Based on a sample of 4,089 multinational companies over the period 2015-2018, this study analyses the role that women leaders play in relation to the implementation of sustainability strategies to achieve the Sustainable Development Goals (SDGs), and whether this role depends on the proportion of female presence in management teams. The results show that the commitment to the 2030 Agenda is higher in companies with a woman as the Chief Executive Officer (CEO) and/or chairperson of the board of directors, as well as greater gender diversity in both, management teams and the monitoring body. However, the incongruity in the phenomenon of female leadership stereotypes hinders the existence of a complementary relationship that reinforces it. We showed that, consistent with the social role theory, prejudices act as barriers to achieve synergic effects among women in different management positions.
