Are gender and cultural diversities on board related to corporate CO2 emissions?

This paper aims to explore whether the female share on the boards of directors of companies influences CO2 emissions in both developed and emerging markets. Furthermore, the influence of cultural diversity on the board of directors on CO2 emissions is analysed. A sample of companies belonging to the MSCI and MSCI Emerging Market indices in Europe over ten years (2010–2019) was analysed using regression models with panel data. The results demonstrate that in both developed and developing markets, the ratio of women to men on the board of directors is inversely related to the company's CO2 emissions, which support legitimacy theory in two aspects: it fulfils the right to equality and non-discrimination for women, and it also reduces CO2 emissions. In general, cultural diversity had a negative influence on CO2 emissions. This research is relevant for policymakers and managers seeking to improve sustainability and equality policies in companies. If gender equality in corporate monitoring roles is environmentally beneficial for the planet, legislators will support quota policies. In addition, shareholders will have an incentive to implement gender equality policies, as they will legitimise the company in the eyes of society, which has economic benefits. On a practical level, this work will contribute to achieving gender equality in corporate governance and improve the understanding of factors influencing CO2 emissions to the environment. This study contributes to previous research since it is the first time that developed and emerging countries have been analysed with the same methodology in relation to gender and CO2 emissions. Moreover, this research differentiates between emission-sensitive and insensitive sectors, and it is the only study to carry out a sector-by-sector and a country-by-country analysis. Furthermore, cultural diversity on corporate boards has been scarcely studied so far in relation to CO2 emissions. • Gender diversity on boards of directors is associated to lower CO2 emissions. • Cultural diversity on boards of directors is positively related to CO2 emissions. • Improving gender balances on board of directors is a sustainable strategy. • Gender equality policies on corporate boards favor climate action and life on land. • Legal gender quotas on corporate boards contribute to good health and well-being.
