This paper aims to explore the impact of gender diversity on firms’ sustainability responsiveness in ensuring collective drive toward achieving sustainable development goals (agenda) for Nigeria. This study explored female engagement from three major platforms, namely women as directors, management team leaders, and female workforce. The data used to conduct this study were derived from the annual reports of the sampled banks spanning through the period of 2013–2016. However, while data for this study were analyzed using EViews statistical tool, the sustainability reporting data were ascertained using the content analysis method. The outcome of this study depicts that female directors, female workforce, and women in the management team all had an adverse and positive association with sustainability reporting. However, this association was all insignificant. This further buttresses that gender diversity was not the major driving force behind the sustainability reporting of the sampled banks in Nigeria. This is because the sector is highly regulated. Hence, the study recommends that notwithstanding the outcome, in attaining the sustainable development goals (SDGs), there is a need to have more female representation on the strategic position of authority.
