Abstract :This study will evaluate the sustainability performance of five leading insurance companies in Türkiye for 2021. Unlike other studies, this research employed sub-criteria and the three basic dimensions of sustainability. The criteria weights were determined using the Spherical Fuzzy AHP method, a novel approach in the literature. Thus, the importance of the basic dimensions of sustainability was determined. It was seen that environmental dimensions had the most impact, followed by social and economic dimensions, respectively. TOPSIS, CODAS and PIV methods were used to rank the companies. The results obtained with the three methods were combined with the Borda Counting method to get the final ranking. According to the results, the company with the highest sustainability performance was Euroko Insurance Company.
