Carbon risk and corporate creditworthiness: Evidence from a major emerging economy
研究了印度非金融企业的碳排放与信用度之间的关系，发现高排放显著增加市场隐含违约概率，且巴黎协定后关联更强，财务实力和ESG实践可缓解此风险。
We examine the relationship between climate-related transition risk and the creditworthiness of non-financial Indian firms. We find that higher emissions are associated with significantly higher market-implied probabilities of default (PD), and that this association becomes stronger after the Paris Agreement. Firms misaligned with Paris-consistent decarbonization pathways and those with greater exposure to prospective carbon pricing exhibit elevated credit risk. The magnitude of the association varies with firm characteristics: stronger financial positions, robust ESG practices, and higher investment capacity attenuate the positive association between emissions and PD. Reputational exposure and the cost of equity emerge as significant channels linking emissions to default risk, whereas no meaningful effect is detected through the cost of debt. These results highlight the growing importance of transition risk in emerging markets and highlight mechanisms through which investors incorporate firm-level environmental exposure into credit risk assessments.
