This paper empirically examines the impact of managerial climate attention on corporate carbon emissions and related mechanisms using panel data of Chinese A-share listed companies. It is found that managerial climate attention significantly negatively impacts corporate carbon emissions. The mechanism analysis shows managerial climate attention can reduce carbon emissions by promoting corporate green innovation. Managerial myopia, investor concern, and corporate governance capabilities can moderate the impact of managerial climate attention. Our results demonstrate that managerial climate attention can be an internal driver for corporate carbon emission reduction. This study provides good theoretical and empirical evidence for corporate climate governance.
