Climate change poses manifold consequences to human well-being as well as ecosystems. One of the most widely accepted measures to mitigate climate risks is at the firm level, aiming to reduce carbon dioxide and innovate climate-friendly technology. However, doing so requires comprehensive factors, including legislation, the company’s strategy, and finance. Using the Bayesian Mindsponge Framework (MBF) for analyzing 178 enterprises listed in S&P 500 companies from 2016 to 2021, the current study examined how their climate risk mitigation efforts can affect their stock price. We found that emitted carbon dioxide negatively affects the stock price. In contrast, the income and mitigating strategies, including producing eco-friendly products, using renewable energy, and environmental expenditures investments, are positively associated with the increase in share value. However, the mitigation efforts are conditional on the income of the company. The results indicate that investors expect corporations to transform financial capital from the stock market into bankable, climate-resilient projects. Based on these findings, we suggest that building an eco-surplus culture by stimulating climate change knowledge can be a promising approach to promoting a corporation’s mitigation efforts.
