Effect of board characteristics on the sustainability performance of selected JSE listed companies in South Africa

Abstract

This study examines the effect of board characteristics on environmental and social sustainability performance. Companies‟ sustainability performance is affected by many factors such as board composition of companies, lack of knowledge, policies and resources of companies, competition from other companies and market trends. The King IV Code of Corporate Governance recommends that the governing body should comprise a balance of diversity being race and gender and independence. Moreover, the Code states that the board of directors of companies should have a balance of both independent members and non-independent members who should act in the best interest of the companies. The study used a quantitative approach, and secondary data from Johannesburg Stock Exchange (JSE), Socially Responsible Index (SRI) listed banking and retail companies for 11 years from 2007-2017. The study tests the relationship between board characteristics (the number of females on board of directors); firm size (market capitalisation); board independence; and environmental (energy usage) and social (skills development expenditure) sustainability of JSE SRI listed firms. Results show that there is a negative and insignificant relationship between females on board and energy usage. A positive and a significant relationship between energy usage and board independence a positive and an insignificant relationship between firm size (market capitalisation) and energy usage. There is also a positive but an insignificant relationship between skills development expenditure and female board members and a positive and significant relationship between skills development expenditure and board independence and a positive and an insignificant relationship between skills development and firm size (market capitalisation). The study suggests that for companies improve their sustainable business practices; they should consider increasing the number of v | P a ge females on their board since they have a positive influence on sustainability performance.
