Therefore, this thesis examines the effect of board characteristics, which include board size, board independence, CEO-chairperson duality, female board membership and director tenure, on sustainability performance. The thesis is a quantitative study, which covers altogether 472 listed companies from the Nordic countries – that is, Denmark, Finland, Iceland, Norway and Sweden, for a three- year time period from 2020 to 2022. Thus, the final sample consists of 1 416 firm- year observations across 11 industries, and all the data is collected from Refinitiv. The empirical findings show that board independence and female board membership positively affect firm sustainability performance. Consequently, the effect of board size, CEO-chairperson duality and director tenure on such performance cannot be confirmed at a statistically significant level.
