Using Sino‐Securities Environmental, social, and governance (ESG) ratings data, we examine how environmental uncertainty affects the ESG performance of Chinese A‐share non‐financial listed firms from 2008 to 2020. Our findings show that environmental uncertainty harms corporate ESG performance. In particular, when environmental uncertainty increases, a firm's ESG score and ESG ratings decline due to factors such as financial constraints and industry competition. We argue that as the environmental risk premium rises, it increases the real options value of postponing sustainable investment for a firm. Consequently, the firms tend to cut down their ESG investment by weighing the long‐term benefits and short‐term direct costs. The value of real options changes with the investment opportunities available to the firms and the financing constraints and competitive pressure changes the size of investment opportunities. We argue that higher financing constraints and industry competition restrict available investment opportunities and dilute the negative impact of environmental uncertainty on corporate ESG performance. These results add to the existing literature investigating the impact of uncertainty on corporate ESG performance and offer insights to regulators and enterprise managers. These results are robust to alternate proxies of ESG performance and alternate regression techniques.

Policy uncertainty (PU), and sustainability disclosure, influence the performance of the firms. We use European data to extend the nascent literature on sustainability disclosure, and economic policy uncertainty by investigating the moderating impact of sustainability disclosure on the relationship between economic policy uncertainty and firm performance. We find overwhelming evidence that policy uncertainty reduces firm performance; however, sustainability disclosure moderates this destructing impact of policy uncertainty on firm performance. Our results show that environmental and social disclosure by the European firms enhances their reputation and help these firms in reducing the policy-induced uncertainty. A higher governance disclosure representing efficient corporate governance also help European firms to moderate the negative effect of policy uncertainty on their performance. Our results are robust to alternate proxies of firm performance as well as endogeneity issues.

While extending the scarce literature on determinants of corporate social responsibility (CSR) decoupling, we examine the impact of CEO power on CSR decoupling. Using panel data of US firms for 2002–2017, we find that CEO power increases CSR decoupling. Our results remain consistent after controlling for the endogeneity problem. Aligned with the managerial power theory, our results suggest that firms with powerful CEOs are more likely to manage CSR performance through decoupling.
