Most reviewed studies find a positive correlation between sustainability reporting, particularly reporting aligned with the GRI Standards, and financial outcomes, while the results vary considerably across contexts, methodologies, and measurement approaches. The review identifies three principal mechanisms through which sustainability reporting may enhance financial performance: 1. Improved access to capital;2. Operational efficiency gains; 3. Enhanced risk management capabilities. Organizations in high-risk industries – such as energy, mining, and manufacturing – realize stronger financial benefits from robust sustainability disclosures. Significant methodological limitations constrain the robustness of existing research, including inconsistent measurement of sustainability reporting quality, limited temporal coverage, incomplete firm-year observations, and the absence of standardized assessment frameworks.These challenges complicate causal inference and contribute to the mixed empirical findings observed across studies. The review concludes that while sustain...
