The contextual background of this research is focused on digital CSR disclosure, one of the most debated concepts in the business literature (Newman et al., 2020) because of its ability to create enterprise value (Dhaliwal et al., 2014). Thus, it could be considered as an important tool for the sustainability of bottled water companies.
Moreover, corporate social responsibility reporting has been increasing over the last decade and has become a matter of strategic importance to business enterprises (KPMG, 2013; Scholtens & Dam, 2007; Stolowy & Paugam, 2018) as it draws significant attention from several stakeholders (Branco & Rodrigues, 2008). This trend in modern companies will maximise the company’s value to shareholders, satisfy the expectations of stakeholders and lead the company to behave in a socially responsible way and to adopt the concept of managing resources for the welfare of present and upcoming generations (Lipunga, 2014).
The authors have observed an increase in the availability of CSR reports, but the level and content of SRD are influenced by several factors. Thus, problems arise with the quality and quantity of the information disclosed. In addition to company size, number of employees, ownership, profitability and the nature of the industry, the company’s age and the presence or absence of social responsibility boards (Akin & Yilmaz, 2016) determine the level of digital disclosure. Thus, the following hypotheses are proposed:
H1: CSRD is positively correlated with firm age.
H2: CSRD is positively correlated with number of employees.
Several investigations of European Union (EU) countries by different authors have concluded that CSR reports differ from country to country (Habek, 2014; Mio & Venturelli, 2013; Sierra et al., 2013; Skouloudis et al., 2014) since legislation varies widely in several states (Habek & Wolniak, 2013a; 2013b).
For this reason, it is fundamental to use an internationally recognised tool for the assessment of information, such as the information from the GRI standard used in this research to classify level of disclosure. The GRI reporting framework is widely acknowledged as a leader in the international standardisation of sustainability reporting (Bebbington et al., 2012; Gray, 2010; Mahoney et al., 2013). It is also considered the primary example of sustainability reporting and has multiple applications in firms in several sectors of activity (GRI, 2021a; Joseph, 2010; Lipunga, 2014).
Previous research suggests that the level of CSR policies in large companies is higher than that of small companies (Font et al., 2012). Branco and Rodrigues (2006) concluded that banks with higher visibility show more concern for corporate social disclosure to improve their images than do banks with lower visibility. Similarly, Cuganesana et al. (2010) studied the Australian food and beverage industry and found that firms from industry subsectors with innovative CSR profiles comprise a better disclosure. Thus, the following hypotheses are proposed:
H3: CSRD is positively correlated with firm size.
H4: CSRD is positively correlated with turnover.
Previous research also reports that companies with larger ownership have the highest disclosure levels and respond proactively to stakeholder concerns (e.g., Barnea & Rubin, 2010; Burritt et al., 2016; Li & Zhang, 2010; Paek et al., 2013; Scholtensm & Kang, 2013;). In contrast, Shnayde et al. (2016) showed that motivations for CSR disclosure in the packaged food industry depend on intrinsic factors and can be explained by external pressures, regulation, normative obligations and social pressure (Shnayder el al., 2016).
Other studies have focused on the relation between CSRD and accounting or finance variables, and most of them have determined that CSR disclosure improves the financial performance of companies (Kartasasmita, 2020; Nair et al., 2019).
Thus, the following hypotheses are proposed:
H5: CSRD is positively correlated with return on equity (ROE).
H6: CSRD is positively correlated with return on assets (ROA).
However, the new trends for the companies that disseminate online information have changed the line of research in this field. Previous studies focused only on the annual report, while current studies are also based on a company’s online reporting (e.g., Campbell & Beck, 2004; Capriotti & Moreno, 2007; Chaudhry et al., 2007; Choi J., 1998; Esrock & Leichty, 1998, 2000; Maignan & Ralston, 2002).
For this reason, company websites play a significant role in CSRD through easy access to CSR agendas and circulation of updated data about social and environmental management performance to a varied group of internal and external stakeholders that is accessible twenty-four hours a day, seven days a week (Adams & Frost, 2006; Cooper, 2003; Darus, 2009; Frost et al., 2005; Gautam & Shagun, 2018; Hinson, 2011).
Online channels are an important tool for bottled water companies since researchers have suggested that company websites could provide organisations with numerous opportunities to present and explain to their stakeholders their CSR identity, product sales and management subjects (Campbell et al., 2011, Rolland & Bazzoni, 2009).
It is unquestionable that communication through company websites is crucial in today´s world of globalisation and liberalisation (Dehkordi et al., 2012; Lipunga, 2014). It is an extremely powerful tool to influence the success of companies by increasing their visibility and disclosing information in a cost-efficient way to a target audience that is more aware of CSR and to potential financial investors that tend to capitalise companies with better environmental and social performance (O‘Rourke, 2004; Penczar, 2003). It is clear that a company’s website image has a considerable influence on stakeholder behaviour (Chen & Lee, 2005).
Essentially, research on digital information is of particular interest since the web offers several benefits for communication purposes which can increase the information that is communicated to customers and other stakeholders (Amran, 2012). The Internet and its channels have opened a track for personalisation of messages and real interaction with both existing and potential customers which could lead to a better fit between customer expectations and firm growth (Dutot et al., 2016). However, the content of websites is not standardised, and companies voluntarily determine the information that they desire to disclose (Amran, 2012). This provides an opportunity from the academic point of view to research the CSR online disclosure phenomenon, from the context of bottled water companies. For that reason, the bottled water industry must develop high quality websites which provide a better online experience to attract all stakeholders, explain the identity of the brand and simplify access to information in a perceivable, operable, comprehensible, and robust way (Chen & Lee, 2005).
In the wider society, digital SR disclosure is on the rise, and Portugal is no exception (Barros, 2008). A few years ago, Branco and Rodrigues (2006) found that most Portuguese companies did not disclose social responsibility information on their websites, but small- to medium-sized business enterprises are now considered active with CSR agendas (Branco, 2015; Coupland, 2006). Similarly to other EU countries such as Italy and Spain, Portugal has adopted CSR policies that depend most of the time on the promotion of government initiatives (Albareda et al, 2007; Knudsen et al., 2015; Maon et al., 2017), and only a few Portuguese companies are included in international sustainability indexes (e.g., Dow Jones Sustainability Index [DJSI] or the FTSE4Good Index), typically with a low classification in terms of CSR reporting and the inclusion of voluntary CSR standards in their businesses (Branco, 2015; Branco & Delgado, 2011; Moon et al., 2012).
Therefore, it is important to know the current Portuguese reality. The data presented in this study are used to evaluate the level of CSR reporting in the Portuguese field in the context of online disclosure by bottled water companies and to identify the aspects that influence this disclosure. This is a sector of extreme economic importance for the country, and it is considered to be a global industry (Carlucci et al., 2016), but due to recent pressures from the market and stakeholders, the fulfilment of environmental laws needs to demonstrate commitment to the environment through the preservation of a pure and natural resource bottled in 100% recyclable packaging with the incorporation of recyclable materials, factors that are included within CSR agendas nowadays.
