Forests are crucial in sustaining life on Earth and are at the core of global sustainability efforts, to which Forest Stewardship Council (FSC) certification makes a significant contribution. Changes in motivations, benefits, and challenges associated with FSC certification among Croatian companies, particularly in light of recent market fluctuations and global sustainability trends, have been examined in this study. The research was conducted in 2015 and 2023 using a survey method among FSC chain of custody (CoC) certificate holders in Croatia. A statistically significant decline in the proportion of companies citing customer demands and company image as the main reasons for FSC certification was observed, while environmental awareness became a more prominent motivation. Additionally, although key benefits such as retaining existing customers and attracting new ones remain important, a significant decline in the proportion of companies reporting increased profits as a benefit was noted. Challenges related to extensive documentation and frequent changes in standards also significantly increased. This study suggests that FSC certification remains crucial for maintaining competitiveness in the Croatian wood industry, especially as environmental concerns gain importance. Given that FSC standards help enforce European sustainability regulations, FSC certification is important for ensuring long-term resilience and success in an unstable market environment.
