Abstract

Purpose

The purpose of this paper is to investigate whether four corporate governance mechanisms (board size, non-executive directors, ownership concentration and directors’ share ownership) influence the extent of greenhouse gas (GHG) disclosure.

Design/methodology/approach

The study uses a mixed-methods approach based on a sample of 62 FTSE 1,000 firms. Firstly, the authors surveyed the senior management of 62 UK-listed firms in the FTSE 1,000 index to determine whether the corporate governance mechanisms influence their GHG disclosure decisions. Secondly, the authors used ordinary least squares (OLS) regression to model the relationship between the corporate governance mechanisms and GHG disclosure scores of the 62 firms.

Findings

The survey and OLS regression results both suggest that corporate governance mechanisms (board size and NEDs) do not influence GHG disclosures. However, the results of the two approaches differ, in that the survey results suggest that corporate governance mechanisms (ownership concentration and directors’ share ownership) do not influence the extent of GHG disclosure, while the opposite is true with the OLS regression results.

Research limitations/implications

The sample size of 62 firms is small which could affect the generalisability of the study. The mixed results mean that more mixed-methods approach is needed to improve the understanding of the role of corporate governance in GHG disclosures.

Originality/value

The use of mixed-methods to examine whether corporate governance mechanisms determine the extent of GHG voluntary disclosure provides additional insights not provided in prior studies.
