3. Research Framework
The concept of sustainable development is based on the premise that there is a balance between the four essential dimensions, which in fact represent the pillars of sustainable development, and can also be referred to as the four “Ds” of sustainable development [
41], namely human sustainability, social sustainability, economic sustainability and environmental sustainability.
Human sustainability implies the maintenance and continuous development of human capital [
42,
43] within central and local public administration, representing a complex process, characterized by constant investment in education, the development of training and continuous specialization programmes, allowing the transfer of skills with practical applicability in the field of sustainable development.
The recent economic crisis generated by pandemics, the war in Ukraine, ominous climate changes, rapid technological advancements and the minacious scarcity of environmental resources are current global challenges that are compelling authorities and private entities alike to consider the effectiveness of implementing sustainable policies. Such endeavours have focused on the identification of a ”green” mix of skills and knowledge appropriate for raising awareness and proactively implementing sustainable development policies to stimulate research and challenging practice.
In this context, in order to successfully implement public policies with an impact on the environment, and to implicitly increase awareness and implementation of the principle of Do Not Significant Harm (DNSH) [
44,
45], particular attention should be paid to approaches involving the development of new professions/specializations that primarily target the field of sustainable development and that can directly impact the work carried out by human resources [
46,
47] within public administration.
Identifying and prioritising a set of professional skills that can be associated with sustainable development processes, and disseminating and transferring them to those responsible for the field, is a first step towards developing a new type of economic-administrative behaviour in which the linear economic model (take-make-consume-dispose) is replaced by a circular economic model based on the 4Rs reduce-reuse-recycle-recover principle [
48,
49].
The article thus aims to identify and analyse what the civil servant respondents consider to be the level of professional training, as well as the professional skills (professional profile), required/needed to be possessed by human resources working or wishing to work in the field of sustainable development. The answers obtained also provide information on the perception of the usefulness of the existence of a distinct profession, that of the sustainable development expert, of the respondents who participated in this study.
The successful implementation of sustainable development policies depends on having a high level of green skills among employees [
50,
51,
52], skills that are in line with the level of responsibility and the job description of the employee within the organisation. The identification, implementation, nurturing and assessment of the efficiency or usefulness of such skills are key concerns for governance in public or private sectors. The investigation of the perceptions of different practitioners on sustainable expertise yields valuable insights with major theoretical and practical implications, as the following sections of this paper highlight.
5. Findings and Discussion
During an early stage of the study, we tested the reliability and consistency of the Likert scale attributed to each of the qualitative predictors, Specialization, Knowledge, Attributions and Competence, using the Cronbach’s alpha (CA) consistency test. According to
Table 1, the calculated values for the Cronbach’s alpha were greater than 0.8, thus indicating the very good significance of the test. The number of items shown in
Table 1 for each scale variable represented the descriptive categories attributable to such variables. Each descriptive category (N of items) is presented in
Figure 2, under the corresponding variable.
During the next steps of the study, several tests were performed on the database. The analysis sought to identify a combination of characteristics of the sample descriptive indicators that were perceived by respondents as necessary for the SDE profession to contribute to the implementation of sustainable development policies.
The performed tests pointed to a 14 characteristics combination perceived as relevant to the respondents for the SDE profession to contribute to the implementation of sustainable development policies. The 14 characteristics are presented in
Table 2. A new reliability Cronbach’s alpha internal consistency test was performed for the new sample, and the calculated value of 0.893 indicated a very good fit of the sample.
According to
Table 2, the minimum average score calculated for the perceived necessary SDE characteristics is greater than 3.7. This value is considered a minimum threshold value for the Likert perception of the necessary SDE characteristics that provides significance to the contribution of the SDE profession in the implementation of sustainable development. The findings indicate that characteristics perceived with values lower than 3.7 have no significant statistical relevance for the SDE contribution to the implementation of sustainable development.
According to
Table 3, several significant correlations were identified between the analysed variables; the values greater than 0.5 were considered very strong and values greater than 0.4 were considered strong. All of the calculated correlations were found to be positive. These correlations provide valuable insights into the perceived profile of the SDE profession and the connections that are perceived by the sample respondents as necessary and interconnected for the profession to contribute to the implementation of sustainable development policies.
The very strong correlation between X10 and X11 (0.618) suggests that the perception of the high environmental specialization of SDE significantly impacts the necessity of the improvement of the territorial and local specialization of SDE. Furthermore, the very strong correlation between X13 and X14 (0.717) indicates that the perceived necessary negotiation competence of SDE significantly impacts the necessity of high communication skills of SDE professionals. X14 also exhibits significant correlations with X2 (0.415), X3 (0.427), X5 (0.502), X6 (0.456) and X12 (0.509), indicating that good communication competencies are increased by SDE professional implementing and reporting attributions, good planning and interrelations knowledge, together with the perceived necessity of analytical competences.
The correlations between X4 and X12 (0.572), X1 and X12 (0.520) and X5 and X12 (0.519) suggest that professionals with required high analytical knowledge, evaluation attributions and good planification knowledge are more likely to receive analytical competence while performing the SDE tasks. The same logic would also apply to the correlation between X6 and X13 (0.521), X12 and X13 (0.476), X3 and X13 (0.436) and X5 and X13 (0.407), where the perception indicated that good interrelation knowledge, negotiation competence, reporting attributions and good planning knowledge are characteristics that impact the increase in negotiation competencies.
Table 3 indicates significant correlations between X4 and most of the sample variables analysed, meaning that analytical knowledge is perceived as a key characteristic of the SDE profession, with extensive correlations with the perceived need for specialization, knowledge, attributions and competence that the SDE profession should need to contribute to the implementation of sustainable development policies.
Table 4 presents the calculated results higher than 0.88 for all the Cronbach’s alpha if deleted, which indicates the significant contribution of all fourteen items for the good internal consistency of the study.
The next steps of the analysis considered the 14 categories identified as relevant to fulfil the research objectives and performed a multinominal logistic regression, where the predicted variable was the contribution of the SDE profession to the implementation of sustainable policies. The regression considered regulations awareness as the dichotomous predictor variable of the model, and the 14 relevant characteristics described in the previous test as continuous predictor variables. The SDE contribution was a categorical variable, assessed as an insignificant contribution, some contribution or a very significant contribution.
The Likelihood Ratio Test compared the analysed model against an intercept-only model (null model). The calculated chi-square (χ2(30) = 88.68) and the p-value < 0.001 indicated that the full model represents a statistically significant improvement in fit over the intercept-only model.
The goodness-of-fit analysis showed that the Pearson chi-square test (χ2(400) = 413.398, p = 0.308 > 0.05) and Deviance chi-square (χ2(400) = 285.958, p = 1.00) exhibited a good fit to the data.
The overall contribution of each predictor variable to the model was calculated with the Likelihood ratio tests, as shown in
Table 5. The interpretation of results used the conventional α = 0.05 threshold. Several significant predictors were obtained in the model.
For the knowledge category of predictors, relevant were perceived to be interpersonal knowledge skills (p = 0.013), analytical thinking (p = 0.045) and planning abilities (p = 0.072). For the Specialization category of predictors, relevant was perceived to be the social professional specialization (p = 0.025). For the Attribution category of predictors, relevant was perceived to be evaluation attributions (p = 0.001) and reporting attributions (p = 0.040). The perceived significance of Competence predictor variables was attributed to analytic (p = 0.019), negotiation (p = 0.002) and communication (p = 0.022) competencies. Regulations awareness was also identified as significant for the analysis (p = 0.022).
The parameters estimation showed very interesting results in terms of the respondents’ perception regarding the SDE contribution to the implementation of sustainable development policies.
The first set of coefficients (A) in
Table 6 presents the comparison between the perceptions of insignificant contribution and the perception of some contribution of SDE to the implementation of sustainable development policies.
On the one hand, Reporting attributions (B = 1.161, s.e. = 0.478, p < 0.05), Communication competencies (B = 1.639, s.e. = 0.751, p < 0.05) and analytical knowledge (B = 0.850, s.e. = 0.399, p < 0.05) of SDE were identified as significant predictors in the model, as necessity perceptions scoring higher on this variables were more likely to bring some contribution to the implementation of sustainable development policies. The calculated exponential beta coefficients for each significant predictor indicate that for every unit increase in the perception of necessity attributed to Reporting attributions (eB = 3.193), Communication competencies (eB = 5.153) and analytical knowledge (eB = 2.339) of SDE profession, the increase in the perception of some contribution attributable to SDE in implementing sustainable development strategies would be changed by a corresponding factor to the odds ratio. In other words, for one unit increase in reporting attributions, the odds of some perceived contribution of SDE to the implementation of sustainable development policies is 3.193 times greater. For one unit increase in communication competencies, the odds of some perceived contribution of SDE to the implementation of sustainable development policies is 5.153 times greater. For one unit increase in analytical knowledge of SDE, the odds of some perceived contribution of SDE to the implementation of sustainable development policies is expected to increase by a factor of 2.339.
On the other hand, Evaluation attributions (B = −2.139, s.e. = 0.683, p < 0.05) and Negotiation knowledge (B = −2.076, s.e. = 0.728, p < 0.05) were identified to be significant predictors in the model, which suggests that perceptions of necessity scoring higher on these variables are less likely to bring some contribution to the implementation of sustainable development policies
The analysis of the first set of coefficients (A) did not identify a statistically significant contribution of Regulations awareness to the perception of some contribution of SDE to the implementation of sustainable development policies.
The second set of coefficients (B) in
Table 6 presents the comparison between the perceptions of insignificant contribution and the perception of the very significant contribution of SDE to the implementation of sustainable development policies.
The significant predictors in the model that were perceived to be highly necessary in order for SDE to more likely very significantly contribute to the implementation of sustainable development policies were identified to be Interrelationships knowledge (B = 1.130, s.e. = 0.445, p < 0.05), Territorial specialization (B = 1.607, s.e. = 0.517, p < 0.05) and analytical knowledge (B = 1.083, s.e. = 0.451, p < 0.05). According to the results, for one unit increase in Interrelationships knowledge, the odds of the perceived very significant contribution of SDE to the implementation of sustainable development policies is 3.096 times greater. For one unit increase in Territorial specialization, the odds of the perceived very significant contribution of SDE to the implementation of sustainable development policies is 4.987 times greater. For one unit increase in analytical knowledge of SDE, the odds of the perceived very significant contribution of SDE to the implementation of sustainable development policies is expected to increase by a factor of 2.953.
Other significant predictors identified in the model to negatively influence the perception of the very significant contribution of SDE to the implementation of sustainable development policies are similar to the ones in the first set of coefficient analyses: Evaluation attributions (B = −2.179, s.e. = 0.738, p < 0.05) and Negotiation knowledge (B = −2.199, s.e. = 0.762, p < 0.05). An interesting result is finding that Regulations awareness significantly negatively influences the comparison between the perceptions of insignificant contribution and the perception of the very significant contribution of SDE to the implementation of sustainable development policies (B = −1.632, s.e. = 0.715, p < 0.05). The results indicated that the persons aware of the sustainability regulations perceive that the SDE occupation would less likely to bring a very significant contribution to the implementation of sustainable development policies. The observed relationship between evaluation attributions or negotiation knowledge and sustainable development policies highlights the perception of Romanian civil servants on the SDE occupation. Given that the benefits of sustainable development policies are in an early stage in the public sector in Romania, such features seem to bring feeble benefits for the effective implementation of sustainable development policies. It is interesting to develop similar investigations in the private sector, where similar features of SDE professions, such as evaluation attributions or negotiation knowledge, can bring significant contributions to the implementation of sustainable development policies.
The classification statistics presented in
Table 7 indicated which group memberships were better predicted by the model. The characteristics of the SDE occupation that provide some contribution to the implementation of the sustainable development policies were correctly predicted by the model 86.9% of the time, as 133 of the 153 responses indicated some contributions were correctly predicted by the model. The characteristics of SDE that bring an insignificant contribution or a very high contribution were not correctly predicted. The situation is supported by the previous findings, which point to a moderate contribution of the SDE occupation to the overall implementation of sustainable development policies.
The sample respondents who stated that they had knowledge of sustainability regulations did not perceive the SDE occupation to make a great contribution to the implementation of sustainable policies. At the same time, previous research studies and everyday reality clearly show that the need for sustainable policy implementation is real and present [
57]. As a result, the findings of this study bring a very important perspective from the empirical dimension, creating a profile of those key characteristics attributable to the persons in charge of implementing sustainable development policies that can contribute with statistically significant accuracy (86.9%) to the implementation of sustainable development procedures: analytical knowledge, reporting attributions and communication skills. As a consequence, the study led to the development of a competency matrix for the SDE occupation to ensure the implementation of sustainable development policies. Our first hypothesis (H1) was validated.
Another significant observation of the study was that the specialization of the people in charge of implementing sustainability policies was not found to be statistically significant. The predictors included in the analysis referring to economic, technical, environmental and social specialization did not show statistical significance (p > 0.05) in terms of respondents’ perceived need to implement sustainable development policies. According to the respondents, sustainability policies may be implemented by persons with either economic, technical, environmental or social education skills. Similarly, planning knowledge was also not perceived by respondents as necessary, as SDE activity is perceived as predominantly oriented towards compliance and the reporting of events that occurred or publicly reported decisions issued by corporate governance representatives. The conclusion of this phase of the study led to the partial validation of the second hypothesis (H2) that the SDE occupation substantially contributes to the implementation of sustainable development policies in the public sector. As the SDE professional advice becomes integrated into the organizational system and meets the characteristics identified in the green competency matrix, public perception of the usefulness of the SDE occupation is also likely to improve.
5.1. Theoretical Implications
The findings of this paper add interesting insights to theoretical research. A competency matrix for the experts in charge of implementing sustainable development policies within their working institutions is developed. In addition, the perception of the usefulness of this competency is drawn based on the perception of employees working in public institutions. This study suggests that the perception of the respondents of the high necessity of two main requirements imposed by SDE, namely evaluation attributions or negotiations knowledge, would less likely bring any contribution to the implementation of sustainable development policies. The contribution of SDE to proactive sustainable development within organizations [
58] is not favoured by evaluation attributions or negotiation knowledge since this occupation is not perceived as intended to negotiate or evaluate any of the sustainable policies that are to be implemented. The experts designated to implement sustainable policies in their working institutions, especially in the public sector, should encourage a climate of conformity and ethical behaviour to achieve positive sustainable outcomes. These findings are consistent with studies in private companies, that have supported the importance of ethical values for sustainable development [
32]. Organizations and public entities should proactively implement the execution of sustainable development policies by imprinting values such as ethics and compliance among their employees.
In addition, this study shows that the competency matrix of a reliable SDE occupation should include characteristics such as very good knowledge of interpersonal relations, in-depth local knowledge and strong analytical knowledge. Such characteristics can make a very significant contribution to the implementation of sustainable development policies and to the increase in social capital [
5]. Another interesting finding is that the usefulness of the expertise in implementing sustainable development is better observed through the competency matrix than through a SDE occupation, as an employed individual activity. The perceived mismatch between evaluation and negotiation skills and the practical usefulness of the SDE occupation, coupled with the inverse relationship between legislative knowledge and the perceived very significant contribution of the SDE occupation, suggests that respondents’ opinion places the role of the SDE-employed occupation in a formal area with no significant practical benefits. These findings resonate with the outcomes of previous studies based on surveys that observed discrepancies between the formal sustainable declarations of companies regarding sustainability strategies and practical outcomes [
28,
59]. Consequently, the outcome suggests that to effectively implement sustainable institutional policies, organizations should promote collective participation and a proactive working environment throughout the sustainable implementation procedures.
5.2. Practical Implications
The findings of the study are very important for practice and building on empirical knowledge by raising awareness of the significance of ethics, compliance and a collaborative working environment in achieving sustainable development. According to our analysis sample, good implementation of sustainable development policies, based on good knowledge of regulations, does not necessarily need to be carried out by a specific person employed in this role or distinct occupation, such as SDE. Good implementation of sustainable development policies can be carried out by people with good knowledge of human interactions, in-depth local knowledge and good analytical skills, able to carry out reporting and implement procedures.
The results of the research can also be useful both in calibrating professional training/specialization programmes that provide the cross-cutting and horizontal competences required of a sustainable development expert, and in developing interview tools that can be used by human resources departments in central and local government in human resources selection processes.
5.3. Limitations of the Study and Further Developments
The limitations of this study are mainly represented by the fact that the study was carried out in a restricted geographic area, the territory of Romania, and by the analysis of the perceptions of a significant number of respondents working in public administrations. The research sample did not include respondents working in private sector organizations. Although the analysis was carried out on a statistically significant group of respondents, by number, the field of activity and place of work, the answers may be affected by the subjectivity specific to a certain geopolitical area [
30,
60] or by the incidence of specific national regulations. This limitation of the study also represents an opportunity for future research development. Research needs to further expand similar analysis into wider geographic areas and the private sector. Expanding the sample of respondents by also including respondents from other countries may contribute to the development of comparative investigations into the perceptions and usefulness of the competency matrix of sustainability development expert professionals.
