Abstract This study aims to analyze the compliance levels of companies operating in the Transportation and Logistics sector of the Istanbul Stock Exchange (BIST) with the Turkish Sustainable Reporting Standards (TSRS) for the year 2024, within a multidimensional and comparative framework. The publicly available annual reports of 10 out of 12 companies in the sector that were determined to have published sustainability compliance reports were examined using content analysis. TSRS compliance was structured under four main dimensions: Governance, Environmental, Social, and Stakeholder Engagement; each criterion was scored as 0 (no explanation), 1 (partial compliance), and 2 (full compliance). Criteria not directly related to the field of activity were excluded from the analysis, and a composite TSRSTotal index was created using measurement and dimension indices. Descriptive statistics, reliability analyses, correlation tests, Friedman tests, and hierarchical clustering analysis results obtained using SPSS software showed that the overall compliance level in the sector is moderate, with the environmental dimension exhibiting higher performance. Strong positive relationships between the dimensions indicate that sustainability practices are addressed holistically, while clustering analysis reveals different levels of sustainability maturity among firms. The study contributes to the quantitative and comparable measurement of TSRS compliance at the sectoral level.
