1. Introduction
Reports such as "The Limits to Growth―A Report for The Club of Rome's Project on the Predicament of Mankind" [
1] and "Our Common Future―Report of the World Commission on Environment and Development" (World Commission on Environment and Development [
2], [
3], identified systemic sustainability problems and were essential to support the concept of Sustainable Development (SD) worldwide.
Holistically, humanity can adopt a global development strategy based on the concept of SD―that is, ''development that meets the needs of the present without compromising the ability of future generations to meet their own needs'' [
2] [
3]. In this context, the concept of SD implies a focus on the Planet and People [
4] [
5]. According to Isaksson [
5], ''People and Planet could be defined as the primary stakeholders" (p. 489). Hence, the concept of SD is fully aligned with the economic, environmental, and social dimensions (see [
6], [
7], [
8]). Furthermore, SD is not only an issue for world nations but also for organizations [
9]. Consequently, at the organizational level, the concept of SD is generally approached by several authors as Corporate Sustainability (CS) and Corporate Social Responsibility (CSR) [
10] [
11] [
12]. Strategic CS (or Strategic CSR) requires organization to engage in socially and environmentally responsible activities that are economically sound for their financial performance usually in response to the businesses’ stakeholders’ expectations and demands [
13] [
14].
CSR can generate value for shareholders, customers, workers, partners, and society [
15]. Amongst the CSR-reported benefits are risk reduction, staff recruitment and retention, cost savings, and good stakeholder relationships [
16]. Hence, while supporting the organizations legitimacy, CSR can also foster competitive advantage by facilitating the access to capital and support from different stakeholders [
17].
Figure 1 shows the holistic process of the evolution of the concept of SD from the macro-level (macroscale―planet and its nations) to the micro-level (microscale―organizations and their interested parties), as already advocated by many authors (e.g., [
18], [
19]). The interested parties (i.e., natural, or legal persons who relate to organizations) represent humanity and society at large. Interested parties (i.e., stakeholders) are "any group or individual who can affect or is affected by the achievement of the organization’s objectives" [
20].
In an approach to SD, the term "goals" means "what it seeks to achieve" [
23]. In turn, "results" is generally a synonym for "metrics, information, measures, indicators, outcomes, and outputs [
24]. Thus, effective communication of the organisations' Sustainable Development Goals (SDGs) and Sustainable Development Results (SDRs) to their interested parties is essential for promoting the concept of SD, as well as for promoting the organisations' achievements [
25]. To support these aims, frameworks, guidelines, indices, and standards are fundamental for organisations to achieve their SDGs and communicate the intended SDRs [
26]. The relevance of companies disclosing their contributions to SD is also highlighted by Directive 2014/95/EU of the European Parliament and of the Council of October 22, 2014" and it represents one of the main innovations introduced by the European Commission to encourage large companies to disclose their contribution to SD" [
27].
The level and the content of sustainability information on company reports are increasing worldwide [
28]. From a theoretical perspective, Stakeholder, Resource Based View, and Institutional theories support the communication of the SDG and SDRs [
29] [
30]. The success of an organisation depends on its collaboration with multiple stakeholders [
20], and Stakeholder Theory integrates business and social issues [
31]. Furthermore, the Resource Based View theory [
32] [
33] suggests that an organisation's resources are essential to superior firm performance, competitive advantage, and strategic success. Hence, the adoption of strategies and actions towards SD can develop rare, valuable, inimitable, and non-substitutable resources and capabilities that can help an organisation integrate with stakeholders (a unique resource) and respond to their demands, and ultimately achieve superior performance, as advanced by Stakeholder Theory.
In addition, the Institutional theory posits that organisations, to achieve legitimacy and support, align their social values systems with those expected by society and are pursued by the best organisations to increase the likelihood of survival [
34]. Moreover, academics such as Camilleri [
35] consider that "CSR communications and stakeholder engagement may bring shared value to business and society by engaging with key stakeholders to address societal, environmental, governance and economic deficits" and support managers to improve their organisational stewardship and to reinforce their legitimacy with institutions and other stakeholders in society [
36].
Hummel and Szekely [
37] advance that the ambition to achieve the SDGs must be the responsibility of the governments of all the 193 member states (nations) of the UN and the top management of all organisations and "depends on the joint efforts of all individuals, organisations, and governments" [
38]. However, barriers such as resource limitation, the COVID-19 pandemic [
39], and the war in Ukraine [
40] have negatively impacted the SDGs fulfilment with adverse outcomes for humankind and the planet. Moreover, the SDGs were developed by and for the government, and some organisations might need help understanding them [
41]. Hence, supporting organisations to comprehend, integrate and contribute to the SDGs is critical. Moreover, business leaders must adopt sustainable business models and operate more ethically [
42].
The growth of global supply chains fostered the adoption of voluntary management systems standards (MSS) as regulatory mechanisms to respond to stakeholder concerns [
43]. These MSSs can be audited and certified by independent external certification bodies (CBs) that, by performing a third-party audit, assess whether the applicable MSS complies with the international reference and achieves the intended results [
12]. Several MSSs, namely those published by the International Organization for Standardization (ISO), can support organisations addressing several potential issues inherent to the SD economic, environmental, and social dimensions. Since MSSs certified organisations should comply with international validated requirements and the corresponding certification bodies are subject to the accreditation schemes, the accredited certification is an assurance that all certified organisations, regardless of the country of origin or company size and industry, comply with the same requirements and achieve the intended standards results. Therefore, contributing to the generalisation of the research results to similar certified organisations worldwide.
Furthermore, entities such as the Social Accountability International (SAI), the British Standards Institution (BSI), and the Portuguese Institute for Quality (IPQ, "Instituto Português da Qualidade"), also published MSSs with an SD scope ([
19] [
21] [
44] [
45] [
49]).
ISO MSSs share common concepts, core text, and high-level structure to facilitate the harmonisation and unity of the several MSSs [
46] and academic research posits formal standards are perceived by stakeholders to positively contribute to achieving the SDGs [
47]. Moreover, ISO and GRI promote their alignment with the UN SDGs and CBs work to effectively support that aim [
21].
Table 1 presents four main MSS disciplines of MSSs that contribute to an integral approach to SD at the organisational level and supports achieving their goals and intended results [
48] [
49] [
50] [
51] [
52].
In the last three decades, the implementation and certification of Quality, Environmental, Occupational Health and Safety, and Social Responsibility (QEOH&S&SR) MSs have increased worldwide and specifically in Portugal [
56] [
57] [
58] [
59] and the strategies for adopting multiple MSs certified are well reported in the literature [
60].
The organisations that strategically adopt MSSs in the various disciplines and implement their integration based on the PDCA (Plan–Do–Check–Act) cycle promote SD and communication with the interested parties [
11] [
18]. Consequently, the integration of MSSs (Integrated Management Systems (IMSs) allows the development of ''conceptual models" that show the mechanism for the disclosure of SD goals and results to interested parties (e.g., [
11] [
18] [
45] [
60] [
61].
Table 2 shows the relationship between the three dimensions of the SD, the potential issues associated with the SD, and the main MSSs currently adopted by Portuguese organisations.
Corporate sustainability (CS) reports have become the instrument of companies to communicate sustainability issues with their stakeholders and move forward to the balance of the Triple Bottom Line [
62]. However, SDGs and SDRs reporting still have many issues that deserve research [
27] [
63] [
64]. Presently, the institutional website of organisations with certified MSSs is considered an effective communication channel for disclosing institutional reports and information on SD [
11] [
18]. Recent academic research addresses the existing corporate reporting concerning SDGs [
9] [
65]. Moreover, [
78] [
19] propose an evaluation framework to identify the amount of disclosure topics from CSR/sustainability reports regarding SDGs. Furthermore, Izzo et al. [
66] investigated the information disclosure in European companies integrating reporting (IR) guidance used to cover issues concerning SDGs.
Holistically, the object of study of this investigation aims to propose a framework to integrate Sustainability within Management Systems Standards and subsequently implement and disclose Sustainable Development goals and results and answer the following three ‘Research Questions’ (RQ):
RQ1: What are the main SDGs disclosed in institutional reports by Portuguese organisations with multiple certified MSs (QEOH&S&SR)?
RQ2: What are the main SDRs disclosed in institutional reports by Portuguese organisations with multiple certified MSs (QEOH&S&SR)?
RQ3: How the disclosure of SDGs and SDRs in institutional reports is correlated?
This paper contributes to the literature on SDGs in several ways. First, most of the available academic research has provided theoretical reflections on the SDGs [
67]. Further research should address how sustainability can be better understood and managed at an organisational and local level [
68]. By integrating GRI and MSs and fostering SDGs and SDRs communication, this study can support organisations to comprehend, integrate and contribute to the SDGs. Hence, the contributions of this research are twofold. First, it supports the integration of the SDGs within organisations, and second, it stimulates the demonstration of their impacts on the SDGs (the SDRs).
The remaining of the article is organised into the following sections:
Section 2 addresses the Literature review;
Section 3 presents the Materials and Methods;
Section 4 exposes the Results;
Section 5 shows the Discussion; and Section 6 reveals and highlights the Conclusions of the study and presents the mains limitations, restrictions, and recommendations for further research. By integrating GRI and MSs and fostering SDGs and SDRs communication, this study can support organisations to comprehend, integrate and contribute to the SDGs.
5. Discussion
This research results show that the accounts and sustainability reports are the most frequently disclosed among the several institutional reports published and disclosed annually on the institutional website by Portuguese organizations with multiple certified MSs. Thus, our results align with other previously published studies (e.g., [
11] [
72] [
106]).
Consequently, the four main SDGs (i.e., UN SDGs items) disclosed in institutional reports by certified Portuguese organizations (QEOH&S&SR) are the following (in descending order): "life on land" (SDG 15); "industry, innovation, and infrastructure" (SDG 09); "responsible consumption and production" (SDG 12); and "partnerships for the goals" (SDG 17), these last three in ex aequo in terms of ranking. Therefore, in this research, SDG 15 is highlighted as the goal most disclosed of all the SDGs—the main SDG disclosed in institutional reports. However, recent research shows that SDG 15 usually does not occupy a rank among the top five of the SDGs most disclosed in institutional reports (e.g., [
37] [
65] [
66] [
86] [
106] [
109]). Additionally, some recent studies identify SDG 15 among the least attention and priority SDGs for organizations (e.g., [
28] [
37] [
66]). Consequently, in our case, we believe that the result obtained for SDG 15 may be related to the characteristics of the research sample—that is, Portuguese organizations with multiple certified MSs (QEOH&S&SR) that are aligned with the principles of the SD.
Overall, the results obtained for the items SDG 09, SDG 12, and SDG 17 are in line with other research (e.g., Fonseca & Carvalho [
65])—that is, the SDG 09, SDG 12, and SDG 17 are among the top five SDGs disclosed in institutional reports by certified Portuguese organizations. However, other recent studies show that only SDG 9 and SDG 12 are among the top five SDGs disclosed in institutional reports (e.g., Hummel & Szekely [
37]; Izzo et al. [
66]; Manes-Rossi & Nicolò [
29]). On the other hand, however, we found in other research that only SDG 12 is among the three, four or five SDGs most disclosed in institutional reports (e.g., Gunawan et al. [
110]; Heras-Saizarbitoria et al. [
115]; Ionașcu et al. [
38], Ivic et al. [
86]; PwC [
28]; Silva [
59]).
Additionally, the four main SDRs (i.e., GRI items) disclosed in institutional reports by certified Portuguese organizations (QEOH&S&SR) are the following (in descending order): 'employment' (GRI 401); 'economic performance' (GRI 201); 'anti-corruption' (GRI 205); and 'occupational health and safety' (GRI 403). In our case, the GRI 401 is the most disclosed SDR in institutional reports. In turn, Bastas and Liyanage [
116] argue that the GRI 201; GRI 205, and GRI 403 are all sustainability items (i.e., SDRs) priorities as per the voice of the stakeholder's analysis.
Overall, the results obtained for the items GRI 201, GRI 401, and GRI 403 are in line with other research (e.g., Carvalho [
106])—that is, the GRI 201, GRI 401, and GRI 403 are among the four main SDRs disclosed in institutional reports by certified Portuguese organisations. In addition, other research shows that the theme of GRI 201, GRI 401, and GRI 403 are in the top ten SDRs disclosed in institutional reports (e.g., Lambrechts et al. [
117]).
According to Pacheco et al. [
81], items GRI 201 and GRI 401 are among the most disclosed in institutional reports (a specific case of the universities). On the other hand, Yang et al. (2020) shows that item GRI 201 is the sub-topic (i.e., GRI item) most disclosed in the economic dimension for the specific case in the airline industry. Conversely, Saber and Weber [
73] argue that the items GRI 401 and GRI 403 are among the most disclosed in institutional reports (a specific case of grocery retailing).
Holistically, our results show that more than half of the SDRs (i.e., GRI items) disclosed in institutional reports belong to the social dimension (GRI 400). On the other hand, the SDRs disclosed referring to the economic (GRI 200), and environmental (GRI 300) dimensions are similar. Therefore, this study's results align with other previously published research (e.g., Kolsi et al. [
118]).
Recently, in the literature, the integrated approach to SDGs (based on UN SDGs items) and SDRs (based on GRI standards items) disclosed in the institutional reports of the organizations is showing the first results (e.g., [
63] [
78] [
84]). However, Diaz-Sarachaga [
63] argue that "the correlation between the SDGs and CS reporting systems has barely been studied" (p. 1299), for example, the correlation between the SDGs and the GRI standards. In this context, our research's results demonstrated statistically that the disclosure of SDGs (i.e., UN SDGs items) and SDRs (i.e., GRI items) in institutional reports present a strong positive correlation.
5. Conclusions
According to the literature, the implementation and certification by the organizations of multiple MSs (QEOH&S&SR) allow demonstrating to stakeholders a responsible commitment in favor of the SD. In Portugal, the number of organizations with multiple certified MSs (QEOH&S&SR) is a reality that has grown in recent years. Usually, the Portuguese organizations with multiple certified MSs (QEOH&S&SR) publish annually various institutional reports on the institutional website (on the Internet) to disclose contents on SD to stakeholders. In turn, the accounts and sustainability reports are the institutional reports most frequently used to disclose the SDGs (i.e., UN SDGs items) and the SDRs (i.e., GRI items) to interested parties. Therefore, holistically, the object of study of this investigation was achieved with the proposal of a framework to integrate Sustainability within Management Systems Standards and subsequently implement and disclose Sustainable Development goals and results and the answer to the three "Research Questions" (RQ) initially proposed.
In answer to RQ1: What are the main SDGs disclosed in institutional reports by Portuguese organizations with multiple certified MSs (QEOH&S&SR)? We found that the four main SDGs disclosed in institutional reports by certified Portuguese organizations (QEOH&S&SR) are the following (in descending order): "life on land" (SDG 15); "industry, innovation, and infrastructure" (SDG 09); "responsible consumption and production" (SDG 12); and "partnerships for the goals" (SDG 17), these last three in ex aequo in terms of ranking. Thus, SDG 15 is the goal most disclosed of all the SDGs in institutional reports. Overall, SDG 15 ('life on land') focuses on People and Planet.
In response to RQ2: What are the main SDRs disclosed in institutional reports by Portuguese organizations with multiple certified MSs (QEOH&S&SR)? We found that the four main SDRs disclosed in institutional reports by certified Portuguese organizations (QEOH&S&SR) are the following (in descending order): 'employment' (GRI 401); 'economic performance' (GRI 201); 'anti-corruption' (GRI 205); and 'occupational health and safety' (GRI 403). Consequently, the GRI 401 is the result most disclosed of all the SDRs—the main SDR disclosed in institutional reports. Overall, the GRI 401 ("'employment") focuses on People.
In reply to RQ3: How the disclosure of SDGs and SDRs in institutional reports is correlated? We found that the SDGs and the SDRs disclosed in institutional reports by certified Portuguese organizations (QEOH&S&SR) are statistically significantly correlated. Accordingly, our research statistically demonstrated that the disclosure of SDGs and SDRs in institutional reports has a strong positive correlation. Moreover, there is an emphasis on the environmental dimension within SDGs disclosure and on the social dimension for SDRs disclosure, with the economic dimension present in both SDGs and SDRs. Overall, the contributions of this research are twofold. First, it supports the integration of the SDGs within organizations and proposes a model for SD implementation through MSSs. Second, it stimulates the demonstration of organizations impacts on the SDGs (the SDRs). Hence, these findings contribute to the state of the art of knowledge in this study area, as the research on the relationship between the disclosure of SDGs and SDRs is still at an early stage. Moreover, it can support organizations to comprehend, integrate and contribute to the SDGs, by adopting MSSs.
The research sample size and the limited number of institutional reports analyzed are limitations and restrictions that affected the present investigation. However, since MSSs certified organizations should comply with international validated requirements and the corresponding certification bodies are subject to the accreditation schemes, ensuring confidence and the compliance with the applicable MSs requirements, the study results can be generalized to similar certified organizations worldwide.
Finally, we propose as possible future developments of this investigation the realization of similar studies with post COVID 19 data and with certified organizations from other countries to assess different countries’ patterns and the possible generalization of this research results.
A Business Model supports organizations in creating, delivering, and capturing value, and Business Excellence Models have been proposed to integrate the SDGs while delivering outstanding results and promoting transformation [
119]. Nevertheless, frameworks are needed to support the many certified MSSs organizations worldwide to achieve those aims. By integrating Sustainability within Management Systems Standards and subsequently implementing and disclosing Sustainable Development goals and results, the proposed framework can align and integrate Sustainability with the organizations' strategy, processes and key performance indicators and results. This contribution raises the awareness of SD goals and results publications within organizations with certified Management Systems Standards. It answers the calls for more emphasis on the SDGs and the support of MSSs for that aim [
120] [
121] [
122]. It can support academics and decision-makers (focusing on business leaders and organization managers) to comprehend, integrate and contribute to the SDGs. Moreover, it can motivate other researchers to replicate this study in different contexts.
