Climate change is an ethical and moral challenge of a global scale due to its potentially catastrophic implications for human welfare. Understanding forces that drive corporate adaptation to climate change is an important research topic in business ethics. In this paper, we propose that shareholder climate-related proposals could be a catalyst for corporate innovations in technologies mitigating climate change. Our results, based on the analysis of US firms, indicate that corporations respond positively to these proposals by producing more climate-related patents (...) and citations. We also uncover potential casual channels of influence. Further, we find that corporate governance moderates the documented effects. These proposals lead to a more efficient and valuable innovation output, but lower firm performance in the short term. The real effect that shareholder proposals have on innovation gains clarity in the context of climate change, contributing to the discussion of investor “voice.”. (shrink)
