Table of papers reviewed Abstract This literature review examines the relationship between sustainability reporting andcorporate financial performance by systematically analyzing 30 empirical studies.Most reviewed studies find a positive correlation between sustainability reporting, The review identifies three principal mechanisms through which sustainability reporting 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 – realizestronger financial benefits from robust sustainability disclosures. Significant methodologicallimitations constrain the robustness of existing research, including inconsistent measurement These challenges complicate causal inference and contribute to the mixed empiricalfindings observed across studies. The review concludes that while sustainability reportingshows promise as a value-creation mechanism, particularly when aligned with recognizedstandards such as GRI, future research must address current data inconsistencies and Keywords:sustainability reporting, financial performance, GRI Standards, corporate social 1. Introduction In recent years, thousands of organizations, including most large publicly listed companies,have adopted sustainability reporting practices, often on a voluntary basis [1]. While GRIsupports sustainability reporting primarily as a means of enhancing transparency and The underlying rationale is that transparent and credible sustainability reporting signalsgood governance and forward-looking management, while also providing comparableinformation, which can be rewarded by investors and other stakeholders. Evidence frommultiple studies also shows that organizations with consistent, high-quality sustainability This publication explores the business case for sustainability reporting through thelens of financial performance. If sustainability disclosures can improve access to The literature on this subject presents mixed findings. While most of the studies identifya positive relationship between sustainability reporting and financial outcomes, somesuggest that the effects may be insignificant or even negative. To better understand these The objective of this review is to synthesize current knowledge, highlight patterns anddivergences in the findings, and identify the factors that moderate the relationship between The literature review focused on academic sources published in English. A total of 30articles were included in the analysis and summarized in a thematic table covering thefollowing topics: methodology, findings, limitations, correlations found, and other notes.Four additional systematic literature review papers covering the same research question as The rest of this paper is organized to guide the reader from existing knowledge to newinsights. Section 2 presents the results and discussion of the 30 empirical studies analyzedfor this review, including key findings on various financial outcomes and potential causalpathways through increased access to capital, operational advantages, risk management,and industry-specific effects. Section 3 outlines methodological limitations and data 2. Results and discussion This section summarizes the key conclusions from the 30 studies reviewed. The list of these The majority of studies in this review identified a positive relationship between sustainabilityreporting and financial performance (see Table 1), but this relationship is articulated Business case for sustainability reporting This literature review identifies two primary categories of financial metrics used to evaluate thelink between sustainability reporting and corporate financial performance: accounting-basedprofitability measures (e.g., return on assets (ROA) and return on equity (ROE) and stockmarket-based measures. The latter can be further subdivided into valuation-based indicators,such as ‘Tobin’s Q’, which capture long-term investor expectations and the market’s assessment Profitability measured by return on assets and return on equity ROA and ROE are accounting-based metrics that measure a company’s internal efficiencyand profitability. ROA indicates how effectively a company’s management is using its totalassets to generate profits (net income/total assets); a higher ROA signals efficient assetutilization. ROE measures the return generated on the shareholders’ invested capital (netincome/shareholders’ equity). A higher ROE is attractive to investors because it shows how This relationship is substantiated by empirical evidence across divers
