“…In addition, the reliability of sustainability disclosure has been widely criticized in the literature. Among other things, many studies have highlighted the lack of transparency of sustainability disclosure, the tendency to hide information that can damage companies' image, trends toward greenwashing, and the use of sustainability information as a public relations tool (e.g., Cho et al, 2015; Haller, Van Staden, & Landis, 2018; Kim & Lyon, 2014; Laufer, 2003; Marquis, Toffel, & Zhou, 2016; Ramus & Montiel, 2005). Although the assurance of sustainability reports by external auditors is assumed to improve the reliability of information, the actual effectiveness of such processes is controversial (Boiral, Heras‐Saizarbitoria, & Brotherton, 2019; O'Dwyer & Owen, 2005; Seguí‐Mas, Bollas‐Araya, & Polo‐Garrido, 2018; Smith, Haniffa, & Fairbrass, 2011).…”
