Do board attributes influence environmental sustainability disclosure in manufacturing firms? Evidence from sub‐Saharan Africa

The study builds and extends on the literature on the environment, corporate governance, and sustainability by examining how board attributes impact environmental sustainability disclosure (ESD) and, if so, whether each of the two strands of board attributes, namely, board diversity and structural attributes, influence ESD for manufacturing firms in the sub‐Saharan Africa (SSA) region. Based on insights drawn from the human capital theory and board composition, the study developed a model that connects board attributes with ESD. Using a sample of 200 manufacturing firms from 2010 to 2022, the study found an inverse link between gender diversity and ESD, whereas a positive connection was seen between foreign nationals and ESD. Regarding structural attributes, an inverse link was found between board size and ESD, while a positive connection exists between the separation of the board chair from the chief executive officer and ESD. In summary, the findings urge policymakers in the SSA region to strengthen policies on board diversity and structural attributes to promote ESD. Moreover, the findings advise the board of directors to ensure effective and transparent disclosure of environmental‐related issues to stakeholders to guarantee sustainable reporting practices.
