Does the level of assurance statement on environmental disclosure affect investor assessment?


Purpose
The purpose of this study is to examine whether different levels of assurance statements of environmental disclosures affect investment choices in the French context where environmental assurance was voluntary until 2012 and became regulated and mandatory since then.


Design/methodology/approach
The authors conducted an experiment during the voluntary context – which represents the vast majority of countries – on a sample of 108 financial analysts.


Findings
Environmental disclosure has a positive impact on investment recommendations. More surprisingly, financial analysts are less likely to give recommendations in favor of a company that displays environmental disclosure with low-level assurance than for a company with no assurance statement at all.


Research limitations/implications
When assurance is voluntary and there are at least two levels, this study results suggest that firms should avoid selecting the lowest level of assurance because it negatively affects investor decisions. From this perspective, firms should devote sufficient effort and resources to obtain at least Level 2 environmental disclosure assurance.


Practical implications
Given the recommendations made by financial analysts, the authors could expect that firms may prefer to engage in a higher level of assurance or to provide no assurance rather than minimize their financial efforts and resources to select a lower level of voluntary assurance regarding environmental disclosure.


Social implications
This study has implications for the voluntary assurance practices of environmental disclosure and can provide support to regulators to promote higher standards in environmental assurance. It documents the relevance to increase the level of requested assurance for environmental disclosure.


Originality/value
To the best of the authors’ knowledge, very few studies have examined the additional effect of assurance on environmental disclosure in investors’ decisions. The experiment is conducted with financial analysts in the context of voluntary assurance.
