Sustainability Accounting in the 21st Century Economy

Abstract

This study explores literature survey approach with content search analysis on existing reports, research papers and publications bordering on Sustainability Accounting and the theoretical foundations and applications of Sustainability Accounting in modern economic systems. Grounded in stakeholder theory, legitimacy theory, institutional theory and normative theory, the study underscores how Sustainability Accounting expands the scope of Traditional Accounting to include Environmental, Social, Governance and Economic (ESG-E) metrics. Reporting frameworks such as the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), and the European Union’s Corporate Sustainability Reporting Directive (CSRD) illustrate the institutionalization of sustainability practices and reflect the growing demand for transparency and accountability. The study revealed that Sustainability Accounting is essential for promoting responsible business conduct and sustainable development and that for businesses to be relevant with greater market share, the non-financial reporting aspect (ESG report) should be taken seriously as it enhances the credibility, reliability and acceptability of the financial reporting aspect (Economic report) in the 21st century economy. As economies become more interdependent and sustainability risks intensify, the integration of nonfinancial reporting into mainstream accounting practices is not just beneficial, it is imperative. Thus, the study concludes that Sustainability Accounting advances accounting thought by recognizing the interconnectedness of environmental, social, governance and economic performance.
