Theories underlying environmental, social and governance (ESG) disclosure: a systematic review of accounting studies

Environmental, social and governance (ESG) disclosure has gained momentum in corporate reporting. Addressing a research gap on the subject, this paper aims to explore the theories involved in ESG disclosure studies, thereby shedding light on the dominant theoretical approaches and emerging perspectives that inform this type of disclosure.

A systematic review of 142 selected accounting studies published up to June 2023 devoted to ESG – and corporate social responsibility (CSR) – disclosure was conducted. The theories underlying these studies were examined through a descriptive performance analysis complemented by a systematic qualitative text analysis using RStudio and QDA Miner software tools.

The study reveals that five dominant theories stand out among the overall 32 found: stakeholder theory first, followed by legitimacy, institutional, agency and signaling theories. Theories are often combined into an integrated theoretical framework. The findings also show an array of minor constructs – many of them unconventional – that offer fresh perspectives for studying ESG disclosure, such as upper echelons, stakeholder salience, cognitive cost and reputation theories, among others.

This paper provides an original literature contribution by offering a comprehensive overview of the mainstream and niche theoretical perspectives underpinning accounting studies focused on ESG disclosure, with a nuanced scope of discussion on the use of ESG/CSR terms.
