Sustainability performance, executive compensation, market value, and say-on-pay voting adoption: evidence from the STOXX Europe 600

PurposeThis study aims to investigate the link between carbon emissions and market value for nonfinancial companies in the STOXX Europe 600 index, with a specific focus on the moderating effect of executive compensation.Design/methodology/approachTo achieve the study's purpose, this study uses data from the STOXX Europe 600 index between 2010 and 2021. The researchers use ordinary least squares regression analysis to examine the relationship between carbon emissions and market value while taking into account the moderating effect of executive compensation. The study also uses additional tests, such as the dynamic two-step system generalized method of moments regression and the difference in differences method.FindingsThe study reveals four key findings. First, there is a statistically significant negative relationship between carbon emissions and market value. Second, executive compensation has a negative moderating effect on the association between carbon emissions and market value. Third, Say-on-Pay regulations can encourage companies to adopt environmentally responsible practices, which can positively impact their market value. Finally, the study shows that the Paris Agreement motivates companies to prioritize sustainability, leading to potentially higher market values for those that are more environmentally responsible.Practical implicationsThis study highlights the importance of considering environmental sustainability in corporate decision-making. It suggests that prioritizing sustainability can lead to financial benefits, as companies with lower carbon emissions tend to have higher market values. The findings also have important implications for regulators and investors.Originality/valueThis study provides novel insights into the link between carbon emissions and market value and the moderating effect of executive compensation. It also sheds light on the potential impact of Say-on-Pay regulations and the Paris Agreement on corporate sustainability practices and market values.
