Board Diversity and Sustainability Reporting: Evidence from Industrial Goods Firms

The sustainable development goals (SDGs) adopted by all the United Nations member countries were to reduce the social and ecological outcome of businesses and governments across the globe, among others. Businesses can key into this agenda by disclosing their economic, environmental and social impact in their financial reports. However, in Nigeria, the extent of sustainability reporting amongst firms is still low and not a listing requirement. Against this backdrop, this study investigated the influence of a diverse board on the extent of sustainability reporting in listed industrial goods firms on the Nigerian Stock Exchange from the period 2014-2018. We developed a sustainability disclosure index using the Global Reporting Initiative (GRI) guidelines to score the information content of annual reports relating to sustainability performance. Nationality, age and educational level were used to proxy diversity in the boardroom. The study also used descriptive and inferential statistics to summarize the data and to draw an inference on the population studied. Our study failed to validate the theoretical framework - Stakeholder-Dependency Theory used in the study, as results from the panel least squares regression revealed that age diversity in the boardroom negatively and significantly affects the extent of sustainability reporting. Furthermore, we found no evidence on the nexus between nationality diversity and sustainability reporting; and education level diversity and sustainability reporting. The study concluded that diversity in boardroom influences the extent of sustainability reporting in Nigeria. This study recommends that firms should increase the representation of foreign directors in the boardroom because they add value and a wealth of experience to the board.
