Sustainable development is a priority to the United Nations. Moreover, investment managers consider envi- ronmental, social and governance score as an important variable in portfolios selection. The fifth goal in the 2030 Agenda is gender equality. Besides, European countries have established gender quotas on corporate boards to reduce the gender gap. Empirical studies about the influence of women directors on the company's corporate social responsibility (CSR) presented mixed results, especially in developing countries. This article compares the influence of gender diversity on corporate boards on CSR performance in developed and emerging European markets. We apply a panel data methodology with fixed effects to examine the compa- nies listed in the MSCI Europe and MSCI EM Europe indices from 2010 to 2019. The results show that gender diversity on the board of directors influences CSR performance positively, and this influence is greater in developed countries. Consequently, legislation should promote gender policies.
