This study presents novel insights on modelling the implications of voluntary climate-related information disclosure on corporate green innovation (GI) in China. Based on a constructed dataset of 13,664 firm-year observations between 2014 and 2020, we quantify climate-related disclosures under the Task Force on Climate-Related Financial Disclosures framework using computerized text analysis. Our findings show that climate-related information disclosure substantially bolsters corporate green innovation after addressing endogeneity concerns. However, the promoting effects vary drastically across industry attributes, ownership structure, and environmental regulations. Further channel analysis demonstrates that “greenwashing” behaviours and financial constraints adversely moderate the nexus between climate-related information disclosure and green innovation of firms, while digital finance positively moderates it. Overall, this study enriches the literature and offers practical implications for firms engaging in the green innovation process more effectively under a more transparent environment-related disclosure system.
