The Evolution and Integration of ESG Reporting: A Framework for Sustainable Business Accountability

ABSTRACT This study examines how multinational corporations incorporate Environmental, Social, and Governance (ESG) reporting frameworks to foster trust, enhance legitimacy, and move beyond mere symbolic disclosure. A qualitative comparison of Microsoft and Unilever from 2020 to 2023 assesses how both firms integrate leading standards, including GRI, SASB, TCFD, CSRD, and IFRS S1/S2, in response to rising regulatory pressure and stakeholder expectations. Drawing on sustainability reports, assurance statements, financial filings, and third‐party assessments, the findings demonstrate that Microsoft adopts an investor‐oriented approach characterized by data transparency, digital traceability, and climate‐risk governance. Unilever adopts a socially grounded strategy that emphasizes human rights, supply chain ethics, and stakeholder engagement. Despite differences, both companies exhibit gaps where narrative disclosure outpaces verification. The article proposes an integrated ESG reporting model that harmonizes standards, strengthens assurance, and embeds ESG into governance and financial decision‐making to support more accountable and comparable sustainability reporting.
