Greenhouse gas assurance and carbon emission performance in light of the auditor’s reputation and the country’s development level

Abstract

Purpose

The objective of this study is to determine the impact of GHG assurance on firms’ carbon emissions performance (CEP) regarding curbing carbon emissions and the effect on such by the GHG assurance provider’s affiliation and reputation. It also explores whether the affiliation and reputation of GHG assurance providers imply the relationship between GHG assurance and the firm’s CEP. Further, this study examines the moderating effect of the country’s development level on the relationship.

Design/methodology/approach

Based on a sample of international firms from 56 countries spanning the period from 2012 to 2020, this study utilizes the ordinary least squares (OLS) regression. We also run the OLS regression at times t+1 and t+2 to verify the baseline results. To address the endogeneity concerns arising from self-selection bias and the causality effect, this study applies the generalized method of moment (GMM) and the Heckman test.

Findings

This study finds that GHG assurance leads to better CEP by firms. We also find that engaging with accounting assurance providers leads firms to a better CEP than non-accounting assurance providers. Our results show that Big Four auditors can help firms decrease carbon emissions. We also find that the positive effect of GHG assurance is prevalent in firms operating in developed countries.

Research limitations/implications

Our study only considers the influence of the assuror’s reputation and affiliation on CEP without examining other factors that may influence the quality of assurance services provided.

Practical implications

Our study provides a practical implication related to the influence of a GHG assurance provider’s affiliation and reputation globally by providing evidence that accounting and Big Four assurance providers do play a significant role in a firm’s carbon emission performance. This study offers great insights into the GHG assurance impact on CEP with the interplay between the assuror’s affiliation and reputation and the country’s development.

Originality/value

This paper enriches the limit evidence on GHG assurance and CEP by providing novel evidence on the relationship between GHG assurance and a firm’s CEP. Moreover, this study provides insights into the implication of a country’s development level on the role of GHG assurance in CEP.
