credit Guidelines issued by the China Banking Regulatory Commission (CBRC). The results show that the green credit policy significantly increased the environmental scores of highly polluting firms by 2.3 to 3.7 points. According to Bloomberg's calibration, this improvement translates to a reduction of 1.2 to 1.8 million tonnes of sulfur dioxide emissions per year, equivalent to 15% to 22% of China's medium-term emission reduction targets for 2020–2025. These figures not only validate the effectiveness of the policy but also reveal the unique role of financial regulation in environmental governance.

Mechanism Analysis: Financing Constraints and Innovation Offsetting

The study further identifies two key mechanisms: financing constraints and innovation offsetting. On the one hand, green credit raises the financing threshold for highly polluting enterprises, forcing projects that rely on external capital expansion to reassess environmental risks. On the other hand, in order to obtain credit support, firms have to increase R&D in green technologies, using innovation to hedge against financing pressures. This dual pathway, combining both "crowding-out" and "incentive" effects, resembles a market-based "prodding" mechanism, and its effects are far more enduring than simple administrative penalties. Notably, this is not simply a withdrawal of capital; rather, through the transmission of financial signals, it alters firms' long-term investment decisions.

Heterogeneity Findings: Institutional Foundations and Policy Effectiveness

The heterogeneous effects of the policy are equally noteworthy. The study shows that firms in the eastern region, firms in competitive industries, and state-owned enterprises exhibited more pronounced environmental performance improvements. The eastern region has more mature financial markets and stricter environmental enforcement, making green credit more binding. Firms in competitive industries face survival pressures and are more inclined to gain competitive advantages through green innovation. State-owned enterprises, owing to their policy responsiveness and resource allocation capabilities, are better able to translate compliance requirements into actual environmental investment. These differences imply that green credit is not a one-size-fits-all universal tool; its effectiveness depends on the match between the institutional environment and corporate structure.

Global Implications: Southern Countries and the ESG WaveChina's experience with green credit is particularly instructive for Global South countries. Many developing economies are in the midst of industrialization and face environmental pressures similar to those China experienced earlier. Traditionally, they have worried that environmental regulation would weaken economic growth potential, but Chinese evidence shows that green credit can force industrial upgrading through financial channels, avoiding the old path of "pollute first, clean up later." At the same time, the rising global wave of ESG investment is changing the logic of capital allocation. Institutional investors are paying increasing attention to corporate environmental footprints, which complements green credit. When public financial policy and the ESG preferences of private capital markets exert force in the same direction, the pressure on high-polluting enterprises to transform will be multiplicative.

However, we must also avoid excessive optimism. The effectiveness of green credit depends on a set of preconditions: clear environmental information disclosure standards, an effective enforcement system, and sufficiently deep financial markets. In regions with weak institutions, green credit may degenerate into a tool for "greenwashing" rather than substantive governance reform. Furthermore, policymakers also need to pay attention to distributional effects—heterogeneous outcomes suggest that some enterprises may be eliminated by the market due to financing obstacles. How to ensure the transition of workers in affected enterprises is the core proposition of a just transition.

Conclusion: The Co-Evolution of Financial Instruments and Governance

At present, the world faces the dual challenges of climate crisis and biodiversity loss, and green finance is placed under high expectations. The Chinese case shows that well-designed green credit policies can become an effective lever for promoting the transformation of high-polluting enterprises, but their success is not to be taken for granted. The international community needs to think at a deeper level about the synergy between financial instruments and governance systems, incorporating environmental performance into financial risk pricing while leaving buffer space for the most vulnerable enterprises and communities. Only in this way can green finance truly serve the long-term sustainable development agenda, rather than becoming yet another financial illusion.
